AGREEMENT. IF YOU DO NOT AGREE TO ALL OF THE TERMS OF THIS END USER AGREEMENT, PROMPTLY RETURN
AND DO NOT USE THE EQUIPMENT AND THE SOFTWARE.
1. Single User License. Subject to the terms and conditions of this EULA, Overland Storage, Inc. (“Overland”) grants to you
(“Customer”) a non-exclusive, non-transferable license to use (a) Overland software which provides the basic operating environment
for Overland equipment and whether pre-installed on, embedded in or provided with Overland equipment, and (b) the specific
Overland program modules or features which have been enabled by security keys supplied by Overland and for which Customer had
paid any applicable license fees (collectively, the “Software”), both of the foregoing in object code form only: (i) solely as pre-installed,
embedded in or provided with Overland equipment owned or leased by Customer; and (ii) for key-enabled Software corresponding to
the security key(s) supplied by Overland and for the license fees paid by Customer.
2. Limitations. Except as otherwise expressly provided under this EULA, Customer will have no right, and Customer will not:
(i) make error corrections to or otherwise modify or adapt the Software nor create derivative works based upon the Software, or to
permit third parties to do the same;
(ii) copy, in whole or in part, de compile, translate, reverse engineer, disassemble or otherwise reduce the Software to humanreadable form; or
(iii) remove the Software from the equipment in which it is embedded.
3. Upgrades and Additional Copies. For purposes of this EULA, “Software” will also include (and the terms and conditions of this
EULA will apply to) any upgrades, updates, bug fixes or modified versions (collectively, “Upgrades”) or backup copies of the Software
licensed or provided to Customer by Overland or an authorized distributor for which Customer had paid the applicable license fees
and holds the corresponding software keys. Notwithstanding the foregoing, Overland will have no obligation to provide any Upgrades
under this EULA. If Upgrades are provided, (i) Customer has no license or right to use any such additional copies or Upgrades unless
Customer, at the time of acquiring such copy or Upgrade, already holds a valid license and the corresponding security keys to the
original Software; and (ii) use of the Upgrades is limited to Overland equipment for which Customer is the original End-User
purchase or lessee.4. U.S. Government Restriction Rights. The Software was developed at private expense and is provided with
“RESTRICTED RIGHTS” as set forth in this License Agreement. Use, duplication or disclosure by the United States government is
subject to restrictions as set forth in FAR 52.227-14 and DFARS 252.227-7013 et seq., or its successors. The use of this Software
constitutes acknowledgement of Company's and its licensors' rights in the Software.
4. Notices of Proprietary Rights. Customer will maintain and reproduce all trademark, copyright, patent, and notices of other
proprietary rights on all copies, in any form, of the Software in the same form and manner that such trademark, copyright, patent,
and notices of other rights are included on the Software. Except as expressly authorized in this EULA, Customer will not make any
copies or duplicates of any Software without the prior written permission of Overland.
5. Proprietary Rights. The Software is and will remain the sole and exclusive property of Overland. Software is licensed, not sold,
by Overland hereunder. Any references to terms in connection with the foregoing, such as “sale”, “purchase” or “sell” will be
interpreted as licensed rights granted on a non-exclusive basis hereunder and as otherwise provided in this EULA. Overland's rights
under this Section will include, but not be limited to: (i) all copies of the Software, in whole and in part; and (ii) all intellectual
property rights in the Software.

AND WARRANTIES INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTY OR CONDITION OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, SATISFACTORY QUALITY OR
ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE, ARE HEREBY EXCLUDED TO THE EXTENT
ALLOWED BY APPLICABLE LAW. IN NO EVENT WILL OVERLAND OR ITS SUPPLIERS BE LIABLE FOR ANY LOST
REVENUE, PROFIT, OR DATA, OR FOR SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, OR PUNITIVE DAMAGES
HOWEVER CAUSED AND REGARDLESS OF THE THEORY OF LIABILITY ARISING OUT OF THE USE OF OR INABILITY TO
USE THE SOFTWARE EVEN IF OVERLAND OR ITS SUPPLIERS HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES. IN NO EVENT WILL OVERLAND'S TOTAL LIABILITY TO CUSTOMER, WHETHER IN CONTRACT, TORT
(INCLUDING NEGLIGENCE), OR OTHERWISE, EXCEED THE PRICE PAID BY CUSTOMER. THE FOREGOING
LIMITATIONS WILL APPLY EVEN IF THE ABOVE-STATED WARRANTY FAILS OF ITS ESSENTIAL PURPOSE.
Each party recognizes and agrees that the warranty disclaimers and liability and remedy limitations in this EULA are material
bargained for bases of this EULA and that they have been taken into account and reflected in determining the consideration to be
given by each party under this EULA and in the decision by each party to enter into this EULA.
9. Term and Termination. This EULA is effective until terminated. Customer's license rights under this EULA will terminate
immediately without notice from Overland if Customer fails to comply with any provision of this EULA. Upon termination, Customer
must destroy all copies of Software and the corresponding security keys in its possession or control.
10. Compliance With Law. Each party will comply with all applicable laws, rules and regulations in connection with its activities
under this EULA. Without limiting the foregoing, the Software, including technical data, is subject to United States export control
laws, including the United States Export Administration Act and its associated regulations, and may be subject to export or import

and (i) FAR 12.212(a); (ii) FAR 52.227-19; or (iii) FAR 52.227-14 (ALT III), as applicable.
12. Third Party Software. Third party suppliers of materials integrated with the Overland equipment disclaim all implied
warranties, including the implied warranties of merchantability and fitness for a particular purpose. The collective liabilities of the
seller/licensor and its third party suppliers are subject to the limitation of liabilities described in this agreement. The third party
supplier is an intended beneficiary of this limitation.” Third party suppliers disclaim all liability for consequential or other indirect
damages or for loss of or damage to data or records.
13. General. This EULA will bind and inure to the benefit of each party's successors and assigns, provided that Customer may not
assign or transfer this EULA, in whole or in part, without Overland' written consent.
This EULA will be governed by and construed in accordance with the laws of the State of California, United States of America, as if
performed wholly within the state and without giving effect to the principles of conflict of law.
No failure of either party to exercise or enforce any of its rights under this EULA will act as a waiver of such rights.
Any waivers or amendments will be effective only if made in writing by non-preprinted agreements clearly understood by both parties
to be an amendment or waiver and signed by a representative of the respective parties authorized to bind the parties.
If any portion hereof is found to be void or unenforceable, the remaining provisions of this EULA will remain in full force and effect.
This EULA is the complete and exclusive agreement between the parties with respect to the subject matter hereof, superseding and
replacing any and all prior agreements, communications, and understandings (both written and oral) regarding such subject matter.
Any notice, report, approval or consent required or permitted hereunder will be in writing and will be deemed to have been duly given
if delivered personally or mailed by first-class, registered or certified US mail, postage prepaid to the respective addresses of the
parties. The prevailing party in any action to enforce this EULA will be entitled to recover costs and expenses including, without
limitation, reasonable attorneys' fees.
A material breach of this EULA adversely affecting Overland's proprietary rights in the Software would cause irreparable injury to
Overland for which monetary damages would not be an adequate remedy and that Overland will be entitled to equitable relief in
addition to any remedies it may have hereunder or at law.

Preface

The Overland Storage REO 9000 Disk-Based Backup-and-Recovery
Appliance takes the lag time, expense, and burden out of backing up
critical data and works seamlessly within current storage environments.
The REO Appliance performs faster than traditional disk-based storage
methods and serves as a shared network resource by utilizing highcapacity disks, high-speed Ethernet and Internet SCSI (iSCSI)
connectivity, and unique software intelligence capability from Overland
Storage.
The REO Appliance comes with a standard software package called the
ProtectionPAC. The ProtectionPAC software contains all the basic
features that you need to configure your REO Appliance to work within
your network environment.
This document includes information that helps you set up the REO
Appliance, including system requirements, questions that you need to
answer before installing the product, and installation procedures.

Important: If you purchased multiple units, set up (attach and
configure) one unit at a time. The target names must be unique within
a network; that is, if you are using multiple appliances, you must
change the default target names.
Also, be aware that the keys are not interchangeable and Overland
strongly recommends that you make a backup copy of the files on the
keys before and after you configure them.

CHAPTER

Reviewing REO 9000 Concepts
and Requirements

The main steps involved in preparing to set up the REO Appliance
include:
Step 1 Understanding the concepts of iSCSI, Fibre Channel (FC), disk-to-diskto-tape (D2D2T) backup, redundant array of independent disks (RAID),
tape emulation, logical volume management (LVM), and how the REO
Appliance fits into the picture.
Step 2 Reviewing the requirements that your servers and network must meet to
ensure successful installation and operation of the REO Appliance.

Important Concepts to Understand
To understand the configuration of the backup network and how it fits
into the local-area network (LAN) or Fibre Channel (FC) storage-area
network (SAN), review the following sections.

Internet SCSI (iSCSI) Protocol
Internet SCSI (iSCSI) is a standard protocol for universal access to
shared storage devices over standard, Ethernet-based transmission
control protocol/Internet protocol (TCP/IP) networks. The connectionoriented protocol transports SCSI commands, data, and status across an
IP network. For more information, see Glossary and Acronym List on
page 163.

iSCSI Architecture
The iSCSI architecture is based on a client-server model. The client is a
host system that issues requests to read or write data. iSCSI refers to a
client as an initiator. The server is a resource that receives and executes
client requests. iSCSI refers to a server as a target.
File servers, which store the programs and data files shared by users,
normally play the role of server. With the REO Appliance, the application
and backup servers within your network act as clients or initiators and
the REO Appliance acts as a server or target. The initiators can either be
software drivers or iSCSI host bus adapters (HBAs) on the server that is
being backed up.

Fibre Channel (FC)
Instead of, or in addition to, using iSCSI and the TCP/IP protocol to
transmit information over a network, you also have the option of using a
SAN that makes use of the FC and Small Computer System Interface
(SCSI) protocols. The FC protocol uses two additional protocols to
communicate at the hardware level: Fibre Channel Arbitrated Loop (FCAL), which communicates with hubs, and Fibre Channel Switched (FCSW), which communicates with switches. The SCSI protocol provides the
communication link at the higher level, between the hardware and the
software.
You can use all three basic FC SAN topologies with the REO Appliance:

Point-to-point. This topology provides a direct connection between
two N_Ports.

Arbitrated loop. In an arbitrated loop, NL_Ports and FL_Ports are
daisy-chained with hubs, which means that only one device can send
data at a time.

Switched fabric. Switched fabric consists of one or more switches
that are interconnected, and multiple nodes connected to the switches.

The REO Appliance supports the following types of ports for FC:

FC uses strict naming conventions to support unique, 64-bit names for
the worldwide node name (WWNN) and the worldwide port name
(WWPN). These names are pre-assigned by the manufacturers of the
different hardware components used in an FC.

Redundant Array of Independent Disks (RAID)
RAID provides convenient, low-cost, reliable storage by saving data on
more than one disk drive simultaneously. If one disk drive in a RAID 5
configuration becomes unavailable, the others continue to work in a
degraded state, thus avoiding downtime for users.

Note: Because RAID 5 is designed for data protection, you might see
performance degradation when compared to JBOD operations.
RAID allows you to group the individual disk drives on the REO
Appliance into logical disk drives of different sizes. You can configure
your REO Appliance to create two physical RAID volumes by selecting
either of the following RAID options:

RAID 0. This configuration uses striping, which provides enhanced
performance and volume-level capacity. It divides the data into blocks
and writes each block to a separate disk drive, which improves
performance by dispersing the input and output load. RAID 0 does not
provide data redundancy.

RAID 5. This configuration uses striping and distributed parity,
which provides a balance between performance and availability. In
addition to dividing the data into blocks as described for RAID 0, the
parity information is also striped across the disks. If one of the disk
drives fails, you can use the parity information to rebuild the lost data.

In addition to using either of the preceding RAID configurations, you can
also take advantage of logical volume management (LVM) and create
logical volumes from the data pool.

Important Concepts to Understand W 15

Overland Storage REO 9000 with ProtectionPAC Software

If you use a RAID 5 configuration, you can also set aside a disk drive for
each physical host (controller); that is, you can create a hot spare. These
disk drives remain in standby mode, and you can use them immediately
if another disk fails.

Tape Emulation
The ProtectionPAC software includes two tape emulation features, which
you can use to create virtual linear tape-open (LTO-2) tape devices that
provide 2-to-1 compression ratios with typical data sets (actual
performance might vary with application). When you use tape emulation,
the disk drives on the REO Appliance appear to your backup software as
LTO-2 tape drives, which simplifies the setup process while
simultaneously providing data compression and the attributes of backing
up data to disk.
Depending on the configuration that you use, you get a different number
of virtual LTO-2 devices. In the just-a-bunch-of-disks (JBOD)
configuration, you can have up to 24. If you use RAID 0 or 5 without
logical volumes, you can have four. If you use logical volumes with
RAID 0 or 5, you can create up to 64 virtual LTO-2 devices.
If you decide to use tape emulation, you also have the option of using
fixed-length (Tape) or dynamic-length (Dynamic Tape) devices. To take
advantage of the Dynamic Tape option, you must use logical volumes,
which is described in the next section. Using Dynamic Tape lets you
create devices that adjust to the size of individual backup jobs.

Logical Volume Management (LVM)
With LVM, you can combine the two physical RAID volumes into
multiple logical volumes (partitions) of different sizes and assign logical
unit numbers (LUNs) to represent the different volumes, or REO devices.
This feature lets you set up and assign devices to different systems
according to your needs and the configuration and type of storage
network that you use.
Using this feature in the ProtectionPAC software, you can create up to 64
LUNs, and you can reassign space allocation for disk or standard (not
dynamic) virtual tape devices, in 1 gigabyte (GB) increments, on the fly.

Reviewing Pre-Installation Requirements
Before attempting to operate the REO Appliance with your backup
servers, verify that your network meets the minimum requirements
specified in the following sections.

16 X Reviewing REO 9000 Concepts and Requirements

Setup Guide

Network
For best results, Overland Storage strongly recommends that you use a
dedicated GbE network to share the storage resources on the REO
Appliance among multiple backup servers.
To ensure optimum performance, always use the appropriate patch
cables to connect the REO Appliance to the backup-server storage
network. To select the appropriate cables, use the following guidelines:

If you intend to use GbE, you must use Category 5E (or better) cables
for GbE connections. You can use either straight-through or cross-over
cables.

If you intend to connect the REO Appliance to a 100 BaseT network,
use CAT 5 (or better) shielded (screened) or unshielded 100-ohm
twisted-pair RJ-45 network cables. Also:

If you intend to connect the Management Port, which is a 10/100
port, to an application or backup server via a switch, you must use
a straight-through cable.

If you intend to connect the Management Port directly to your
application or backup server (without a switch), you must use a
cross-over cable.

The maximum length of cable for any Ethernet-based network
connection is 328 feet (100 meters).

Note: For smaller environments, you can attach the REO Appliance
directly to a single application or backup server by using standard
Category 5E cables without the use of a switch.

iSCSI Initiators
iSCSI initiators are required to communicate with the iSCSI targets
(REO Devices) on the REO Appliance. Each backup server that will
interface with the REO Appliance must be equipped with a software- or
hardware-based initiator. The REO Appliance supports any computing
platform with an available iSCSI initiator, either in software or using an
iSCSI HBA (it must be iSCSI draft 20/version 1.0).

Reviewing Pre-Installation Requirements W 17

Overland Storage REO 9000 with ProtectionPAC Software

Setting the SCSI Time-Out Value in Windows
Environments
If you intend to use your REO Appliance in a Windows environment, be
aware that there are certain operating conditions in which time-out
errors might occur. These errors usually result in the system reporting a
disk failure for the associated REO Appliance disk drive or drives. (These
errors might be reported as iSCSIPrt errors in the System Log of the
Event Viewer. Examples include an Event ID 9 [Target did not respond
in time for a SCSI request…] and Event ID 39 [Initiator sent a task
management command to reset the target…]. Other symptoms might
include “Lost Delayed Write Data” system error messages or similar
error messages related to the REO Appliance disk drives.)
The reason that these disk time-out errors can occur is because the
default I/O time-out value for Windows is 20 seconds, which is not
sufficient to support the default iSCSI protocol time-out value of 60
seconds. When you install and set up your REO Appliance, Overland
strongly recommends that you set this value to 60 seconds.
To set the time-out value to 60 seconds
1 On the Windows system, run regedit.

Warning: If you edit the registry incorrectly, you might cause serious
problems that require you to reinstall your operating system. Edit the
registry at your own risk. Prior to making any changes, refer to the
following Microsoft Knowledge Base article:
http://support.microsoft.com/default.aspx?scid=kb;en-us;322755
2 In HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Services\Disk, edit or add the TimeOutValue entry to set it to 60
seconds in decimal format ((0000003c in hexadecimal).

To edit the value for the TimeOutValue entry if it already exists,
double-click the entry, enter the new value, and click OK.

To add the TimeOutValue entry if it does not yet exist, right-click
anywhere in the list of values, and then click New > DWORD value.
Name the new value TimeOutValue, and then double-click it to edit
the setting.

2 Review the following guidelines prior to positioning the REO Appliance
physically within your network.

Make sure that the REO Appliance is accessible.

Make sure there is unrestricted air flow around the unit and through
the vents in the sides and rear of the case.

Route external cables so that they can be connected easily without
blocking air vents or impeding air flow.

Protect the REO Appliance from extreme temperature and humidity.
Overland Storage recommends that you install the REO Appliance in
a clean, air-conditioned environment where water and moisture
cannot enter the case of the REO Appliance. Keep the air as free from
dust as possible.

Protect the REO Appliance from physical shock and vibration.

Make sure that the inlet air temperature within the rack remains
below the specified limit of 95°F (35°C).

Keep the REO Appliance and cabling away from sources of electrical
noise such as elevator shafts, stereo speakers, microwave ovens, air
conditioning units, and even telephones. Electromagnetic fields can
interfere with the signals on copper cabling and introduce errors,
therefore slowing down the network.

Attaching the Power Cords
1 Attach all four power cords to the REO Appliance.
2 Plug the power cords in to an AC power source (do not turn the power on).

Important: You must connect and use all four power cords; if one of the
cords is disconnected or malfunctioning, the REO Appliance beeps
repeatedly until the situation is resolved. Overland Storage
recommends that you use separate power mains for the power sources.
If you are not using Dynamic Host Configuration Protocol (DHCP), it
is critical to the configuration process that you refrain from enabling
power to the REO Appliance before completing the configuration steps
specified in the next chapter.
Power problems can be the cause of serious failures and downtime in
your network. Ensure that the power input to your system is clean and
free from sags and surges to avoid unforeseen network outages. Overland
Storage strongly recommends that you install power conditioning and an
adequately rated uninterruptible power supply (UPS), especially in areas
prone to blackouts, power dips, and electrical storms.
The REO Appliance is intended to be grounded. Ensure it is connected to
earth ground during normal use. Installing proper grounding helps to
avoid damage from lightning and power surges.

Step 1 Making a backup copy of the key.
Step 2 If your network does not use DHCP, manually editing the configuration
and network files on the key.
Step 3 Connecting the key to the REO Appliance.

Understanding What the REO SoftKey Is
The REO SoftKey is a removable USB disk drive on a key ring. It
contains the software and settings required for configuring the REO
Appliance and must be inserted in the REO Appliance whenever you
restart it (because the REO Appliance uses a Linux-based OS, the key is
formatted using the virtual file allocation table [VFAT]). You can also use
the REO SoftKey to download and install updates when they become
available.

Important: If you purchased multiple units, note that the keys are not
interchangeable
The simplest configuration can be achieved when your LAN uses
DHCP on its own subnetwork (subnet). If your LAN does not use
DHCP, you must manually edit the configuration file located on the
REO SoftKey before continuing.

3 Use the default network drive displayed or select another drive from the
list.

Tip: For consistency, Overland Storage recommends that you select a
drive letter, such as drive Z, that is available to all systems on the
backup network.
4 In the Folder box of the Map Network Drive dialog box, type
\\REO\programs, and make sure that the Reconnect at login box is
cleared.

Note: Because the folder might not be visible if you use the Browse
button, Overland Storage recommends that you type \\REO\programs
directly in the Folder text box.

5 Click Finish.

Overland Storage REO 9000 with ProtectionPAC Software

Verifying that the Gateway Address and
Management Port are Correctly Configured
The Default Gateway is the IP address that provides entrance into the
network to which the REO Appliance is assigned. The Management Port
connects the REO Appliance to the management system, which you use
for network management on the LAN.

Important: Remember that the Management Port and both Data Ports
must be on separate subnets.
1 Using the management system, access the mapped drive
\\REO\programs.

2 To open the REO Appliance console in your Web browser, double-click the
Overland.html file.

Tip: After you have initially configured your REO Appliance, if you are
not using DHCP, you can also access the interface by typing the IP
address assigned to the Management Port for the REO Appliance.

To launch the console,
double-click Overland.

The REO Appliance console appears.

Tip: To access online help on any of the pages in the console, click Help
under System Menu or click the Help button that appears on each of
the pages.

To access help at any time, click Help.

4 In the left pane, under System Menu, click Network Configuration.

Click Network Configuration.

5 If you are not using DHCP, in the Default Gateway section of the right
pane, make sure that the correct IP Address appears.
If DHCP is disabled, the IP address and other information is completed
using information from the configuration file that you previously
modified (for more information, see Editing the Configuration File (for a
non-DHCP or UNIX Management System) on page 33).

Verify that this is the
correct information
for your network.

54 X Configuring the Management System

Setup Guide

6 In the Management Port section, verify the following:

If your network uses DHCP (recommended), make sure that Enable
is selected. The Management Port is automatically configured when
DHCP is enabled. This is the default setting. (If you are using DHCP,
the system displays the addresses that are currently being used.)

If your network does not use DHCP or you are using a UNIX-based
system, make sure that the correct addresses appear and that Disable
is selected.

7 Continue the configuration process by configuring the GbE data ports as
described in the next section.

Configuring the GbE Data Ports
The GbE data ports are used for block-level data transport between your
backup servers and the REO Appliance. Data Port 1 and Data Port 2 are
fully interchangeable prior to configuration.

Important: Remember that the Management Port is on the LAN (a
10/100 network); use Data Port 1 and Data Port 2 on separate subnets
of the backup network. Data Port 1 and Data Port 2 each require an
available static IP address within their respective subnets. If you want
to manage the REO Appliance from the same port, use the GbE (Data
Port 1 or 2) IP address. Entering this IP address in your browser
displays the REO Appliance software console.
If you have one or two backup servers, you can connect each one directly
to one of the data ports on the REO Appliance. The backup servers must
have a GbE port. If you have more than two backup servers, you must
make these connections through a GbE switch.
To configure the GbE ports
1 In the right pane, scroll down below the Management Port section to
locate the Data Port 1 and Data Port 2 sections.
2 In the Data Port 1 section, enter the following:

IP Address. Using dotted decimal notation, enter an available static
IP address that falls within the Data Port 1 subnet. An example of an
address is: 192.168.1.4.

Subnet Mask. Using dotted decimal notation, enter the subnet
address. An example of an address is: 255.255.0.0.

Tip: If you change one of these settings, such as the IP Address, you
might need to reconnect to the server via your Web browser.

Configuring the GbE Data Ports W 55

Overland Storage REO 9000 with ProtectionPAC Software

3 Click Apply.
4 Repeat these steps for Data Port 2 using an IP address that falls within
the Data Port 2 subnet.

Tip: Overland Storage recommends that you use a ping command to
ensure that the management system sees each port on the REO
Appliance.
5 If you purchased the FC-enabled REO Appliance, continue the
configuration process by entering the FC information described in the
next section; otherwise, proceed to the subsequent section, Entering the
System Information on page 57.

Entering the Fibre Channel Information
1 In the right pane, scroll down to the Fibre Channel Configuration
section.
2 For each FC port (the REO Appliance provides two), select the applicable

CHAPTER

Configuring the Systems
Involved in the Backup Process

The main steps involved in configuring the backup servers include:
Step 1 Mapping the REO Appliance to a drive letter to simplify access to the
console and other installation and management tools.
Step 2 Installing software client drivers or storage adapters for iSCSI or FC
access.

Mapping a Network Drive to the REO Appliance
(Windows Only)
To access the components used for installation and configuration of the
REO Appliance, you must map a network drive from the system to a
folder located on the REO Appliance.
1 Make sure that the REO Appliance is still powered on and that the REO
SoftKey is still inserted in a USB port.
2 Perform the steps previously outlined under Mapping a Network Drive to
the REO Appliance (Windows Only) on page 39.
3 Repeat these steps for each system that will access storage on the REO
Appliance.

Establishing Communication
If you are using iSCSI connectivity, iSCSI initiators are required to
communicate with the iSCSI targets (REO Devices) on the REO
Appliance. Each backup server that uses the REO Appliance must be
equipped with a software initiator, such as the Microsoft iSCSI Software
Initiator, or an IP storage HBA, such as the Intel PRO/1000 T IP Storage
Adapter.

Note: You do not need TOE-equipped (Transmission Control Protocol
[TCP] Offload Engine) or special iSCSI-capable GbE HBAs to work
with software initiators. Any standard Network Interface Card (NIC)
can serve as an iSCSI network interface device; however, Overland
Storage strongly recommends that you use GbE for enhanced
performance.
If you are using FC connectivity, make sure that the applicable FC
initiator is installed.
Configuring the Systems Involved in the Backup Process W 61

Changing the Volume Setup or
Creating Logical Volumes

The main steps involved in switching from one configuration to another
or creating logical volumes include:
Step 1 Selecting the applicable configuration.
Step 2 Creating the desired number of logical volumes, and setting their size.

Using the Default Volume Setup
The REO Appliance uses a default volume configuration of RAID 5 with
logical volumes. To use this configuration, you must create the logical
volumes.
X

To use the default configuration and create logical volumes, proceed to
Creating Logical Volumes on page 71.

Changing the Volume Configuration
You can use the Volume Setup feature in the console to select a different
RAID configuration or to select the JBOD configuration.

Important: Be aware that the process of changing the volume
configuration takes time for the RAID 5 configurations while the
arrays are initialized. After you select the new configuration and the
initialization process begins, you can use the REO Appliance, but
performance will be impacted. Overland Storage strongly recommends
that you wait until the Status on the Physical Volume Management
page is OK (not INITIALIZING) before using a volume. (Switching to
a RAID 0 or JBOD configuration usually requires less than 10
minutes.)

residing on the REO Appliance will be deleted, click OK to continue.

4 When the message appears that indicates the REO Appliance must be
restarted, click OK to continue.

5 After waiting approximately five minutes, log on to the console, and then
proceed to the steps outlined in Configuring REO Devices as Disk or Tape
Devices on page 73.

Selecting a RAID Configuration
The REO Appliance supports RAID 0 and RAID 5. You can only select
one configuration; that is you cannot set up one volume to use RAID 0
and set up another to use RAID 5.

Important: Because the process of changing the volume configuration
takes time if you select a RAID 5 option, Overland Storage
recommends that you make your selection and let the process run
overnight. (Switching to a RAID 0 or JBOD configuration usually
requires less than 10 minutes.)
In a RAID configuration, how the volumes are arranged depends on
whether you are using an appliance that contains 12 physical disks or 24,
and it depends on whether those disks are 250 GB or 400 GB in size.
The appliance also contains two physical hosts (controllers). If you are
using 12 physical disks, they are all assigned to the first host; if you are
using 24 disks, the second set of disks is assigned to the second host.
If you select a RAID 5 option, you will also have the option of creating a
hot-spare disk drive for each physical host (controller) after you click
Submit. (These disk drives remain in standby mode, so that you can use
them immediately if another disk fails.)

Changing the Volume Configuration W 65

Overland Storage REO 9000 with ProtectionPAC Software

The following describes how the volumes are arranged in RAID
configurations, depending on the number of disks and their size.
If you are using the 12-disk appliance:

RAID 0. Creates three REO Devices. Each REO Device (physical unit
[PU]) is comprised of four disks. Each device provides either 1000 GB
(using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity.

RAID 5, without hot spare. Creates two REO Devices. Each REO
Device (PU) is comprised of six disks. Each device provides either 1250
GB (using 250 GB disks) or 2000 GB (using 400 GB disks) of capacity.

RAID 5, with hot spare. Creates two REO Devices and one hot-spare
disk. One REO Device (PU) is comprised of six disks and the other is
comprised of five disks. The five-disk device provides either 1000 GB
(using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity, and
the six-disk device provides either 1250 GB (using 250 GB disks) or
2000 GB (using 400 GB disks) of capacity.

If you are using the 24-disk appliance:

RAID 0. Creates six REO Devices (three physical units for each host).
Each REO Device (PU) is comprised of four disks. Each device provides
either 1000 GB (using 250 GB disks) or 1600 GB (using 400 GB disks)
of capacity.

RAID 5, without hot spare. Creates four REO Devices (two physical
units for each host). Each REO Device (PU) is comprised of six disks.
Each device provides either 1250 GB (using 250 GB disks) or 2000 GB
(using 400 GB disks) of capacity.

RAID 5, with hot spare. Creates four REO Devices (two physical
units for each host) and one hot-spare disk for each host. One REO

CHAPTER

Configuring REO Devices as
Disk or Tape Devices

You can configure each REO Device to function either as a disk device
(the default) or as a virtual LTO-2 tape device; that is, you can use each
device in its native disk format, virtual-tape format, or any combination
of the two.

Note: To use the ShareDevice feature (available only on Windows) with
a device, the device must be designated as a disk device. For more
information, see Sharing Access to a REO 9000 Between Multiple
Systems on page 115.
As explained previously, the number of devices that you have depends on
the volume configuration that you use. For example, if you use logical
volumes with RAID 5, you can create up to 64 disk LUNs, 64 virtual
LTO-2 tape devices, or any combination of LUNs and virtual LTO-2
devices up to 64 in total.

Using Devices as Disk Devices

Creating Tape Devices
If you intend to create devices of type Tape or Dynamic Tape, note the
following:

As with standard tape devices, a specific driver (on a Windows system)
or changes to a system configuration (on a UNIX system) might be
required to operate with your selected backup software. For more
information, check the Overland Storage Web site
(www.overlandstorage.com) for Application Notes related to your
specific backup software.

If you are using logical volumes, you can create dynamic tape devices,
which expand and contract to accommodate the size of a specific
backup job.

When you change the configuration of a device, all data currently
residing on the device is deleted.

Configuring REO Devices as Disk or Tape Devices W 73

If you choose to enable compression, be aware that various factors
(such as the speed of your backup server, source devices, or network)
can significantly affect performance. Additionally, the existing state of
the files you are backing up (for example, whether the files are already
compressed) can affect the level of compression that might be

CHAPTER

Configuring External (SCSI)
Devices

The SCSI ports on the REO Appliance let you attach external devices
(such as tape drives or changers) and then use the console to assign
initiators. The appliance provides two SCSI ports, and you can use a
chain formation to assign up to 15 SCSI IDs to each port (the SCSI IDs
must be unique within each port configuration).

Important: For a list of supported SCSI devices (some device-types and
configurations are not currently supported), see the REO
Interoperability Matrix on the Overland Storage Web site at
www.overlandstorage.com.

Detecting External Devices
When you enable power to the REO Appliance, it automatically detects
whether External Devices are attached to the SCSI ports and displays
the applicable information in the External Device Summary and

CHAPTER

Associating Targets (Devices)
and Initiators

The main steps involved in associating targets (REO Devices) and
initiators with each other include:
Step 1 Understanding how the targets and initiators must be identified so that
they can successfully communicate with each other.
Step 2 Making sure that IP addresses and names match on both the targets and
the initiators.
Step 3 Making another backup copy of the REO SoftKey so that your
configuration information is preserved.

Understanding How Initiators and Targets (Devices) are
Connected
To configure the REO Appliance as a backup-and-recovery-acceleration
appliance, you must provide target and initiator information. Each
volume on the REO Appliance is a target (REO Device); the servers are
initiators.
If you are using iSCSI initiators, an iSCSI name is required both at the
targets and at the initiators. An iSCSI target name is required because
it uniquely identifies a target as a storage resource for the initiators. An
iSCSI initiator name is required because it helps identify an initiator for
the purpose of target resource allocation (that is, which initiator has
access to which target resource).
If you are using FC initiators, you must provide a WWNN and WWPN for
the same purpose of providing a unique identifier.

Reviewing iSCSI Naming Conventions
iSCSI names must be unique within the domain of the end user.
However, because user domains can potentially merge with other user
domains, the iSCSI naming mechanism is structured to ensure
worldwide uniqueness. To ensure both domain and worldwide name
uniqueness, iSCSI provides for the use of different types of naming
mechanisms, based on the naming authority. Each iSCSI name is
prefixed with a short designator string that indicates the type of naming

Associating Targets (Devices) and Initiators W 87

Overland Storage REO 9000 with ProtectionPAC Software

authority. The iqn prefix is used for iSCSI-qualified names and the eui
prefix is used for Institute of Electrical and Electronics Engineers (IEEE)
iSCSI names.
To ensure the free movement of network HBAs between hosts without
carrying over the SCSI state information, iSCSI initiator names are
associated with iSCSI nodes instead of with network adapter cards. A
target name should not be tied to hardware interfaces, which can be
changed. A target name should identify the logical target and must be the
same for the target, regardless of the physical portion being addressed.

iSCSI-Qualified Names
iSCSI-qualified names are constructed in four parts, each separated by a
decimal. The first part of the name is the iqn prefix. The second part of
the name is a date code in yyyy-mm format. The third part is a reversed
domain name, and the fourth part is any string (within the character set
and length boundaries) that uniquely identifies the initiator or target.
For example, the iSCSI-qualified name iqn.200207.com.mycompany.storage:drive1 can be broken down into four
parts as shown.
Type Date
iqn

Organization Naming Authority Subgroup Naming Authority

2002-07 com.mycompany

storage:drive1

Note: To enhance ease-of-use, the REO Appliance uses more simplified
iSCSI target names.

IEEE iSCSI Names
IEEE iSCSI names are used when a manufacturer is already basing
unique identifiers on worldwide names, as defined in the SCSI SPC-2
specification (ANSI [American National Standards for Information
Systems], 2001. NCITS.351:2001. SCSI Primary Commands - 2
[SPC-2].). IEEE iSCSI names are constructed in two parts, separated by
a decimal. The first part of the name is the eui prefix. The second part of
the name is an EUI-64 address in ASCII hexadecimal (16 digits). For
example, the IEEE iSCSI name eui.02004567A425678D can be broken
down into two parts as shown.
Type EUI-64 Worldwide Name

88 X Associating Targets (Devices) and Initiators

Setup Guide

Reviewing How Targets (REO Devices) and
Initiators are Associated
After you have named the targets and initiators (described later in this
chapter), you must assign them to each other in pairs. This must be
performed both on the REO Appliance by using the REO Appliance
software console and on the application or backup server by using the
iSCSI initiator management tools. The following illustrations
demonstrate how this should be accomplished in an iSCSI configuration
using the Microsoft iSCSI initiator.
1 Match the Data Port IP address on the REO Appliance to the
target address on the backup server.
For example, if Data Port 1 on the REO Appliance is assigned an IP
address of 10.10.50.42, the IP address on the REO Appliance Network
Configuration page must match the target address on the iSCSI
configuration tool screens (you must launch the iSCSI configuration tool
to obtain this information) for the backup server you are configuring.

(To access the Add Target Portal dialog box,

2 Verify that the iSCSI Target Name on the REO Appliance
matches the target name on the backup server.
For example, if one of the volumes on the REO Appliance is named
idevice.name0, this is the iSCSI Target Name. The target name on the
REO Appliance Device Configuration page must match the target name
on the iSCSI configuration tool screens for the backup server you are
configuring.

Setup Guide

3 Match the iSCSI initiator name on the REO Appliance to the
initiator name on the backup server.
For example, if one of the volumes on the REO Appliance is named
idevice.name0, this is the iSCSI Target Name. You must assign at least
one initiator to this target (if you do not, you will not be able to access the
disk). The iSCSI initiator name on the initiator portion of the REO
Appliance Device Configuration page must match the initiator name on
the iSCSI configuration tool screen for the backup server you are
configuring.
The Initiator IP Address field is optional. If used, both the iSCSI initiator
name and the IP address will be checked by the REO Appliance and must
match for access to be granted.

Configuring Targets (REO Devices and
External Devices) and Initiators
Each disk or LUN on the REO Appliance is an iSCSI or FC target and
has a passive role in fulfilling requests initiated by the application or
backup server.
The backup server is an initiator and plays the active role in issuing
commands. An initiator is configured in conjunction with targets on the
REO Appliance as an access control mechanism. You must configure an
initiator by using the initiator software and by using the REO Appliance
console. You can assign up to eight initiators (iSCSI, FC, or a
combination of both) to each REO disk device (a virtual tape device
currently supports only one initiator) or External Device.

On each applicable server, use the management tool that came with your
iSCSI initiator to specify the target (REO Device) information.
To configure the REO Appliance as a backup-and-recovery-acceleration
appliance, you must provide target (REO Device) and initiator (host)
information. An iSCSI name (for iSCSI) or a set of WWNN and WWPN
names (for FC) is required for both the targets and the initiators. After
targets and initiators have been specified, they must be assigned to each
other. This must be performed on the server by using the software or
hardware initiator, and on the REO Appliance by using the REO
Appliance console, which you completed in the previous section.

and initiators.

100 X Working with the REO 9000

Setup Guide

Reviewing the REO Device Summary Page
The REO Device Summary page provides an immediate view of your
REO Appliance and its status. The following shows two examples of what
you might see on this page (what you see depends on how you configure
your REO Appliance).

This image shows the JBOD
configuration on an FCenabled appliance. Three of
the REO Devices have been
configured to function as
virtual LTO-2 tape devices.

This image shows the RAID 5
configuration, with logical
volumes, on an FC-enabled
appliance. The connections
have all been changed to
operate through FC. Five
logical volumes have been
created at this point.

The following explains each of the columns:

REO Device ID. This entry is automatically designated by the REO
Appliance. Depending on the configuration, you might have up to 64
IDs in this list.

iSCSI Target Name. Displays either the default name assigned by
the REO Appliance or the new name assigned by you.

FC LUN. If you purchased the FC-enabled appliance, this column
displays the LUN for each device.

Understanding the Summary Pages W 101

Status. Indicates whether the device is Up or Down. In addition to
using an Up or Down label, the color green indicates that the item is
okay, orange indicates that the item is in an unprotected state (for
example, initializing), and red indicates that the item is unavailable
(for example, a disk is missing).

Note: This status is different from that which is shown on the Physical
Volume Management page. For example, if you switch from a JBOD
configuration to a RAID 5 configuration, the status of the two device
IDs on the summary page will be Up, while the status for the two
volumes on the Physical Volume Management Page will be
INITIALIZING.

Device Type. Indicates whether the device is exported as a disk drive
or as a virtual LTO-2 tape drive. If you create a Tape Device or
Dynamic Tape Device and select the Enable Tape Compression check
box, Tape (or Dynamic Tape) appears in italic formatting in this

This chapter explains how to add one or more additional REO Appliance
appliances to expand the storage capacity in an iSCSI or FC
environment. If you are using the 12-disk version of the REO 9000 and
you subsequently purchased the additional 12-disk upgrade kit, it also
describes how to add the additional disks to the appliance.

Setting Up Additional REO Appliances in
an iSCSI Configuration
1 Install, configure, and manage each REO Appliance that you purchased
using the same instructions provided for the REO Appliance that it
complements.
Using this method, you will have multiple, independent management
consoles.
2 Enable power to the first appliance and complete the configuration
process before enabling power to the next appliance, and so on.

Expanding Storage Capacity (Scalability) W 107

Overland Storage REO 9000 with ProtectionPAC Software

Important: Because each appliance (the primary REO Appliance and
each associated REO Appliance) has its own console, change the
default values for the iSCSI Target Name fields on the REO Device
Configuration page, and change the REO Name and REO Description
fields (the default is REO) under System Information on the System
Configuration page so that all names are unique.

Change every iSCSI
Target Name, REO
Name, and REO
Description to use a
unique name.

Setting Up Additional REO Appliances in an FC
Topology
There are two options for adding additional REO Appliances to your FC

APPENDIX

Sharing Access to a REO 9000
Between Multiple Systems

The ShareDevice feature lets you share a single disk (physical or virtual)
with more than one initiator. You can use this feature with any
combination of iSCSI or FC initiator connections. However, only one
initiator can access a single disk (physical or virtual) at a time.

Note: The ShareDevice feature is currently only available on Windowsbased operating systems and is not supported for tape emulation. It
also requires that the size of the device being shared is 400 GB or
smaller.
For Windows-based initiators, the product includes a set of scripts that
helps you automate the process of sharing the disks.

Ovlndstart.exe. You can insert this file into the pre-processing script
of the backup application to suspend operation of the backup job until
the REO Appliance is ready (not in use by another server). If your preprocessing utilizes a script or batch file, make ovlndstart.exe the first
executable line in the file.

Ovlndstop.exe. You can insert this file into the post-processing script
of the backup application to flush all data from cache and then
relinquish control of the REO Appliance. If your post-processing
utilizes a script or batch file, make ovlndstop.exe the first executable
line in the file.

Important: If you do not use the scripts, you might experience errors (for
example, “Disk not ready” or “Backup device not ready”) when an
initiator attempts to access a disk that is currently being controlled by
another initiator.

Sending the Log Files to Technical Support
The REO Appliance creates and maintains log files that contain
diagnostic information intended for use by Overland Storage Technical
Support in troubleshooting issues you might encounter. The logs are
updated every 60 seconds, with new information appended to the
beginning of the applicable file. When the maximum log-file size is
reached, previous information is deleted so that new information can be
added.
To locate the logs (if requested by Technical Support)
1 Access the mapped network drive \\REO\programs, and open the logs
folder.

Open the
logs folder.

Send copies of all files.

2 Use your e-mail application to forward copies of the files to:
support@overlandstorage.com.

Tip: If the files are significant in size, consider using an application such
as WinZip to compress the logs folder and send the compressed version
of the folder instead.

Unable to Access the REO Appliance
If you cannot access the REO Appliance through the console or through
the Data Ports, try the following:
1 Check the LED lights on the REO Appliance.
If lights are not on, check all connections between the REO Appliance and
the power source.
2 Make sure that all applicable IP addresses are correct.
3 Make sure the network cables are properly installed.
The network cables must be securely attached at all connections. If the
cables appear to be properly attached but the problem persists, try
different cables.

120 X Basic Troubleshooting

Setup Guide

REO Appliance Does Not Start
If DHCP is not operational on your LAN, you must manually edit the
configuration file on the REO SoftKey before you connect it to the REO
Appliance and start it. If you already edited the configuration file or if
your LAN uses DHCP and the REO Appliance is beeping repeatedly, it
might be because a LAN cable is not connected to the Management Port,
the REO SoftKey is not inserted, the key is not inserted correctly, the key
is damaged, the copy-protection file on the key is invalid, or the wrong
key was used.
To determine why the appliance does not start
X

Choose one of the following:

If your LAN does not use DHCP and you have not edited the
configuration file on the key, perform the steps outlined under Editing
the Configuration File (for a non-DHCP or UNIX Management System)
on page 33.

If your LAN uses DHCP or if you already edited the configuration file,
do the following:

Use the software console to restart the REO Appliance. For more
information, see Powering Down the REO Appliance on page 105.

If you want a cable connected to the Management Port, make sure
that you are using the applicable type of cable and that a DHCP
server available (if the Management Port is configured for DHCP, it
will not complete the startup process until a system with DHCP is
located). Otherwise, disconnect the cable from the Management
Port.

Make sure that you are using the correct key (for example, if you
purchased more than one unit, you might have mixed up the keys).

Make sure that the key is functional by inserting it into a USB port
on your management system and verifying that you can view the
contents.

If these steps do not solve the problem, contact Customer Support
at Overland Storage. For contact information, see Customer
Support on page 159.

Internet Explorer Does Not Redirect
from IP Address on Windows Server 2003
If you access the REO Appliance console using Internet Explorer running
on Windows Server 2003, you might see a blank screen after you enter a
valid IP address for the REO Appliance to which you are trying to
connect.

This happens because Internet Explorer has an enhanced security
configuration that is enabled by default in Windows Server 2003. This
setting does not allow the server to redirect the IP address to the correct
location. To prevent this from occurring, you need to add the IP address
for the REO Appliance to the list of trusted sites for this server.
To add the REO Appliance to the list of trusted sites
1 Launch Internet Explorer.
2 In the Tools menu, click Internet Options.
3 On the Security tab, select Trusted Sites, and then click Sites.

Unable to Connect to the Disks via Windows Explorer
If you are unable to access the disks on the REO Appliance, it might be
because the system or a disk on the appliance is malfunctioning, because
the disks were reformatted using a file system other than NTFS, or
because the disks are not formatted.
1 Make sure that the REO Appliance is turned on and that all cables are
correctly connected.
2 Make sure that you can view other disks from the same initiator.
If not, there might be a problem with a cable or the Ethernet connection.
3 Make sure that you can view the targets (REO Devices) from the
initiator.

4 If you are trying to view the disks from a Windows NT system, make sure
that the disks are formatted as NTFS volumes.
The disks are factory-formatted using NTFS 4. If you reformat the disks
as another type of file system (such as FAT or FAT32), you will not be
able to access the disks using Windows NT. If you are able to view the
disks from Windows 2000 or 2003, but not from Windows NT, it indicates
that the disks are not NTFS.

Tip: To double-check the file-system property, on a Windows 2000 or
2003 system, right-click the disk, click Properties, and note the File
system designation on the General tab.

Perpetual Loop of Audio Alerts
On startup, the REO Appliance might reach an error state and begin an
endless loop of alerts. The pattern (2 beeps separated by a 1-second delay)
repeats every 4 seconds.
X

If the REO Appliance reaches this error state, turn the REO Appliance
off and then back on.
The cause of this error state might also be one of the following:

A LAN cable is not connected to the Management Port.

The REO SoftKey is not inserted, is not inserted correctly, or is
physically damaged.

The wrong REO SoftKey was used (you inserted the wrong key).

Disabling the Audio Alarm
If a power supply or fan fails or detects an issue with the appliance, an
audible alarm sounds. If you do not have the spare component needed to
correct the situation (for example, if you need to replace a power supply),
press the small, red button on the back of the appliance to turn off the
sound temporarily (after you correct the situation, make sure that you
press the button again to engage the audio feature).

Systems Restart When I Map a Disk Drive
If your systems restart whenever you try to map a disk, it indicates that
your LAN does not use DHCP, and you did not manually edit the
configuration file located on the REO SoftKey before continuing with the
configuration process.

Determining Whether a Disk Drive is Faulty
or There is a Problem with the REO Appliance
When there is a problem with a disk drive, its Status on the Physical
Volume Management page is reported on as NOT PRESENT, and the
disk moves to the FREE DRIVE POOL section (if you are using RAID 0,
all associated disks in the applicable volume also move to the FREE
DRIVE POOL section). The first step you can take is to force an addition
of the disk (JBOD only), re-creation of the volume that contains the disk
drive in question (RAID 0), rebuild of the volume that contains the disk
drive in question (RAID 5 without hot spares), or re-creation of a hot
spare (RAID 5 with hot spares). The next step is to replace the applicable
disk with a spare disk.

Forcing an Add (JBOD)
1 Make sure that none of the initiators (servers) have active connections
with the REO Appliance.
For example, in the iSCSI Initiator Properties dialog box for the
Microsoft initiator, you can check the Active Sessions tab to determine if
there is a connection that needs to be terminated.

Glossary and Acronym List

Application server. A networked computer on which production
programs are running. The programs on an application server
typically handle application interaction between an end-user’s
browser-based programs and a company’s back-end database or
business applications. (While the application server runs the
programs and processes requests, the actual programs and data are
usually stored on a file server.)
Backup server. A networked computer that actually stores copies of
files from other computers or servers or that runs backup software
that automates the backup process of moving copies of files to separate
storage medium, such as tape.
D2D. Disk-to-disk
D2D2T. Disk-to-disk-to-tape

GbE. Gigabit Ethernet
HBA. Host bus adapter
Internet SCSI (iSCSI). A standard protocol for universal access to
shared storage devices over standard, Ethernet-based transmission
control protocol/Internet protocol (TCP/IP) networks. The connectionoriented protocol transports SCSI commands, data, and status across
an IP network.
The iSCSI protocol enables block-level storage applications over TCP/
IP networks. It builds on two widely-used technologies—SCSI
commands for storage and IP protocols for networking.

iSCSI uses the SCSI command set, the core storage commands used
throughout all storage configurations.

iSCSI uses IP and Ethernet, the basis for most corporate,
metropolitan, and wide-area networks.

Glossary and Acronym List W 163

Overland Storage REO 9000 with ProtectionPAC Software

iSCSI uses standard Ethernet switches and routers to move the data
from server to storage. It also allows IP and Ethernet infrastructure to
be used for expanding access to storage area network (SAN) storage
and extending SAN connectivity across any distance.

Tip: For more information about iSCSI, se the Internet Engineering
Task Force (IETF) standards for IP storage at www.ietf.org (Internet
Society, 2002. iSCSI (Draft), www.ietf.org/internet-drafts/draft-ietfips-iscsi-13.txt).
Initiator. The client is an initiator that plays the active role in issuing
commands. In iSCSI terms, an initiator is a logical system component
(usually present in the form of a device driver) that sends SCSI I/O
commands to a target over an I/O bus or network. In this application,
the initiator accompanies the initiator software or IP storage HBA on
your application or backup server.
iSCSI target. The server is a target that plays the passive role in
fulfilling client requests. An iSCSI target is a logical system
component within an iSCSI appliance that receives SCSI I/O
commands from an initiator and executes them. A target includes one
or more logical units (LUs); each LU is a SCSI device, such as a disk
or tape drive. In this application, the target is the array of disks on the
REO Appliance.
FC. Fibre Channel
FC-AL. Fibre Channel Arbitrated Loop
FC-SW. Fibre Channel Switched
JBOD. Just a bunch of disks
LAN. Local-area network
LTO-2. Linear tape-open
LU. Logical unit
LUN. Logical unit number
LVM. Logical volume management
Mail server. A networked computer that stores and processes incoming
and outgoing e-mail.
Media server. A VERITAS Backup Exec server that runs the Backup
Exec engine. (Outside the VERITAS backup environment, a media
server usually refers to a server that handles the transmission of audio
