Chapter 2: RAID
conguration
This chapter provides instructions on setting
up, creating, and conguring RAID sets using
the available utilities.
2-2 Chapter 2: RAID conguration
2.1 Setting up RAID
The RAID card supports RAID 0, 1, 10, 5, 50, 6, and 60.
2.1.1 RAID denitions
RAID 0
(Data striping)
optimizes two identical hard disk drives to read and write
data in parallel, interleaved stacks. Two hard disks perform the same work as a
single drive but at a sustained data transfer rate, double that of a single disk alone,
thus improving data access and storage. Use of at least two new identical hard
disk drives is required for this setup.
RAID 1
(Data mirroring)
copies and maintains an identical image of data from one
drive to a second drive. If one drive fails, the disk array management software
directs all applications to the surviving drive as it contains a complete copy of
the data in the other drive. This RAID conguration provides data protection and
increases fault tolerance to the entire system. Use two new drives or use an
existing drive and a new drive for this setup. The new drive must be of the same
size or larger than the existing drive.
RAID 10 is a striped conguration with RAID 1 segments whose segments are
RAID 1 arrays. This conguration has the same fault tolerance as RAID 1, and
has the same overhead for fault-tolerance as mirroring alone. RAID 10 achieves
high input/output rates by striping RAID 1 segments. In some instances, a RAID
10 conguration can sustain multiple simultaneous drive failure. A minimum of four
hard disk drives is required for this setup.
RAID 5
stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 conguration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID
5 conguration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems. Use a
minimum of three identical hard disk drives for this setup.
RAID 50 is a combination of RAID 0 and RAID 5. It uses distributed parity and disk
striping and works best with data that requires high reliability, high request rates,
high data transfers, and medium-to-large capacity.
RAID 6 uses distributed parity, with two independent parity blocks per stripe, and
disk striping. A RAID 6 virtual drive can survive the loss of two drives without losing
data. A RAID 6 drive group, which requires a minimum of three drives, is similar to
a RAID 5 drive group. Blocks of data and parity information are written across all
drives. The parity information is used to recover the data if one or two drives fail in
the drive group.
RAID 60, a combination of RAID 0 and RAID 6, uses distributed parity, with two
independent parity blocks per stripe in each RAID set, and disk striping. A RAID 60
virtual drive can survive the loss of two drives in each of the RAID 6 sets without
losing data. It works best with data that requires high reliability, high request rates,
high data transfers, and medium-to-large capacity.
ASUS PIKE 2208 2-3
• Having RAID 0 and RAID 5 virtual disks in the same physical array is notHaving RAID 0 and RAID 5 virtual disks in the same physical array is not
recommended. If a drive in the physical array has to be rebuilt, the RAID 0
virtual disk will cause a failure during the rebuild.
• If you want to boot the system from a hard disk drive included in a created
RAID set, copy rst the RAID driver from the support CD to a oppy disk
before you install an operating system to the selected hard disk drive.
2.1.2 Installing hard disk drives
The RAID card supports SAS for RAID set conguration. For optimal performance,
install identical drives of the same model and capacity when creating a disk array.
To install SAS hard disks for RAID conguration:
1. Install the SAS hard disks into the drive bays following the instructions in the
system user guide.
2. Connect a SAS signal cable to the signal connector at the back of each drive
and to the SAS connector on the motherboard.
3. Connect a power cable to the power connector on each drive.
2-4 Chapter 2: RAID conguration
2.2 LSI WebBIOS Conguration Utility
The LSI WebBIOS Conguration Utility (CU) is an integrated RAID solution that
allows you to create RAID 0, 1, 10, 5, 50, 6, and 60 sets from SATA/SATA II/SATA
III/SAS/SAS II hard disk drives supported by the LSI 2208 6Gb/s SAS controller.
You can also use the WebBIOS CU to do the following tasks:
• Create drive groups and virtual drives for storage congurations
• Delete virtual drives
• Migrate a storage conguration to a different RAID level
• Detect conguration mismatches
• Import a foreign conguration
• Display controller, virtual drive, drive, and change parameters.
• Scan devices connected to the controller
• Initialize virtual drives
• Check congurations for data consistency
• Create a CacheCade™ conguration
• You may use disks of different sizes; however, the size of the smallest disk
determines the “logical” size of each member disk.
• DO NOT combine Serial ATA and SAS disk drives in one volume.
• The RAID setup screens shown in this section are for reference only and
may not exactly match the items on your screen due to the controller
version difference.

2.2.3 Creating a Storage Conguration
This section explains how to use the WebBIOS CU Conguration Wizard to
congure RAID arrays and virtual drives to create storage congurations.
The default settings of the conguration items mentioned in this section are
subject to change without notice, but the functions of the items will not be
affected.
Selecting the Conguration with the Conguration Wizard
Follow these steps to start the Conguration Wizard, and select a conguration
option and mode:
1. Click Conguration Wizard on
the WebBIOS main screen. The
rst Conguration Wizard screen
appears, as shown in the right
gure.
2. Select a conguration option.
If you choose the rst or second option, all existing data in the conguration
will be deleted. Make a backup of any data that you want to keep before you
choose an option.
• Clear Conguration: Clears the existing conguration.
• New Conguration: Clears the existing conguration and lets you
create a new conguration.
• Add Conguration: Retains the existing storage conguration and adds
new drives to it (this does not cause any data loss).
3. Click Next. A dialog box warns that you will lose data if you select Clear
Conguration or New Conguration.
4. On the next screen, select a conguration mode:
• Manual Conguration: Allows you to control all attributes of the new
storage conguration.
• Automatic Conguration: Automatically creates an optimal RAID
conguration.
ASUS PIKE 2208 2-9
If you select Automatic Conguration, you can choose the redundancy mode:
• Redundancy when possible: Automatically creates an optimal RAID
conguration, providing data redundancy.
• No Redundancy: Automatically creates a non-redundant RAID 0
conguration.
5. Click Next to continue.
Using Automatic Conguration
Follow these instructions to create a conguration with automatic conguration,
either with or without redundancy:
1. When WebBIOS displays the proposed new conguration, review the
information on the screen, and click Accept to accept it. (Or click Back to go
back and change the conguration.)
• RAID 0: If you selected Automatic Conguration and No
Redundancy, WebBIOS creates a RAID 0 conguration.
• RAID 1: If you selected Automatic Conguration and Redundancy
when possible, WebBIOS creates a RAID 1 conguration if only two
disk drives are available.
• RAID 6: If you selected Automatic Conguration and Redundancy
when possible, WebBIOS creates a RAID 6 conguration if three or
more disk drives are available.
2. Click Yes when you are prompted to save the conguration.
3. Click Yes when you are prompted to initialize the new virtual drive(s).
WebBIOS CU begins a background initialization of the virtual drives.
Using Manual Conguration: RAID 0
RAID 0 provides drive striping across all drives in the RAID drive group. RAID
0 does not provide any data redundancy but does offer excellent performance.
RAID 0 is ideal for applications that require high bandwidth but do not require fault
tolerance. RAID 0 also denotes an independent or single drive.
RAID level 0 is not fault-tolerant. If a drive in a RAID 0 drive group fails, the
whole virtual drive (all drives associated with the virtual drive) fails.
When you select Manual Conguration and click Next, the Drive Group Denition
screen appears. You use this screen to select drives to create drive groups.
1. Hold <Ctrl> while selecting two or more ready drives in the Drives panel on
the left until you have selected all desired drives for the drive group.
2-10 Chapter 2: RAID conguration
2. Click Add To Array to move the
drives to a proposed drive group
conguration in the Drive Groups
panel on the right, as shown in the
right gure.
3. Select a preferred power save
mode. The power save mode can
be Max, Max without cache, Auto,
None, and Controller dened. If
you need to undo the changes, click
the Reclaim button.
4. When you have nished selecting drives for the drive group, click Accept DG.
5. Click Next. The Span Denition screen appears. Select one of the available
drive groups, and then click Add to SPAN.
6. When nish, click Next. The Virtual
Drive Denition screen appears,
as shown in the right gure. Use
this screen to select the RAID level,
strip size, read policy, and other
attributes for the new virtual drives.
7. Change the virtual drive options
from the defaults listed on the
screen as needed.
Here are brief explanations of the
virtual drive options:
• RAID Level: The drop-down menu lists the possible RAID levels for the
virtual drive. Select RAID 0.
• Strip Size: The strip size species the size of the segment written to
each disk in a RAID conguration. You can set the strip size up to 1 MB.
A larger strip size produces higher read performance. If your computer
regularly performs random read requests, choose a smaller strip size.
The default is 256 KB.
• Access Policy: Select the type of data access that is allowed for this
virtual drive:
◊ RW: Allow read/write access. This is the default.
◊ Read Only: Allow read-only access.
◊ Blocked: Do not allow access.
• Read Policy: Specify the read policy for this virtual drive:
◊ No Read Ahead: This disables the read ahead capability.
ASUS PIKE 2208 2-11
◊ Always Read Ahead: This enables read ahead capability, which
allows the controller to read sequentially ahead of requested data and
to store the additional data in cache memory, anticipating that the data
will be needed soon. This speeds up reads for sequential data, but
there is little improvement when accessing random data. This is the
default.
• Write Policy: Specify the write policy for this virtual drive:
◊ Write Through: In Write Through mode, the controller sends a data
transfer completion signal to the host when the drive subsystem has
received all of the data in a transaction.
◊ Always Write Back: In Writeback mode, the controller sends a data
transfer completion signal to the host when the controller cache has
received all of the data in a transaction. This setting is recommended
in Standard mode.
• IO Policy: The IO Policy applies to reads on a specic virtual drive. It
does not affect the read ahead cache.
◊ Direct: In direct I/O mode, reads are not buffered in cache memory.
Data is transferred to the cache and the host concurrently. If the same
data block is read again, it comes from cache memory. This is the
default.
◊ Cached: In cached I/O mode, all reads are buffered in cache memory.
• Drive Cache: Specify the drive cache policy:
◊ Unchanged: Leave the current drive cache policy unchanged. This is
the default.
◊ Enable: Enable the drive cache.
◊ Disable: Disable the drive cache.
• Disable BGI: Specify the background initialization status:
◊ No: Leave background initialization enabled. This means that a new
conguration can be initialized in the background while you use
WebBIOS to do other conguration tasks. This is the default.
◊ Yes: Select Yes if you do not want to allow background initializations
for congurations on this controller.
• Select Size: Specify the size of the virtual drive in terabytes, gigabytes,
megabytes, or kilobytes. Normally, this would be the full size for RAID 0
shown in the Conguration panel on the right. You may specify a smaller
size if you want to create other virtual drives on the same drive group.
8. Click Accept to accept the changes to the virtual drive denition, or click
Reclaim to return to the previous settings.
2-12 Chapter 2: RAID conguration
9. Click Yes to conrm the write policy
mode you have chosen.
10. Click Next after you nish dening
virtual drives. The conguration
preview screen appears, as shown
in the right gure.
11. Check the information in the
conguration preview screen.
12. If the virtual drive conguration is
acceptable, click Accept to save
the conguration. Otherwise, click
Back to return to the previous screens and change the conguration.
13. If you accept the conguration, click Yes at the prompt to save the
conguration.
14. Click Yes at the prompt to start initialization.
15. After the virtual drive is successfully
created, the Manage SSD Caching
screen appears. Click Cancel to
close the sceen.
Using Manual Conguration: RAID 1
In RAID 1, the RAID controller duplicates all data from one drive to a second
drive. RAID 1 provides complete data redundancy, but at the cost of doubling the
required data storage capacity. It is appropriate for small databases or any other
environment that requires fault tolerance but small capacity.
When you select Manual Conguration and click Next, the Drive Group
Denition screen appears. Use this screen to select drives to create drive groups.
1. Hold <Ctrl> while selecting two ready drives in the Drives panel on the left.

Using Manual Conguration: RAID 10
RAID 10, a combination of RAID 1 and RAID 0, has mirrored drives. It breaks
up data into smaller blocks, then stripes the blocks of data to each RAID 1 drive
group. Each RAID 1 drive group then duplicates its data to its other drive. The size
of each block is determined by the strip size parameter. RAID 10 can sustain one
drive failure in each array while maintaining data integrity.
RAID 10 provides both high data transfer rates and complete data redundancy.
It works best for data storage that must have 100 percent redundancy of RAID
1 (mirrored drive groups) and that also needs the enhanced I/O performance of
RAID 0 (striped drive groups); it works well for medium-sized databases or any
environment that requires a higher degree of fault tolerance and moderate to
medium capacity.
When you select Manual Conguration and click Next, the Drive Group

Using Manual Conguration: RAID 5
RAID 5 uses drive striping at the block level and parity. In RAID 5, the parity
information is written to all drives. It is best suited for networks that perform a
lot of small input/output (I/O) transactions simultaneously. RAID 5 provides data
redundancy, high read rates, and good performance in most environments. It also
provides redundancy with lowest loss of capacity.
RAID 5 provides high data throughput. RAID 5 is useful for transaction processing
applications because each drive can read and write independently. If a drive fails,
the RAID controller uses the parity drive to recreate all missing information. You
can use RAID 5 for ofce automation and online customer service that require
fault tolerance. In addition, RAID 5 is good for any application that has high read
request rates but low write request rates.

Using Manual Conguration: RAID 6
RAID 6 is similar to RAID 5 (drive striping and distributed parity), except that
instead of one parity block per stripe, there are two. With two independent parity
blocks, RAID 6 can survive the loss of any two drives in a virtual drive without
losing data. Use RAID 6 for data that requires a very high level of protection from
loss.
RAID 6 is best suited for networks that perform a lot of small input/output (I/O)
transactions simultaneously. It provides data redundancy, high read rates, and
good performance in most environments.
In the case of a failure of one drive or two drives in a virtual drive, the RAID
controller uses the parity blocks to recreate all of the missing information. If two
drives in a RAID 6 virtual drive fail, two drive rebuilds are required, one for each
drive. These rebuilds do not occur at the same time. The controller rebuilds one
failed drive, and then the other failed drive.

Here are brief explanations of the virtual drive options:
• RAID Level: The drop-down menu lists the possible RAID levels for the
virtual drive. Select RAID 60.
2-28 Chapter 2: RAID conguration
• Strip Size: The strip size species the size of the segment written to
each disk in a RAID conguration. You can set the strip size up to 1 MB.
A larger strip size produces higher read performance. If your computer
regularly performs random read requests, choose a smaller strip size.
The default is 256 KB.
• Access Policy: Select the type of data access that is allowed for this
virtual drive:
◊ RW: Allow read/write access. This is the default.
◊ Read Only: Allow read-only access.
◊ Blocked: Do not allow access.
• Read Policy: Specify the read policy for this virtual drive:
◊ No Read Ahead: This disables the read ahead capability.
◊ Always Read Ahead: This enables read ahead capability, which
allows the controller to read sequentially ahead of requested data and
to store the additional data in cache memory, anticipating that the data
will be needed soon. This speeds up reads for sequential data, but
there is little improvement when accessing random data. This is the
default.
• Write Policy: Specify the write policy for this virtual drive:
◊ Write Through: In Write Through mode, the controller sends a data
transfer completion signal to the host when the drive subsystem has
received all of the data in a transaction.
◊ Always Write Back: In Writeback mode, the controller sends a data
transfer completion signal to the host when the controller cache has
received all of the data in a transaction. This setting is recommended
in Standard mode.
• IO Policy: The IO Policy applies to reads on a specic virtual drive. It
does not affect the read ahead cache.
◊ Direct: In direct I/O mode, reads are not buffered in cache memory.
Data is transferred to the cache and the host concurrently. If the same
data block is read again, it comes from cache memory. This is the
default.
◊ Cached: In cached I/O mode, all reads are buffered in cache memory.
• Drive Cache: Specify the drive cache policy:
◊ Unchanged: Leave the current drive cache policy unchanged. This is
the default.
◊ Enable: Enable the drive cache.
◊ Disable: Disable the drive cache.
• Disable BGI: Specify the background initialization status:
ASUS PIKE 2208 2-29
◊ No: Leave background initialization enabled. This means that a new
conguration can be initialized in the background while you use
WebBIOS to do other conguration tasks. This is the default.
◊ Yes: Select Yes if you do not want to allow background initializations
for congurations on this controller.
• Select Size: Specify the size of the virtual drive in terabytes, gigabytes,
megabytes, or kilobytes. Normally, this would be the full size for RAID 60
shown in the Conguration panel on the right. You may specify a smaller
size if you want to create other virtual drives on the same drive group.
15. Click Accept to accept the changes to the virtual drive denition, or click
Reclaim to undo the changes.
16. Click Yes to conrm the write policy mode you have chosen.
17. Click Next after you nish dening virtual drives. The conguration preview
screen appears.
18. Check the information in the conguration preview screen.
19. If the virtual drive conguration is acceptable, click Accept to save the
conguration. Otherwise, click Cancel to end the operation and return to the
WebBIOS main menu, or click Back to return to the previous screens and
change the conguration.
20. If you accept the conguration, click Yes at the prompt to save the
conguration.
21. Click Yes at the prompt to start initialization.
22. After the virtual drive is successfully
created, the Manage SSD Caching
screen appears. Click Cancel to
close the sceen.

2.2.6 Managing Congurations
This section includes information about maintaining and managing storage
congurations.
Running a Consistency Check
You should periodically run a consistency check on fault-tolerant virtual drives. A
consistency check veries that the redundancy data is correct and available for
RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 arrays. To do this, follow
these steps:
1. On the main WebBIOS CU screen, select a virtual drive.
2. When the Virtual Drive screen appears, select CC in the lower left panel, and
click Go.
3. Click Yes to continue. The consistency check begins.
If the WebBIOS CU nds a difference between the data and the parity value on
the redundant drive group, it assumes that the data is accurate and automatically
corrects the parity value. Be sure to back up the data before running a consistency
check if you think the data may be corrupted.
Deleting a Virtual Drive
You can delete any virtual drive on the controller if you want to reuse that space for
a new virtual drive. The WebBIOS CU provides a list of congurable drive groups
where there is a space to congure. If multiple virtual drives are dened on a single
drive group, you can delete a virtual drive without deleting the whole drive group.
Back up any data that you want to keep before you delete the virtual drive.
To delete a virtual drive, follow these steps:
1. On the main WebBIOS CU screen, select a virtual drive.
2. When the Virtual Drive screen appears, select Delete in the bottom panel
under the heading Operations, and click Go.
3. When the message appears, conrm that you want to delete the virtual drive.
ASUS PIKE 2208 2-39
Importing or Clearing a Foreign Conguration
A foreign conguration is a storage conguration that already exists on a
replacement set of drives that you install in a computer system. In addition, if one
or more drives are removed from a conguration, by a cable pull or drive removal,
for example, the conguration on those drives is considered a foreign conguration
by the RAID controller.
The WebBIOS CU allows you to import the foreign conguration to the RAID
controller, or to clear the conguration so you can create a new conguration using
these drives.
When you create a new conguration, the WebBIOS CU shows only the
uncongured drives. Drives that have existing congurations, including foreign
congurations, do not appear. To use drives with existing congurations, you
must rst clear the conguration on those drives.
Foreign conguration(s) found on adapter
Press any key to continue or ‘C‘ to load the conguration utility,
or ‘F‘ to import foreign conguration(s) and continue.
If WebBIOS CU detects a foreign conguration, the following screen appears when
enter the WebBIOS CU.
If a foreign conguration is detected during POST, press <C> when the following
screen appears.
Follow these steps to import or clear a foreign conguration:
1. Click the drop-down list to show the congurations.
The GUID (Global Unique Identier) entries on the drop-down list are OEM
names and will vary from one installation to another.
1 Virtual Drive(s) handled by BIOS
Press <Ctrl><H> for WebBIOS or press <Ctrl><Y> for Preboot CLI
When the following screen appears, press <Ctrl+H> to enter the WebBIOS CU.

3. Perform one of the following steps:
• Click Preview to preview
the foreign congurations.
The Foreign Conguration
Preview screen appears, as
shown in the right gure.
• Click Clear to clear the foreign
congurations and reuse the
drives for another virtual drive.
If you click Cancel, it cancels the
importation or preview of the foreign
conguration.
The right panel shows the virtual drive properties of the foreign conguration.
In this example, there are two RAID1 virtual drives with 67.843GB each. The
left panel shows the drives in the foreign conguration.
4. Click Import to import this foreign conguration(s) and use it on this
controller.
Foreign Configurations in Cable Pull and Drive Removal Scenarios
If one or more drives are removed from a conguration, by a cable pull or
drive removal, for example, the conguration on those drives is considered a
foreign conguration by the RAID controller.
Use the Foreign Conguration Preview screen to import or clear the
foreign conguration in each case.
The following scenarios can occur with cable pulls or physical drive removals.
If you want to import the foreign conguration in any of the following scenarios,
you should have all the drives in the enclosure before you perform the import
operation.
1. Scenario #1: If all of the drives in a conguration are removed
and re-inserted, the controller considers the drives to have foreign
congurations.
Import or clear the foreign conguration. If you select Import, automatic
rebuilds will occur in redundant virtual drives.
Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual drives.
2. Select a conguration or All Congurations.
ASUS PIKE 2208 2-41
2. Scenario #2: If some of the drives in a conguration are removed
and re-inserted, the controller considers the drives to have foreign
congurations.
Import or clear the foreign conguration. If you select Import, automatic
rebuilds will occur in redundant virtual drives.
Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual drives.
3. Scenario #3: If all the drives in a virtual drive are removed, but at
different times, and re-inserted, the controller considers the drives to
have foreign congurations.
Import or clear the foreign conguration. If you select Import, all drives
that were pulled before the virtual drive became ofine will be imported
and then automatically rebuilt. Automatic rebuilds will occur in redundant
virtual drives.
4. Scenario #4: If the drives in a non-redundant virtual drive are removed,
the controller considers the drives to have foreign congurations.
Import or clear the foreign conguration. No rebuilds will occur after
the import operation because there is no redundant data to rebuild the
drives with.

3.1 RAID driver installation
After creating the RAID sets for your server system, you are now ready to install
an operating system to the independent hard disk drive or bootable array. This part
provides instructions on how to install or update the RAID card drivers.
The RAID card driver might be included in the Linux OS installation CD, and
could be loaded automatically during OS installation. However, we recommend
using the RAID driver packaged in the RAID card support CD for better
reliability.
Creating a RAID driver disk
You may have to use another system to create the RAID driver disk from the
RAID card support CD or from the Internet.
A oppy disk with the RAID driver is required when installing Windows® Server
2003 or Linux operating system on a hard disk drive that is included in a RAID set.
You can create a RAID driver disk in DOS (using the Makedisk application in the
support CD).
To create a RAID driver disk in DOS environment:
1. Place the RAID card support CD in the optical drive.
2. Restart the computer, then enter the BIOS Setup.
3. Select the optical drive as the rst boot priority to boot from the support CD.
Save your changes, then exit the BIOS Setup.
4. Restart the computer.
5. The Make Disk menu appears. SelectThe Make Disk menu appears. Select PIKE 2208 SAS2 card Driver, and press
