About the SCv3000 and SCv3020 Storage System

Switches
Dell offers enterprise-class switches as part of the total Storage Center solution.
The SCv3000 and SCv3020 storage system supports Fibre Channel (FC) and Ethernet switches, which provide robust connectivity to servers and allow for the use of redundant transport paths. Fibre Channel (FC) or Ethernet switches can provide connectivity to a remote Storage Center to allow for replication of data. In addition, Ethernet switches provide connectivity to a management network to allow configuration, administration, and management of the Storage Center.
Storage Center Communication
A Storage Center uses multiple types of communication for both data transfer and administrative functions.
Storage Center communication is classified into three types: front end, back end, and system administration.
Front-End Connectivity
Front-end connectivity provides I/O paths from servers to a storage system and replication paths from one Storage Center to another Storage Center. The SCv3000 and SCv3020 storage system provides the following types of front-end connectivity:
� Fibre Channel � Hosts, servers, or network-attached storage (NAS) appliances access storage by connecting to the storage system Fibre Channel ports through one or more Fibre Channel switches. Connecting host servers directly to the storage system, without using Fibre Channel switches, is not supported.
� iSCSI � Hosts, servers, or network-attached storage (NAS) appliances access storage by connecting to the storage system iSCSI ports through one or more Ethernet switches. Connecting host servers directly to the storage system, without using Ethernet switches, is not supported.
When replication is licensed, the SCv3000 and SCv3020 storage system can use the front-end Fibre Channel or iSCSI ports to replicate data to another Storage Center
Fault Domains for SCv3000 Series Storage Systems
The Storage Center handles all fault domain creation and modification on SCv3000 series storage systems.
Depending on the hardware configuration, the following fault domains are automatically created on SCv3000 series storage systems:
� For SCv3000 series storage systems with Fibre Channel HBAs, two fault domains are created for the Fibre Channel ports. � For SCv3000 series storage systems with iSCSI HBAs, two fault domains are created for the iSCSI ports. � For SCv3000 series storage systems with SAS HBAs, four fault domains are created for the SAS ports. � For SCv3000 series storage systems with iSCSI mezzanine cards, two fault domains are created for the iSCSI ports. � For SCv3000 series storage systems with iSCSI mezzanine cards and iSCSI HBAs, four fault domains are created for iSCSI ports
NOTE: Additional front-end fault domains cannot be created on SCv3000 series storage systems. In addition, existing fault domains cannot be modified or deleted on SCv3000 series storage systems.

CAUTION: To reduce the risk of damage to the equipment, do not use excessive force when inserting the transceiver module. 3. Position the fiber-optic cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the transceiver module. CAUTION: Touching the end of a fiber-optic cable damages the cable. Whenever a fiber-optic cable is not connected, replace the protective covers on the ends of the cable. 4. Insert the fiber-optic cable into the transceiver module until the latching mechanism clicks.
Remove an SFP+ Transceiver Module
Complete the following steps to remove an SFP+ transceiver module from a storage controller.
Prerequisites Use failover testing to make sure that the connection between host servers and the Storage Center remains up if the port is disconnected.
About this task Read the following cautions and information before beginning the removal and replacement procedures.
NOTE: To reduce the risk of injury from laser radiation or damage to the equipment, take the following precautions:
� Do not open any panels, operate controls, make adjustments, or perform procedures to a laser device other than those specified in this document.
� Do not stare into the laser beam.
CAUTION: Transceiver modules can be damaged by electrostatic discharge (ESD). To prevent ESD damage to the transceiver module, take the following precautions:
� Wear an antistatic discharge strap while handling modules. � Place modules in antistatic packing material when transporting or storing them.
Steps 1. Remove the fiber-optic cable that is inserted into the transceiver.
a) Make sure the fiber-optic cable is labeled before removing it. b) Press the release clip on the bottom of the cable connector to remove the fiber-optic cable from the transceiver.
CAUTION: Touching the end of a fiber-optic cable damages the cable. Whenever a fiber-optic cable is not connected, replace the protective covers on the ends of the cables.

Back-End Connectivity
Back-end connectivity is strictly between the storage system and expansion enclosures. The SCv3000 and SCv3020 storage system supports back-end connectivity to multiple SCv300, SCv320, and SCv360 expansion enclosures.
System Administration
To perform system administration, the Storage Center communicates with computers using the Ethernet management (MGMT) port on the storage controllers. The Ethernet management port is used for Storage Center configuration, administration, and management.
Storage Center Replication
Storage Center sites can be collocated or remotely connected and data can be replicated between sites. Storage Center replication can duplicate volume data to another site in support of a disaster recovery plan or to provide local access to a remote data volume. Typically, data is replicated remotely as part of an overall disaster avoidance or recovery plan. The SCv3000 and SCv3020 storage system supports replication to the storage systems listed below. However, a Storage Manager Data Collector must be used to replicate data between the storage systems. For more information about installing and managing the Data Collector and setting up replications, see the Storage Manager Installation Guide. � SCv3000 series � SC4020 � SC5020 series � SC7020 series � SC8000 � SC9000

About the SCv3000 and SCv3020 Storage System

Power Supply and Cooling Fan Modules
The SCv3000 and SCv3020 storage system supports two hot-swappable power supply/cooling fan modules. The cooling fans and the power supplies are integrated into the power supply/cooling fan module and cannot be replaced separately. If one power supply/cooling fan module fails, the second module continues to provide power to the storage system.
NOTE: When a power supply/cooling fan module fails, the cooling fan speed in the remaining module increases significantly to provide adequate cooling. The cooling fan speed decreases gradually when a new power supply/cooling fan module is installed.
CAUTION: A single power supply/cooling fan module can be removed from a powered on storage system for no more than 90 seconds. If a power supply/cooling fan module is removed for longer than 90 seconds, the storage system might shut down automatically to prevent damage.

Safety Precautions
Always follow these safety precautions to avoid injury and damage to Storage Center equipment.
If equipment described in this section is used in a manner not specified by Dell, the protection provided by the equipment could be impaired. For your safety and protection, observe the rules described in the following sections.
NOTE: See the safety and regulatory information that shipped with each Storage Center component. Warranty information is included within this document or as a separate document.

Installation Safety Precautions
Follow these safety precautions:

Install the Storage Center Hardware

� Dell recommends that only individuals with rack-mounting experience install the storage system in a rack. � Make sure the storage system is always fully grounded to prevent damage from electrostatic discharge. � When handling the storage system hardware, use an electrostatic wrist guard (not included) or a similar form of protection.
The chassis must be mounted in a rack. The following safety requirements must be considered when the chassis is being mounted:
� The rack construction must be capable of supporting the total weight of the installed chassis. The design should incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.
� When loading a rack with chassis, fill from the bottom up; empty from the top down. � To avoid danger of the rack toppling over, slide only one chassis out of the rack at a time.
Electrical Safety Precautions
Always follow electrical safety precautions to avoid injury and damage to Storage Center equipment.
NOTE: Disconnect power from the storage system when removing or installing components that are not hot-swappable. When disconnecting power, first power down the storage system using the Storage Manager and then unplug the power cords from all the power supplies in the storage system.
� Provide a suitable power source with electrical overload protection. All Storage Center components must be grounded before applying power. Make sure that a safe electrical earth connection can be made to power supply cords. Check the grounding before applying power.
� The plugs on the power supply cords are used as the main disconnect device. Make sure that the socket outlets are located near the equipment and are easily accessible.
� Know the locations of the equipment power switches and the room's emergency power-off switch, disconnection switch, or electrical outlet.
� Do not work alone when working with high-voltage components. � Use rubber mats specifically designed as electrical insulators. � Do not remove covers from the power supply unit. Disconnect the power connection before removing a power supply from the
storage system. � Do not remove a faulty power supply unless you have a replacement model of the correct type ready for insertion. A faulty power
supply must be replaced with a fully operational module power supply within 24 hours. � Unplug the storage system chassis before you move it or if you think it has become damaged in any way. When powered by multiple
AC sources, disconnect all power sources for complete isolation.
Electrostatic Discharge Precautions
Always follow electrostatic discharge (ESD) precautions to avoid injury and damage to Storage Center equipment.
Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. The resulting electrical discharge can damage electronic components and printed circuit boards. Follow these guidelines to protect your equipment from ESD:
� Dell recommends that you always use a static mat and static strap while working on components in the interior of the chassis. � Observe all conventional ESD precautions when handling plug-in modules and components. � Use a suitable ESD wrist or ankle strap. � Avoid contact with backplane components and module connectors. � Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.
General Safety Precautions
Always follow general safety precautions to avoid injury and damage to Storage Center equipment.
� Keep the area around the storage system chassis clean and free of clutter. � Place any system components that have been removed away from the storage system chassis or on a table so that they are not in the
way of other people. � While working on the storage system chassis, do not wear loose clothing such as neckties and unbuttoned shirt sleeves. These items
can come into contact with electrical circuits or be pulled into a cooling fan. � Remove any jewelry or metal objects from your body. These items are excellent metal conductors that can create short circuits and
harm you if they come into contact with printed circuit boards or areas where power is present. � Do not lift the storage system chassis by the handles of the power supply units (PSUs). They are not designed to hold the weight of
the entire chassis, and the chassis cover could become bent.

Install the Storage Center Hardware

� Before moving the storage system chassis, remove the PSUs to minimize weight. � Do not remove drives until you are ready to replace them.
NOTE: To ensure proper storage system cooling, hard drive blanks must be installed in any hard drive slot that is not occupied.
Prepare the Installation Environment
Make sure that the environment is ready for installing the Storage Center. � Rack Space -- The rack must have enough space to accommodate the storage system chassis, expansion enclosures, and switches. � Power -- Power must be available in the rack, and the power delivery system must meet the requirements of the Storage Center. AC
input to the power supply is 200�240 V. � Connectivity -- The rack must be wired for connectivity to the management network and any networks that carry front-end I/O
from the Storage Center to servers.
Install the Storage System in a Rack
Install the storage system and other Storage Center system components in a rack.
About this task Mount the storage system and expansion enclosures in a manner that allows for expansion in the rack and prevents the rack from becoming top-heavy. The SCv3000 and SCv3020 storage system ships with a ReadyRails II kit. The rails come in two different styles: tool-less and tooled. Follow the detailed installation instructions located in the rail kit box for your particular style of rails.
NOTE: Dell recommends using two people to install the rails, one at the front of the rack and one at the back.
Steps 1. Position the left and right rail end pieces labeled FRONT facing inward. 2. Align each end piece with the top and bottom holes of the appropriate U space.

Figure 27. Attach the Rails to the Rack 3. Engage the back end of the rail until it fully seats and the latch locks into place. 4. Engage the front end of the rail until it fully seats and the latch locks into place. 5. Align the system with the rails and slide the storage system into the rack.

Connect the Front-End Cabling
Front-end cabling refers to the connections between the storage system and external devices such as host servers or another Storage Center. Dell recommends connecting the storage system to host servers using the most redundant option available. Also, ensure that the speed of the HBAs in the storage controller matches the speed of the host server. � For a list of supported HBAs and detailed host adapter settings, see the Dell EMC Storage Compatibility Matrix. � For detailed switch configurations, see the Switch Configuration Guides for SC Series.
Topics:
� Types of Redundancy for Front-End Connections � Connecting to Host Servers with Fibre Channel HBAs � Connecting to Host Servers with iSCSI HBAs or Network Adapters � Connecting to Host Servers with SAS HBAs � Attach Host Servers (Fibre Channel) � Attach the Host Servers (iSCSI) � Attach the Host Servers (SAS) � Connect the Management Ports to the Management Network
Types of Redundancy for Front-End Connections
Front-end redundancy is achieved by eliminating single points of failure that could cause a server to lose connectivity to the Storage Center. Depending on how the Storage Center is cabled and configured, the following types of redundancy are available.
Port Redundancy
If a port becomes unavailable because it is disconnected or a hardware failure has occurred, the port moves over to another port in the same fault domain.
Storage Controller Redundancy
To allow for storage controller redundancy, a front-end port on each storage controller must be connected to the same switch or server. If a storage controller becomes unavailable, the front-end ports on the offline storage controller move over to the ports (in the same fault domain) on the available storage controller.
Multipath I/O (MPIO)
MPIO allows a server to use multiple paths for I/O if they are available. MPIO software offers redundancy at the path level. MPIO typically operates in a round-robin manner by sending packets first down one path and then the other. If a path becomes unavailable, MPIO software continues to send packets down the functioning path.
NOTE: MPIO is operating-system specific, and it loads as a driver on the server or it is part of the server operating system.
MPIO Behavior
The server must have at least two FC or iSCSI ports to use MPIO. When MPIO is configured, a server can send I/O to multiple ports on the same storage controller.

Connect the Front-End Cabling

MPIO Configuration Instructions for Host Servers

If a Storage Manager wizard is used to configure host server access to the Storage Center, the Storage Manager attempts to automatically configure MPIO with best practices.
NOTE: Compare the host server settings applied by the Storage Manager wizard against the latest Storage Center Best Practices documents (listed in the following table) on the Dell TechCenter site (http://en.community.dell.com/ techcenter/storage/).

Connecting to Host Servers with Fibre Channel HBAs
A storage system with Fibre Channel front-end ports connects to one or more FC switches, which connect to one or more host servers with Fibre Channel HBAs.

Fibre Channel Zoning
When using Fibre Channel for front-end connectivity, zones must be established to ensure that storage is visible to the servers. Use the zoning concepts discussed in this section to plan the front-end connectivity before starting to cable the storage system.
Dell recommends creating zones using a single initiator host port and multiple Storage Center ports.
WWN Zoning Guidelines
When WWN zoning is configured, a device may reside on any port, or change physical ports and still be visible, because the switch is seeking a WWN.
List of guidelines for WWN zoning.
� Include all Storage Center virtual World Wide Port Names (WWPNs) in a single zone. � Include all Storage Center physical World Wide Port Names (WWPNs) in a single zone. � For each host server HBA port, create a zone that includes the HBA port WWPN and multiple Storage Center virtual WWPNs on the
same switch. � For Fibre Channel replication from Storage Center system A to Storage Center system B:
� Include all Storage Center physical WWPNs from system A and system B in a single zone. � Include all Storage Center physical WWPNs of system A and the virtual WWPNs of system B on the particular fabric. � Include all Storage Center physical WWPNs of system B and the virtual WWPNs of system A on the particular fabric.
NOTE: Some ports may not be used or dedicated for replication, however ports that are used must be in these zones.

Fibre Channel Replication
Storage Center System A (Virtual Port Mode) to Storage Center System B (Virtual Port Mode)
� Include all Storage Center physical WWPNs from system A and system B in a single zone. � Include all Storage Center physical WWPNs of system A and the virtual WWPNs of system B on the particular fabric. � Include all Storage Center physical WWPNs of system B and the virtual WWPNs of system A on the particular fabric.

Connect the Back-End Cabling
Back-end cabling refers to the connections between the storage system and expansion enclosures. An SCv3000 and SCv3020 storage system can be deployed with or without expansion enclosures.
NOTE: When expansion enclosures are not used, there is no need to interconnect the SAS port of a storage controller.
Topics:
� Expansion Enclosure Cabling Guidelines � Back-End Connections to Expansion Enclosures � Label the Back-End Cables � Attach the Serial Cable
Expansion Enclosure Cabling Guidelines
The connection between a storage system and expansion enclosures is referred to as a SAS chain. A SAS chain is made up of two paths, which are referred to as the A side and B side. Each side of the SAS chain starts at a SAS port on one storage controller and ends at a SAS port the other storage controller. You can connect multiple expansion enclosures to an SCv3000 and SCv3020 by cabling the expansion enclosures in series. However, the SCv3000 and SCv3020 do not support the cabling of SCv300 and SCv320 expansion enclosures on the same SAS chain as SCv360 expansion enclosures. You can connect multiple expansion enclosures to an SCv3000 and SCv3020 by cabling the expansion enclosures in series. However, the SCv3000 and SCv3020 does not support the cabling of SCv300 and SCv320 Expansion Enclosures on the same SAS chain as SCv360 expansion enclosures.
Back-End SAS Redundancy
Use redundant SAS cabling to make sure that an unavailable I/O port or storage controller does not cause a Storage Center outage. If an I/O port or storage controller becomes unavailable, the Storage Center I/O continues on the redundant path.
Back-End Connections to Expansion Enclosures
The SCv3000 and SCv3020 supports up to 16 SCv300 expansion enclosures, up to eight SCv320 expansion enclosures, and up to three SCv360 expansion enclosures per SAS chain. The following sections show common cabling between the SCv3000 and SCv3020 and expansion enclosures. Locate the scenario that most closely matches the Storage Center that you are configuring and follow the instructions, modifying them as necessary.

Deploy the Storage Center
Storage Center can be deployed using different methods, including the web-based Unisphere or the Storage Manager Client.
Topics:
� Preparing for Deployment � Deploying the Storage Center Using Unisphere � Unisphere Discovery Utility � Deploying the Storage Center Using Storage Manager Client
Preparing for Deployment
Before starting the Storage Center deployment, review the IPv address information below, cable and power on the system, and collect the required information.
IPv Addresses
The configuration process uses DHCP to obtain IPv4 and IPv6 addresses from the data center network. If DHCP is not available: � Configure the IPv4 address on the system running the Storage Manager client on the target subnet, and � Enable IPv6 addressing. This allows the discovery and initial configuration to occur over the IPv6 link local address and then transition to the IPv4 address when the controller IP addresses are configured. If IPv6 is not allowed or is blocked, configure the Storage Manager client's NIC with two IPv4 IP addresses: � One IPv4 address configured on the target subnet � A second IPv4 address on the link local subnet, such as 169.254.10.10 This allows the discovery and initial configuration to occur over the IPv4 link local address and then transition to the IPv4 address when the controller IP addresses are configured.
Connect Power Cables and Turn On the Storage System
Connect power cables to the storage system components and turn on the hardware.
About this task � If the storage system is installed without expansion enclosures, connect power cables to the storage system chassis and turn on the
storage system. � If the storage system is installed with expansion enclosures, connect power cables to the expansion enclosure chassis. Make sure you
power on each expansion enclosure before turning on the storage system. NOTE: When powering on expansion enclosures with spinning hard drives, wait approximately three minutes for the drives to spin up before powering on the storage system.
Steps 1. Make sure that the power switches are in the OFF position before connecting the power cables. 2. Connect the power cables securely to both power supply/cooling fan modules in the storage system chassis.

� Troubleshooting Storage Controllers � Troubleshooting Hard Drives � Troubleshooting Expansion Enclosures
Troubleshooting Storage Controllers
To troubleshoot storage controllers:
Steps 1. Check the status of the storage controller using Storage Manager. 2. Check the position of the storage controllers. 3. Check the pins and reseat the storage controller.
a) Remove the storage controller. b) Verify that the pins on the storage system backplane and the storage controller are not bent. c) Reinstall the storage controller. 4. Determine the status of the storage controller link status indicators. If the indicators are not green, check the cables. a) Shut down the storage controller. b) Reseat the cables on the storage controller. c) Restart the storage controller. d) Recheck the link status indicators. If the link status indicators are not green, replace the cables.
Troubleshooting Hard Drives
To troubleshoot hard drives:
Steps 1. Check the status of the hard drive using Storage Manager. 2. Determine the status of the hard drive indicators.
� If the hard drive status indicator blinks amber ON for two seconds and OFF for one second, the hard drive has failed. � If the hard drive status indicator is not lit, proceed to the next step. 3. Check the connectors and reseat the hard drive.
CAUTION: Perform this step only on unmanaged drives or after you confirm that the particular drive contains no user data. The Fault LED alone is not an indication that you can safely remove the drive.
a) Remove the hard drive. b) Check the hard drive and the backplane to ensure that the connectors are not damaged. c) Reinstall the hard drive. Make sure the hard drive makes contact with the backplane.

Troubleshooting Expansion Enclosures
To troubleshoot expansion enclosures:
Steps 1. Check the status of the expansion enclosure using Storage Manager. 2. If an expansion enclosure and/or drives are missing from the Storage Manager, you might need to check for and install Storage Center
updates to use the expansion enclosure and/or drives. 3. If an expansion enclosure firmware update fails, check the back-end cabling and ensure that redundant connections are used.
