Fault domains provide fault tolerance at the storage controller level. Dell recommends using redundant cabling to avoid a single point of failure.

1. Identify the protocol being used to connect the host servers to the disk array.

2. Refer to the diagram below that corresponds to the proper protocol. These cabling guidelines ensure the configuration has redundancy and failover capability.

Setting Up Your Dell SCv3000 and SCv3020 Storage System (iSCSI Front End)

Warning! Before you set up and operate your Dell storage system, review the safety

instructions that came with your storage system.

Warning! The chassis is heavy. Do not attempt to lift

the chassis without assistance.

Use the racking instructions included with your package to mount the chassis.

Mount the storage system chassis and expansion enclosures in a manner that allows

for expansion in the rack and prevents the rack from becoming top-heavy. Secure the

storage system chassis to the rack using the mounting screws that are located behind

the latches on each chassis ear. Dell recommends mounting the storage system chassis

in the bottom of the rack.

1 2Before You Begin Mount the Chassis and Optional Enclosures

Unpack Storage Center Equipment

A Dell SCv3000 series storage system includes:

• Documentation

• Storage system

• Front bezel

• Rack rails

• Power cables (2)

• USB cables (2)

Develop a Configuration Plan

Before installing the storage hardware, develop a configuration plan where you can record host

server information, switch information, and network information.

Record System Information

• System management IPv4 address for Storage Center

• IPv4 address of the MGMT port on each storage controller

• Domain name

• DNS server address

Consider Plans for Multipath/Failover

Redundancy is provided by fault domains, which allow alternate paths if a path fails. Fault

domains are determined by the number of independent fabrics. Each switch carries a separate

fault domain. If a port fails, any port within the same fault domain takes over for the failed port.

Dell recommends using multipathing, so that volumes are mapped to ports in more than one fault

domain.

More Information

For operating system, NIC or iSCSI host bus adapter (HBA), and switch requirements, refer to

the Dell Storage Compatibility Matrix on the Dell Tech Center at http://en.community.dell.com/

techcenter/storage.

4Cable the Host Servers to the Storage System

1. Hold the bezel with the logo upright.

2. Hook the right end of the bezel into the right side of the chassis.

3. Swing the left end of the bezel toward the left side of the chassis.

4. Press the bezel into place until the release latch closes.

5. Use the key to lock the front bezel.

3Install the Bezel

5Connect to Management Network

The Ethernet management interface of each storage controller must be connected to a management

network. The Ethernet management port provides access to the Storage Center and is used to send emails,

alerts, SNMP traps, and support data.

1. Connect the Ethernet management port on the top storage controller to the Ethernet switch.

2. Connect the Ethernet management port on bottom storage controller to the Ethernet switch.

Setting Up Your Dell SCv3000 and SCv3020 Storage System (iSCSI Front End)

To add capacity to your storage system, you can connect up to sixteen SCv300, eight SCv320, or two SCv360 expansion enclosures to an SCv3000 series storage system. A maximum of 222 physical disks are supported in an SCv3000

series storage system.

Each expansion enclosure includes two Enclosure Management Modules (EMM) in two interface slots.

NOTE: If the storage system is installed without expansion enclosures, do not interconnect the back-end SAS ports on the storage controllers.

1. Power on any network switches, routers, or other standalone

components.

2. Power on any expansion enclosures that might be a part of the system.

3. Power on the storage system by turning on both power supply/cooling

fan modules.

The Dell Storage Manager Client provides access to the initial setup wizards. The wizards help you remotely discover and configure

storage systems and configure connected host servers.

NOTE: The initial setup wizards are only supported on 64-bit operating systems.

Install and Start the Dell Storage Manager Client

1. Log in to the Dell Digital Locker at www.dell.com/support/software, register your storage system, and download the Windows or

Linux version of the Dell Storage Manager Client.

2. Install the Dell Storage Manager Client on the host server. To discover and configure a Storage Center, the software must be installed

on a host server that is located on the same subnet as the storage system. For host setup, the client does not have to be on the

same subnet as the storage system.

3. To start the software on a Windows computer, right-click on the Dell Storage Manager Client shortcut and select Run as

administrator.

To start the software on a Linux computer, execute the command ./Client from the var/lib/dell/bin directory. The Dell

Storage Manager Client welcome screen opens.

Discover and Configure Storage Center Wizard

1. Click the Discover and Configure Uninitialized Storage Centers link. The Discover and Configure Storage Center wizard opens.

2. Follow the steps in the wizard to discover and configure uninitialized Storage Centers.

NOTE: If the wizard does not discover the Storage Center, refer to the Dell SCv3000 and SCv3020 Storage System

Deployment Guide for additional methods to deploy the Storage Center.

10 Attach the Host Servers

Refer to the Dell Storage Compatibility Matrix for a list of supported iSCSI network adapters.

Windows and Linux Hosts

Install the iSCSI HBAs or network adapters, install the drivers, and make sure that the latest supported BIOS

is installed.

1. Install the iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers.

2. Install supported iSCSI HBA drivers and make sure that iSCSI HBAs have the latest supported firmware.

3. Use the iSCSI cabling diagrams to cable the host servers to switches. Connecting host servers directly

to the storage system without using Ethernet switches is not supported.

4. Assign IP addresses to each iSCSI port to match the subnets for each fault domain.

CAUTION: Make sure to assign the correct IP addresses to the HBAs or network adapters. Assigning IPs

to the wrong ports can cause connectivity issues.

NOTE: If using jumbo frames, enable and configure jumbo frames on all devices in the data path.

VMware ESXi Hosts

Install the iSCSI HBAs or network adapters (NICs) and make sure that the latest supported BIOS is installed.

1. Install the iSCSI HBAs or NICs dedicated for iSCSI traffic in the ESXi hosts.

2. Use the iSCSI cabling diagrams to cable the ESXi hosts to switches. Connecting ESXi hosts directly to the

storage system without using Ethernet switches is not supported.

3. Create a VMkernel port for each iSCSI HBA or NIC to be used for iSCSI.

4. Assign IP addresses for each adapter port to match the subnets for each fault domain.

CAUTION: Make sure to assign the correct IP addresses to the HBAs or network adapters. Assigning IPs

to the wrong ports can cause connectivity issues.

NOTE: If using jumbo frames, enable and configure jumbo frames on all devices in the data path: adapter

ports, switches, and storage system.

5. If using the software iSCSI initiator and the server has iSCSI offload, the iSCSI hardware initiator must be

disabled.

6. If using iSCSI HBAs, configure Network Port Binding to add the VMkernel ports to the iSCSI

Storage Adapter. Do not bind NICs to the software initiator.

7. If using software iSCSI initiator, add the Storage Center's iSCSI target IPs to the Dynamic Discovery.
