Install the Fibre Channel or iSCSI HBAs in the host servers and connect the host servers and storage

system to the corresponding Fibre Channel or Ethernet switches.

Fibre Channel 4 Port Configuration

iSCSI 4 Port Configuration

1. For Fibre Channel 4 Port configurations, install Fibre

Channel HBAs into the host servers.

For iSCSI 4 Port configurations, install iSCSI HBAs or

network interface controllers (NICs) dedicated for iSCSI

traffic into the host servers.

– Top storage controller: port 4 to switch 2

– Bottom storage controller: port 2 to switch 2

– Bottom storage controller: port 4 to switch 2

Fibre Channel 2 Port Configuration

iSCSI 2 Port Configuration

1. For Fibre Channel 2 Port configurations, install Fibre

Channel HBAs into the host servers.

Setting Up a Dell SC5020 and SC5020F Storage System

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

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

An SC5020 and SC5020F storage system includes:

• Documentation

• Storage system with drives

• Rack rails

• USB cables (2)

• Power cables (2)

• Front bezel

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

• Additional IPv4 addresses if the storage system has iSCSI I/O ports

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 Fibre Channel fabrics or iSCSI networks.

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, 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.

The SC5020 storage system supports Fibre Channel, iSCSI, or SAS protocols to connect the Storage Center to host servers. The SC5020F storage system supports Fibre Channel or iSCSI protocols to connect the Storage Center to host servers.

Fault domains provide fault tolerance at the storage controller level. If you are using Fibre Channel, incorporate your switch zoning strategy with the fault domains. 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 storage system.

2. Refer to the diagram below that corresponds to the proper protocol. These cabling guidelines ensure the configuration has redundancy and failover capability. For more information, contact Dell Technical Support.

Cable 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.

Install the Front Bezel

SAS HBA Cabling

Install the SAS HBAs in the host servers and directly connect the

host servers to the storage system.

NOTE: The SC5020F storage system does not support

front-end SAS connectivity.

SAS 4 Port Configuration

1. Install SAS HBAs in the host servers.

2. Connect fault domain 1 (in orange) to server 1.

– Top storage controller: port 1 to port on server 1

– Bottom storage controller: port 1 to port on server 1

3. Connect fault domain 2 (in blue) to server 2.

– Top storage controller: port 2 to port on server 2

– Bottom storage controller: port 2 to port on server 2

4. Connect fault domain 3 (in gray) to server 3.

– Top storage controller: port 3 to port on server 3

– Bottom storage controller: port 3 to port on server 3

5. Connect fault domain 4 (in red) to server 4.

– Top storage controller: port 4 to port on server 4

– Bottom storage controller: port 4 to port on server 4

iSCSI Mezzanine Card Cabling

If the storage system includes an iSCSI mezzanine card, connect the

host servers and storage system to Ethernet switches.

iSCSI 4 Port Mezzanine Card Configuration

1. Connect each host server to the two Ethernet switches.

– Connections shown in orange belong to fault domain 1.

– Connections shown in blue belong to fault domain 2.

2. Connect fault domain 1 (in orange) to switch 1.

– Top storage controller: port 1 to switch 1

– Top storage controller: port 3 to switch 1

– Bottom storage controller: port 1 to switch 1

– Bottom storage controller: port 3 to switch 1

3. Connect fault domain 2 (in blue) to switch 2.

– Top storage controller: port 2 to switch 2

– Top storage controller: port 4 to switch 2

– Bottom storage controller: port 2 to switch 2

– Bottom storage controller: port 4 to switch 2

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.

Connect to Management Network
