Next steps

Install or enable MPIO on the host servers.

NOTE: After the Storage Center configuration is complete, run the host access wizard to configure host server access

and apply MPIO best practices.

For the latest best practices, see the Dell Storage Center Best Practices document on

the Dell TechCenter site (http://en.community.dell.com/techcenter/storage/).

One iSCSI Network with Dual 1 GbE 4-Port Storage Controllers

Use one iSCSI network to prevent an unavailable port or storage controller from causing a loss of connectivity between the host

servers and a

storage system with dual 1 GbE 4-port storage controllers.

About this task

This configuration includes two fault domains, one iSCSI network, and one Ethernet switch. Each storage controller connects to the

Ethernet switch using four iSCSI connections.

• If a physical port becomes unavailable, the virtual port moves to another physical port in the same fault domain on the same

storage controller.

• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to the physical ports on the

other storage controller.

NOTE: This configuration is vulnerable to switch unavailability, which results in a loss of connectivity between the host

servers and the storage system.

Steps

1. Connect each server to the iSCSI network.

2. Connect fault domain 1 (shown in orange) to the iSCSI network.

• Storage controller 1: port 1 to the Ethernet switch

• Storage controller 1: port 3 to the Ethernet switch

• Storage controller 2: port 1 to the Ethernet switch

• Storage controller 2: port 3 to the Ethernet switch

3. Connect fault domain 2 (shown in blue) to the iSCSI network.

• Storage controller 1: port 2 to the Ethernet switch

• Storage controller 1: port 4 to the Ethernet switch

• Storage controller 2: port 2 to the Ethernet switch

• Storage controller 2: port 4 to the Ethernet switch
