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/).

Two iSCSI Networks with a Single 1 GbE 4-Port Storage Controller

Use two iSCSI networks to prevent an unavailable port or switch from causing a loss of connectivity between the host servers and

storage system with a single 1 GbE 4-port storage controller.

About this task

In this configuration, there are two fault domains, two iSCSI networks, and two Ethernet switches. The storage controller connects

to each Ethernet switch using two iSCSI connections.

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

controller.

• If an Ethernet switch becomes unavailable, the storage system is accessed from the switch in the other fault domain.

NOTE: This configuration is vulnerable to storage controller unavailability, which results in a loss of connectivity between

the host servers and the storage system.

Steps

1. Connect each server to both iSCSI networks.

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

• Storage controller 1: port 1 to Ethernet switch 1

• Storage controller 1: port 3 to Ethernet switch 1

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

• Storage controller 1: port 2 to Ethernet switch 2

• Storage controller 1: port 4 to Ethernet switch 2
