3. Connect fault domain 2 (shown in orange) to iSCSI network 2.
Storage controller: port 2 to Ethernet switch 2.

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/

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 a 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
