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 10 GbE 2-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 10 GbE 2-port storage controller.
About this task
This configuration includes two fault domains, two iSCSI networks, and two Ethernet switches. The storage controller connects to
the Ethernet switches using two iSCSI connections.
If a physical port or 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 the iSCSI network.
2. Connect fault domain 1 (shown in orange) to iSCSI network 1.
Storage controller: port 1 to Ethernet switch 1.
3. Connect fault domain 2 (shown in orange) to iSCSI network 2.
Storage controller: port 2 to Ethernet switch 2.
