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

Two Fibre Channel Fabrics with Dual 8 Gb 4-Port Storage Controllers
Use two Fibre Channel (FC) fabrics to prevent an unavailable port, switch, or storage controller from
causing a loss of connectivity between host servers and a
storage system with dual 8 Gb 4-port storage
controllers.
About this task
In this configuration, there are two fault domains, two FC fabrics, and two FC switches. The storage
controllers connect to each FC switch using two FC 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 an FC switch becomes unavailable, the storage system is accessed from the switch in the other fault
domain.
• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to
the physical ports on the other storage controller.
