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 Fibre Channel Fabrics with a Single 16 Gb 2-Port Storage Controller
Use two Fibre Channel (FC) fabrics to prevent an unavailable port or switch from causing a loss of connectivity between the host
servers and a
storage system with a single 16 Gb 2-port storage controller.
About this task
This configuration includes two fault domains, two FC fabrics, and two FC switches. The storage controller connects to each FC
switch using one FC connection.
If a physical port or FC 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 FC fabric.
2. Connect fault domain 1 (shown in orange) to fabric 1.
Storage controller: port 1 to FC switch 1.
3. Connect fault domain 2 (shown in blue) to fabric 2.
Storage controller: port 2 to FC switch 2.
