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 located on the Dell TechCenter (http://en.community.dell.com/

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 4–port storage
controller.
About this task
In this configuration, there are 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 storage system.
Steps
1. Connect each server to the FC fabric.
2. Connect fault domain 1 (shown in orange) to the fabric 1.
