3. Connect fault domain 2 (shown in blue) to fabric 2.
Storage controller: port 2 to FC 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

Two Fibre Channel Fabrics with a Single 8 Gb 4-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 8 Gb 4-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 two FC 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 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 both FC fabrics.
2. Connect fault domain 1 (shown in orange) to fabric 1.
• Storage controller 1: port 1 → FC switch 1
