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/

One Fibre Channel Fabric with Dual 8 Gb 4–Port Storage Controllers
Use one Fibre Channel (FC) fabric to prevent an unavailable port or storage controller from causing a loss
of connectivity between the host servers a storage system with dual 8 Gb 4–portstorage controllers.
About this task
In this configuration, there are two fault domains, one fabric, and one FC switch. Each storage controller
connects to the FC switch using four 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 a storage controller becomes unavailable, the virtual ports on the offline storage controller move to
the physical ports on the other storage controller.
NOTE: This configuration is vulnerable to switch 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.
• Storage controller 1: port 1 to the FC switch
• Storage controller 1: port 3 to the FC switch
• Storage controller 2: port 1 to the FC switch
• Storage controller 2: port 3 to the FC switch
3. Connect fault domain 2 (shown in blue) to the fabric.
• Storage controller 1: port 2 to the FC switch
• Storage controller 1: port 4 to the FC switch
• Storage controller 2: port 2 to the FC switch
• Storage controller 2: port 4 to the FC switch
