Dell Storage Center SCv2000 Deployment Manual page 52

• If a physical port becomes unavailable, the storage system is accessed from another port on the
Ethernet switch.
• 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 iSCSI network.
2. Connect fault domain 1 (shown in orange) to the iSCSI network.
• Storage controller 1: port 1 to the Ethernet switch
• Storage controller 2: port 1 to the Ethernet switch
3. Connect fault domain 2 (shown in blue) to the iSCSI network.
• Storage controller 1: port 2 to the Ethernet switch
• Storage controller 2: port 2 to the Ethernet switch

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
