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/).
One iSCSI Network with Dual 10 GbE 2-Port Storage Controllers
Use one iSCSI network to prevent an unavailable port or storage controller from causing a loss of connectivity between the host
servers and a storage system with dual 10 GbE 2-Port storage controllers.
About this task
This configuration includes one fault domain, one iSCSI network, and one Ethernet switch. Each storage controller connects to the
Ethernet switch using two iSCSI connections.
• If a physical port becomes unavailable, the virtual port moves to another port in the fault domain.
• 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 1: port 2 to the Ethernet switch
• Storage controller 2: port 1 to the Ethernet switch
• Storage controller 2: port 2 to the Ethernet switch
