Virtual Port Mode — One iSCSI Network with Dual 10 GbE 2-Port Storage Controllers
Use one iSCSI network with virtual port mode 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.
