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
In this configuration, there are two fault domains, 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 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
