InfiniBand Private Network Physical Connections (Sun ZFS Storage 7320 Appliance)

The Sun ZFS Storage 7320 appliance connects to the InfiniBand private network through one of the two Sun ZFS Storage 7320 storage controllers. The Sun ZFS Storage 7320 storage controller contains one Sun Dual Port 40GB InfiniBand QDR HCA. The two ports in each InfiniBand HCA are bonded together to increase available bandwidth. When bonded, the two ports appear as a single port, with a single IP address assigned to the two bonded ports, resulting in one IP address for InfiniBand private network connections for the Sun ZFS Storage 7320 storage controller.

The two ports in the InfiniBand HCA connect to a different leaf switch to provide redundancy between the Sun ZFS Storage 7320 storage controller and the leaf switches. The following figure shows how redundancy is achieved with the InfiniBand connections between the Sun ZFS Storage 7320 storage controller and the leaf switches in a half rack configuration.
