Split-Function Ports for iSCSI – Dell R720
For increased redundancy/high-availability, when using
two Mellanox ConnectX-3 dual-port adapters for both
connectivity between HA IONs and fabric connectivity to
the initiator nodes (as when running iSCSI), it is best to
split the functionality between the cards. This allows
each card to be used for both a redundant connection
to the partner node and to the fabric. That way, if one
adapter fails, and both its ports are lost, the system can
continue to run. The mode will be partially degraded,
but not system-failed, with the remaining cluster
interconnect and iSCSI ports on the other adapter.
It is important to use the correct ports for fabric and ION interconnectivity in this case. The diagram
above, along with the rear-view picture of the ION chassis shown previously, describe the ports to be
used to connect IONs, and the ports to be used when connecting to the fabric.
iSCSI Port Assignments
• PCIe Slot 1: left port = iSCSI, right port = cluster interconnect (Eth)
• PCIe Slot 2: both ports = iSCSI
• PCIe Slot 3: left port = iSCSI, right port = cluster interconnect (Eth)
