1 NET MGT port connects to the cluster interconnect port on the partner Controller (Ethernet). 4 NET 2 port connects to the NET 2 port on the partner Controller(Ethernet). 2 Cluster interconnect network port connects to the NET MGT port on the partner Controller (Ethernet). The cluster interconnect network port is labeled as <- - ->. 5 SAS HBA ports connect between the Controllers and connect the Controllers to the Drive Enclosures (SAS). 3 NET 3 port connects to the NET 1 port on the Pilot node (Ethernet).
