Ports 1 through 42 provide up to 42 internal ports (available through Ports-On-Demand
activation) connected to 14 compute nodes at the midplane, auto-negotiating to 10-Gbps
Ethernet.
Ports 43 through 56 provide up to 14 external ports (available through Ports-On-Demand
activation), capable of supporting 1-Gbps Ethernet or 10-Gbps Ethernet through 10-Gbps SFP+
transceivers.
Ports 57 and 58 provide two Quad SFP (QSFP) ports (available through Ports-On-Demand
activation) that can support 40-Gbps Ethernet, or 4x10-Gbps Ethernet in breakout mode.
