Fabric A switches
A single switch is implemented for all I/O, and allows maximum signal consolidation without forcing
bifurcation of the Ethernet fabric. Switches accept up to 16 lanes from Fabric A and output up to
eight lanes at the external ports. A switch is the only Fabric A card that can support the full four-lane
count from Fabric A. When equipped with four M520 servers and quad-port LOMs, VRTX can take
full advantage of all 16 internal ports (four per server node).
