The Flex System FC5022 16Gb SAN Scalable Switches can be installed in bays 1, 2, 3, and 4 of the Flex
System chassis. A supported adapter card must be installed in a corresponding slot of the compute node
(slot A1 when switches are installed in bays 1 and 2 or slot A2 when switches are in bays 3 and 4).
With compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC) these
switches can only be installed in bays 3 and 4 because integrated NICs ports are routed to bays 1 and 2
with a specialized periscope connector and the FC adapter card cannot be installed in slot A1. When
needed, however, the periscope connector can be replaced with an FC adapter card, in which case the
integrated NIC will be disabled and FC switches can be used in bays 1 and 2.
Table 7 shows the connections between dual-port and 4-port FC adapters installed in the compute nodes
other than x222 to the switch bays in the chassis with Flex System FC5022 16 Gb SAN Scalable Switches.

Table 8 shows the connections between 4-port adapters installed in the x222 compute nodes to the switch
bays in the chassis with Flex System FC5022 16Gb SAN Scalable Switches.

With the x222, each node bay consumes four ports on the switch, therefore, additional port licenses might
be needed depending on your configuration (see Table 1 for FoD port upgrades).
