An engineer must connect a Cisco UCS Fabric Interconnect to a storage array using a Fibre Channel protocol. The SAN must be directly connected to the UCS fabric interconnects using ports 1/1 and 1/2.

When directly connecting a Cisco UCS Fabric Interconnect to a Fibre Channel storage array, the Fabric Interconnect should be configured in Fibre Channel end-host mode, making it appear as an end-host to the upstream SAN. The ports connecting directly to the storage array are then configured as Fibre Channel uplink ports, which handle the physical Fibre Channel connectivity to the storage system, simplifying SAN integration.

While "Fibre Channel storage port" exists, for direct native Fibre Channel connection in end-host mode, "Fibre Channel uplink port" is the standard.

"Fibre Channel switching mode" makes the Fabric Interconnect act as a full Fibre Channel switch, requiring zoning and more complex SAN administration, which is typically avoided for direct attachment.

"Fibre Channel switching mode" is incorrect for direct attachment that aims for simplicity, and "Fibre Channel storage port" is not the primary choice for direct native FC connectivity in switching mode.
