QLE2564-Dell Dell 8GB Quad Port PCI-Express Fibre Channel Host Bus Adapter

The PCI-Express 2.0 X8 interface is a type of connection that is used to connect expansion cards to a server. The X8 indicates the number of lanes that are available for data transfer. In this case, this supports eight lanes, which allows for high-speed data transfer between the server and the SAN.

This supports four ports, which means that it can connect to four different SANs simultaneously. This feature allows for increased flexibility and can be particularly useful in larger data centers where multiple SANs are used.
