You can find a complete list on the QLogic website. QLogic Adapter model numbers follow a numbering scheme, making the type of adapter easy to determine. All QLogic adapter model numbers start off with a Q. Q, for QLogic. The next two characters will indicate the host interconnect. LE for PCI Express. The first number in the model is I/O technology used by the card. Fibre Channel Adapters start with a two, where iSCSI Adapter would start with a four. The second number represents the sub-technology: A five would indicate an 8Gb FCA. The third number represents the design generation and the final number indicates the port count. Sometimes there is a final character that is used for other identification purposes. A C for instance, would indicate a copper Adapter, where a dash BK would indicate that the adapter was solid in bulk. Using this information, we can properly identify a QLE 2562 as QLogic Fibre Channel Host Bus Adapter with a PCI Express host interconnect with two FC ports. FC 202 July 2009 FC 202.01
