Fibre Channel devices can connect to a fabric using a Direct Fabric Attach. Direct Fabric Attach devices do
not have an AL_PA and the least significant byte of their N_Port ID is usually 0. This is dependent on the
switch implementation. Not all switches adhere to this scheme.
Some switches enable devices in Private Loop mode to connect to a fabric. These switches typically translate
the Private Loop device as a Direct Fabric Attach device to the rest of the fabric. These switches also typically
translate the rest of the fabric as Private Loop devices to the Private Loop device.
