Fibre Channel (FC) initiator is the endpoint that initiates a session and that sends commands. Fibre Channel (FC) target is the endpoint that does not initiate sessions, but instead waits for initiators' commands and provides required input/output data transfers. The target usually provides to the initiators one or more LUNs, because otherwise no read or write command would be possible.
Most FC HBA cards are found in servers and are usually configured as a Fibre Channel (FC) initiator then connected to some type of storage via a controller (not a FC HBA) card in the storage device. But in certain uncommon situations FC HBA cards in servers can be configured as a Fibre Channel (FC) target as well.
FC HBA cards are sometimes also used in storage devices (ie. disk/nas arrays or tape libraries) instead of storage controllers cards and can be configured as either FC Initiator or Target.
