Abstract
Methods and apparatus for managing exchanges in a network device of a storage area network are disclosed. In a first 'host-side' exchange initiated by an initiator and between the initiator and the network device, one or more frames are received from an initiator and/or sent to the initiator. At least one of the frames pertains to access of a virtual storage location of a virtual storage unit representing one or more physical storage locations on one or more physical storage units of the storage area network. One or more 'disk-side' exchanges between the network device and one or more targets (i.e., physical storage units) are initiated in response to the first exchange. In the disk-side exchanges, one or more frames are sent from the network device to one of the targets and/or received from the target. Exchange information for the host-side exchange and the associated disk-side exchanges are updated throughout the exchanges.
