Abstract: A system and method are provided for processing storage commands between a host and a target. The system includes a first line card, a system card, and a second line card. The storage command that is issued from the host is received by the first line card. The first line card determines whether or not it can process the request by itself and, if so, forwards the storage command to the second line card for forwarding (and eventual processing) by the target. If the first line card cannot process the storage command by itself, it forwards the storage command to the system card for additional processing. The revised storage command is issued from the system card to the first line card. The first line card then issues the revised storage command to the second line card for eventual processing by the target.

Abstract: A method of linking at least two network switches is disclosed, wherein each network switch switches data traffic of a plurality of devices, through a plurality of couplings. The method comprises the steps of generating a data stream including an identifier to be sent from a first to a second network switch, generating a number identifying one of the couplings from the identifier, and using the identified coupling for transfer of the data stream.

Abstract: Network processors controlled by software are used to implement the FC-1 and FC-2 layer functions. Each Network Processor comprises a fabric processor, an executive processor, channel processors and associated serial data processors. Special ASICs are not required since all of the Fiber Channel layers may be implementation with the network processors under software control.

Abstract: A system, apparatus and method for an efficiently performing address lookups and switching for computer networks is disclosed. The present disclosure provides for address translation between network devices utilizing different protocols. The system, apparatus and method described herein provide for address translation for encapsulated communications to enable mixed protocol communications using a network switch fabric system.
