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.
