Abstract
A plurality of SMP modules and an IOP module communicate storage traffic via respective corresponding I/O controllers coupled to respective physical ports of a switch fabric by addressing cells to physical port addresses corresponding to the physical ports. One of the SMPs executes initiator software to partially manage the storage traffic and the IOP executes target software to partially manage the storage traffic. Storage controllers are coupled to the IOP, enabling communication with storage devices, such as disk drives, tape drives, and/or networks of same. Respective network identification registers are included in each of the I/O controller corresponding to the SMP executing the initiator software and the I/O controller corresponding to the IOP. Transport of the storage traffic in accordance with a particular VLAN is enabled by writing a same particular value into each of the network identification registers.
