A system and method are described for increasing performance of operations implemented in a storage system utilizing fibre channel, such as by enabling full duplex opens when a JBOD/bridge is involved. In an aspect of the present invention, a method of performing a full duplex open in a fibre channel network having an initiator and a bridge may include initiating an open by the initiator with the bridge. The bridge has a primary physical address and an alias physical address. The alias physical address represents a target device communicatively coupled to the bridge, wherein the open is initiated utilizing the primary physical address. The initiator communicates with the target device.

Communications method within an arbitrated loop fibre channel network

The method and apparatus provides a data processing system. The data processing system includes a primary bus, a secondary bus, and a host processor connected to the primary bus. The data processing system includes a first secondary processor connected to the primacy bus and the secondary bus. Additionally, a second secondary processor is connected to the secondary bus. The first secondary processor and the second secondary processor forms cascaded processors for input/output functions. Selected functions normally performed by the second secondary processor are performed by the first secondary processor, wherein a division of workload increases performance of the data processing system. This architecture allows shifting of workload down to the secondary bus.
