Abstract
The present invention is directed to a system and method 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.
Claims26
A method of performing a full duplex open in a fibre channel network having an initiator and a bridge, comprising:
- initiating an open by the initiator with the bridge, the bridge having a primary physical address and an alias physical address, the alias physical address representing a target device communicatively coupled to the bridge, wherein the open is initiated utilizing the primary physical address;
- and
- communicating with the initiator by the target device.
A system, comprising:
- a host suitable for communicating utilizing fibre channel;
- and
- a bridge having a primary arbitrated loop physical address corresponding to a first device and at least one alias arbitrated loop physical address which corresponds to a second device, the bridge communicatively coupled to the host through an arbitrated loop fibre channel network
- wherein a full duplex open is initiated by the host with the bridge utilizing the primary arbitrated loop physical address.
A method of performing a full duplex open in a fibre channel arbitrated loop having an initiator and a bridge, comprising:
- initiating an open by the initiator with the bridge, the bridge having a primary arbitrated loop physical address and at least two alias arbitrated loop physical addresses, the alias arbitrated loop physical addresses representing at least two target devices communicatively coupled to the bridge, wherein the open is initiated utilizing the primary arbitrated loop physical address;
- and
- communicating with the initiator by the at least two target devices.
