Improving the multi-site software update for extension switches by automatically assigning extension switches at each data center with a role and then providing state messages between the extension switches to stage software update operations between the various extension switches that are involved. This allows the network administrator to commence the software update process on the extension switches at each data center without waiting for any extension switch to complete operations. The extension switches communicate with each other and the software update process completes automatically, with all extension switches at all data centers updated without further network administrator input.

Systems for performing inline wire speed data deduplication are described herein. Some embodiments include a device for inline data deduplication that includes one or more input ports for receiving an input data stream containing duplicates, one or more output ports for providing a data deduplicated output data stream, and an inline data deduplication engine coupled to said one or more input ports and said one or more output ports to process input data containing duplicates into output data which is data deduplicated, said inline data deduplication engine having an inline data deduplication bandwidth of at least 4 Gigabytes per second.

Inline wire speed deduplication system

If there are mirrored WAN optimization devices, a master WAN optimization device sends a datagram received from a source across the WAN and sends a copy of the datagram to a mirroring WAN optimization device. When the mirroring WAN optimization device ACKs the mirrored datagram, the master WAN optimization device ACKs the host. When the master WAN optimization device receives the ACK from the WAN, the ACK is forwarded to the mirroring WAN optimization device, which deletes the mirrored datagram. Alternatively, the mirroring WAN optimization device can receive the datagram from the source, store it and forward it to the master WAN optimization device, which sends the datagram across the WAN and sends an ACK to the host. When the ACK from the WAN is received, the master WAN optimization device forwards the ACK to the mirroring WAN optimization device, when then deletes the mirrored datagram.

Embodiments according to the invention relate to frame redirection, which includes methods to intercept and re-route traffic between an initiator and a target. When a frame is redirected, an initiator issues a frame to the target, but the frame is received by a virtual target in a redirection switch by allowing the redirection switch to use the WWN of the actual target. From the perspective of the initiator, the target resides on the redirection switch. From the redirection switch, the frame is sent to the actual target by allowing the redirection switch to use the identity of the initiator. In other words, the redirection switch presents the WWN of the initiator to the target when the redirected frame is sent to the target. From the perspective of the target, the frame is received as if it originated at the initiator.
