Patent number: 8051203Abstract: Techniques are disclosed for abstracting write acceleration techniques and tape acceleration techniques away from transport providers (e.g., away from an FC or FCIP interlink between two storage area networks) and allowing acceleration to be provided as a service by nodes within the storage area network (SAN). Doing so allows the acceleration service to be provided anywhere in the SAN. Further, doing so allows users to scale the acceleration service as needed, without having to create awkward topologies of multiple VSANS. Further still, as the acceleration service is offered independently from the transport, compression, encryption, and other services may be offered as part of the transport between the FC/FCIP connection along with the acceleration service.Type: GrantFiled: May 29, 2009Date of Patent: November 1, 2011Assignee: Cisco Technology, Inc.Inventors: Murali Basavaiah, Kiron Haltore, Anand Parthasarathy

Patent number: 7949792Abstract: The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol (“TCP”) termination over a Fibre Channel (“FC”) fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage (“NAS”) protocol data units (“PDUs”) are parsed and delivered.Type: GrantFiled: April 29, 2004Date of Patent: May 24, 2011Assignee: Cisco Technology, Inc.Inventors: Timothy Kujk, David Thompson, Stephen DeGroote, Murali Basavaiah, Anand Parthasarathy
