Patent ID: 8051203

Claim:
A first routing device in a first storage area network (SAN), comprising: a processor; and a memory, wherein the memory includes a program configured to perform an operation for providing an acceleration service for a write operation initiated between an initiating device attached to the first SAN and a target device attached to a second SAN, and wherein the first SAN and the second SAN are connected via a network link, the operation comprising: receiving a write operation sent from the initiating device attached to the first SAN, wherein the write operation has been redirected to a first routing device based on an entry in a redirect table shared among a plurality of routing devices in the first SAN, wherein the redirect table provides a network address translation (NAT) access control list (ACL), wherein the NAT ACL specifies a plurality of source/destination address pairs to redirect frames routed by the routing devices of the first SAN to a respective redirected source/destination address pair, and performing the acceleration service to transfer data between the initiating device and the target device in order to complete the write operation, wherein the acceleration service is performed in conjunction with a second routing device on the second SAN.
