Patent ID: 8171164

Claim:
A computer-implemented method for target routing by initiator, using Internet small computer system interface, the computer-implemented method comprising: obtaining a logical unit number configuration containing a plurality of logical unit numbers; generating an Internet small computer system interface software target for a plurality of requesting devices to form a single target; routing a plurality of input/output requests received at the Internet small computer system interface from the plurality of requesting devices to the single target; responsive to receiving an input/output request having an Internet protocol address associated with a requesting device in the plurality of requesting devices, mapping the Internet protocol address associated with the requesting device to a logical unit number in the plurality of logical unit numbers to form a mapping; and setting, at the single target, a path for the input/output request from the requesting device to a backing file based on the mapping between the Internet protocol address associated with the requesting device and the logical unit number, wherein the Internet protocol address associated with the requesting device is included in the path to the backing file.
