ABSTRACT:
A processing apparatus which stores a first information piece about attributes identifying a specific process generating data input/output requests in such a manner that the first information piece is associated with a second information piece identifying at least one of the physical paths as at least one first physical path, and which, when transmitting first data input/output requests generated by the process identified by the first information piece to the storage apparatus, transmits the first data input/output requests to the storage apparatus via the first physical path identified by the second information piece associated with the first information piece and, when transmitting second data input/output requests generated by a process not identified by the first information piece to the storage apparatus, transmits the second data input/output requests to the storage apparatus via at least one second physical path different from the first physical path of the plurality of physical paths.
