ABSTRACT:
Transmission/reception of each request is carried out through one and the same port. When requests are concentrated on one port, the port has to process all the requests. The processing load on the port increases correspondingly. A table in which request processing and its control information are recorded and a table in which ports that can be requested are recorded are prepared in a shared area inside a disk subsystem. Processing is requested with reference to those tables. The load on the port on which requests are concentrated is distributed, and the throughput to request sources is improved.
