Summary:PROBLEM TO BE SOLVED: To provide a means for efficiently performing I/O processing while minimizing the use of processor, main storage and system bus resource of a server computer by directly transferring data between a network card and an I/O device such as network adapter or disk controller. SOLUTION: In this network file server system, in the case of processing a remote file system request through a remote file processing means 136 by a network card 130 while using a file on a disk through a local file system 160 for an application or operating system(OS) to be operated on a server computer 100, data are directly transferred between a disk controller 140 and the network card 130. Thus, the number of times of data transfer using a main memory 120 between the disk controller 140 and network card 130 is decreased so that high-speed processing is enabled.
