An interserver communication mechanism which can eliminate the need for preparing an external I/O device for each of physical servers for communication between the physical servers and can avoid generation of overhead caused by protocol conversion. A plurality of physical servers are connected to the interserver communication mechanism via I/O link and I/O switch. The interserver communication mechanism has a read instruction generator for issuing an instruction to access data of the physical servers and a write instruction generator for transmitting the read data to the other server. Data transfer between the physical servers is carried out in the interior of the interserver communication mechanism by reading out data from a data transmission originator, writing the read data to a transmission destination as it is, and directly turning back the data at the interserver communication mechanism.
