<P>PROBLEM TO BE SOLVED: To prevent re-copying caused by a memory change from an I/O device generated in a migration without depending on a virtual computer environment. <P>SOLUTION: A computer system in which a first computer 10a and a second computer 20a are connected to a plurality of I/O devices 30a and 30b via a first switch 20a and a second switch 20b, in which a memory copy control unit 201a of the first switch 20a notifies the second switch 20b of memory copy information to be executed as copying region information and replication region information. When receiving data from the I/O device 30b, a replication control unit 202b of the second switch autonomously transmits, replicates and suspends a transaction based on the notified copying region information and replication region information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
