<P>PROBLEM TO BE SOLVED: To provide a fault tolerant system capable of suppressing cost and having flexibility. <P>SOLUTION: A second physical server is connected to a first physical server. The first physical server has a first hypervisor for executing a first virtual server on the first physical server, and the second physical server has a second hypervisor for executing a second virtual server on the second physical server. The first and second hypervisors communicate with each other so as to control synchronization between the first and second virtual servers. Preferably, a switch device is connected to the first and second physical servers and a storage device. The switch device controls synchronization of data I/O to the storage device of the first and second virtual servers. <P>COPYRIGHT: (C)2012,JPO&INPIT |
