Abstract: A local-memory side data transfer unit increments the number of addresses, reads out data from a local memory, and stores the data into a cache memory of a remote-memory side data transfer unit. For preventing data mismatching with the local memory from being stored into the cache memory, a cache clearing operation is executed in units of an elapse of a round trip time period for data transfer between the local memory and the remote memory. Alternatively, the cache clearing operation is executed upon receipt of a signal notifying data transfer of data stored at a specified address.

Abstract: An information processing device that are capable of continuing access to an I/O device by operational computers even when a failure has occurred in a management computer is provided.A virtualization bridge (300) includes a monitoring unit (307) and a backup control unit (308). The virtualization bridge (300) provides operational computers (200) with virtual functions of an I/O device (400). The monitoring unit (307) detects failures in a management computer (100). The backup control unit (308) generates backup management information (341) on the basis of packets transmitted and received between the management computer (100) and the I/O device (400), and, when a failure in the management computer (100) is detected by the monitoring unit (307), controls the I/O device 400 on the basis of the backup management information (341) in place of the management computer (100).

Abstract: [Problem] To enable a user to control a virtualization system without wasting resources. [Solution] A virtualization system containing an operation unit, an operation reporting unit, a message processing unit, and an operation processing unit. The operation unit outputs a signal on the basis of a user operation. The operation reporting unit transmits to a network an operation message generated by appending, to first operation information indicating the content of the operation corresponding to that signal, a header addressed to a server providing virtual machines. The message processing unit generates second operation information indicating that the operation indicated with the first operation information has been performed with respect to the virtual machine corresponding to the transmission source of that operation message. On the basis of the second operation information, the operation processing unit instructs the virtual machine corresponding to the transmission source to perform the action corresponding to that operation.
