摘要: A storage device has a capability of learning access patterns by which a plurality of computers access to the device. The storage device stores a specific access history for each computer and causes a management computer to report a type of file access. This allows the storage device to save information in a cache memory before start of a file access to be executed by the computer.

摘要: A fault of an operating system (hereafter referred to as “OS”) is observed without adding dedicated hardware. Besides AP fault monitoring, check-point information is preserved at high speed without adding dedicated hardware. In a computer having a multi-OS environment, an AP fault monitor and a monitored AP operate on a first OS. A fault monitor operates on a second OS. Each of the first OS and the AP fault monitor transmits an alive message to the fault monitor by utilizing an inter-OS communication function of a multi-OS controller. The fault monitor monitors the alive message of each of the first OS and the AP fault monitor. The monitored AP transmits an alive message to the AP fault monitor. The AP fault monitor monitors it. The monitored AP preserves check-point information in a region of a memory. In the region of the memory, information is preserved by a fault and restart of the first OS as well.
