摘要： A file server has plural NAS nodes having three processors dispersed in function, a shared cache memory shared between the plural NAS nodes and backed up by a battery, and plural storage devices. A log area for storing data with respect to an access request received by each NAS node is arranged in the shared cache memory. A network processor stores the data with respect to the access request to the log area, and transfers the data of the memory by a DMA at a reading time. Even when a failure is happened in a certain NAS node, another NAS node restores a file system using the log and continues processing to store the data with respect to the access request to the shared cache memory.

摘要： The present invention enables to secure data reliability by avoiding data loss in an early failure period of an operation of a disk array system to which no particular measures have been taken conventionally. A controller of the disk array system stores first data to be stored in a HDD into a part of the region of one or more HDDs of an overall storage region composed of a plurality of HDDs and stores backup data of the stored first data into a part of the region of one or more HDDs in such a manner that they may be stored in the different HDDs. When there are no enough free space regions to store the first data in the overall storage region, the region in which the backup data is stored is overwritten to be used.

摘要： When a plurality of applications operating in a host computer or a storage system uses a same pool, actual data constantly allocated to an upper tier drive satisfying the required response performance will continue to increase. Therefore, when data is migrated by IOPS in page units, the access performance such as the response speed may not be satisfied. Therefore, according to the present invention, multiple virtual volumes used in applications are subjected to grouping. Relocation conditions corresponding to performances required for each group are set in advance, and reallocation of tiers according to the relocation conditions is performed.

摘要： If an I/O load on a first virtual storage area falls below a first threshold, a controller copies data in a first storage area, which is allocated to the first virtual storage area, to a third storage area in a second tier storage area, and allocates the third storage area instead of the first storage area to the first virtual storage area. If an I/O load on a second virtual storage area exceeds a second threshold which is greater than said first threshold, the controller copies data in a second storage area, which is allocated to the second virtual storage area, to a fourth storage area in a first tier storage area, and allocates the fourth storage area instead of the second storage area to the second virtual storage area.
