摘要： The present invention provides a storage system capable of having a large-scale configuration for maintaining a write access response speed and reliability upon an occurrence of a failed cache and its control method. Plural clusters that control a disk drive connected thereto and have a cache memory are connected to one another through a cross coupling network, and write data in the cache memory of the clusters is mutually made redundant in the cache memories in two clusters that jointly use the same disk drive. When a failure occurs in the cache memory, the cluster that uses the disk drive jointly with the cluster having the cache memory in which the failure occurs performs processing for getting access to the disk drive operated by the cluster having the cache memory in which the failure occurs, and the other normally-operated cluster is operated to only make redundant the write data in the cache memory in its cluster.

摘要： A computing system 1000 includes a plurality of computing units 100; a tiered (i.e. hierarchical) storage unit, including a first storage medium 140 and a second storage medium 160 having a data transfer rate lower than the first storage medium, connected to a plurality of the computing units; and a system management unit 180 connected to a plurality of the computing units and the tiered storage unit. System management unit 180 creates or obtains a computation job execution schedule for a plurality of the computing units, plans a data migration in the tiered storage unit according to the execution schedule, and instructs the tiered storage unit to migrate a data based on the plan. System management unit 180 may be configured to store a file to be read by a computing unit in the first medium before the file is read or make free space by migrating data in the first storage medium to the second storage medium.

摘要： Disk array system is presented wherein the plurality of disk array controlling units operate as the sole disk array controller so as to restrain the performance of the cache memory sections of the respective disk array controlling units from deteriorating owing to their physical packaging locations and to maximize the performance thereof in proportion to the number of the controlling units in use. Disk array controller is provided, which controller comprises a host switch interface section, the plurality of respective disk array controlling units provided with a channel interface section, a disc interface section and a cache memory section and a mutual connection network in connection with the channel interface sections, the disc interface sections and the cache memory sections of said respective disk array controlling units. Access performance to the cache memory sections that are dispersedly disposed between the respective disk array controlling units improves so as to enhance the performance of the disk array controller in proportion to the number of the disk array controlling units in use.
