Abstract: A storage system according to the present invention comprises a controller and multiple storage devices, constitutes a RAID group from (n+m) number of storage devices, wherein the storage system stores write data from a host computer to n number of storage devices, and stores redundant data generated from the n number of data to m number of storage devices. When failure occurs to at least one storage device, the controller reads data in a compressed state and redundant data from each of the storage devices where failure has not occurred in the storage devices constituting the RAID group, and transmits the read data in the compressed state to the storage device which is a data recovery destination.

Abstract: A system calculates, for each point in time, an actual license fee at the point in time on the basis of management information, calculates a predicted license fee at the time of the end of a budget management period on the basis of a time series of the actual license fee, calculates a software use situation in which the predicted license fee is within a budget in a case in which the predicted license fee exceeds the budget, and performs control including stopping a certain piece of software of a certain server. The management information includes information indicating, for each piece of software, a license type, a license purchase unit by type, a fixed license fee regardless of a license period, a license fee per period unit of the license period, and a period unit of the license period.

Abstract: A storage device according to an aspect of the present invention comprises a plurality of memory devices and a storage controller. The memory devices provide the storage controller with a storage space which comprises a plurality of sectors, each said sector including a write data memory region and an inspection code memory region. When the memory devices receive a read request from the storage controller, if the sector which is the subject of the read request has not been written to, an inspection code is generated on the basis of information included in the read request, and data of a prescribed pattern is transmitted with the inspection code to the storage controller.
