摘要： Log manipulation by a first administrator is prevented so that the reliability of system auditing can be improved.After receiving a service start request from a management computer, a storage subsystem creates a first resource group regarding which access by a host computer is permitted, and also creates a second resource group regarding which access by the management computer is permitted. The storage subsystem further creates a data storage area, to which data is to be written by the host computer, and makes the data storage area belong to the first resource group, while it also creates a log storage area, in which log information indicating past operation performed on the data storage area by the host computer is to be recorded, and makes the log storage area belong to the second resource group.

摘要： A file, for which writing has been reserved, in a file-sharing system can be efficiently read. A check-in file agent is provided in a computer that executes check-in of a file as the file-write reserving processing, a file manager is provided in a file-sharing computer, and a check-out file agent is provided in a computer that executes check-out of a file as the file reading processing. Upon request for check-in of a file, the check-in file agent divides the file into divided files and generates metadata that indicates the order of division of the file, and transmits them to the file-sharing computer for storage therein. Upon request for check-out of the file, the check-out file agent receives the metadata from the file-sharing computer, and based on the metadata, sequentially receives the divided files to generate a file to be checked out.

摘要： Since the threshold excess is judged by a value of high-workload IO of backup that is designed on the assumption that the workload of storage is high, whether the performance limit has been reached remains uncertain. Furthermore, although an optimistic prediction trend with low workload trend and a pessimistic prediction trend with high pessimistic workload trend are presented, LUs that require improvement remain uncertain. Moreover, the time to improve the configuration and the effect of the improvement remain uncertain. To improve the configuration, configuration information, performance information, and operation information are acquired from storage, a performance limit excess time is predicted based on the performance information excluding LUs exceeding the performance trend, and an optimal improved configuration is determined from the performance limit after improvement and the time required for the improvement.

摘要翻译： 由于阈值超出值是以假设存储量大的假设设计的高工作负载IO的值来判断的，所以性能限制是否达到仍然是不确定的。 此外，虽然呈现出低工作量趋势的乐观预测趋势，以及悲观的工作量倾向悲观的预测趋势，但需要改进的LU仍然不确定。 此外，改进配置的时间和改进的效果仍然不确定。 为了改善配置，从存储获取配置信息，性能信息和操作信息，基于除了超过性能趋势的LU的性能信息，预测性能限制超时，并且根据性能限制确定最佳改进配置 改善和改善所需的时间。

摘要： The present invention provides a criterion for determining whether or not to apply de-duplication processing. That is, by setting a reduction effect threshold to control switching the de-duplication between ON and OFF, the present invention allows operation such that the de-duplication is applied for a volume for which a high capacity-reduction effect is provided by the de-duplication processing, and in contrast, the de-duplication is not applied to maintain performance for a volume for which a low capacity-reduction effect is provided by the de-duplication processing.

摘要： There is provided a computer system comprising a first storage system and a second storage system coupled to the first storage system. The first storage system provides a first storage area. The second storage system provides a second storage area. The second storage system reads and writes the requested data from and to the first storage area associated with the second storage area; specifies the first storage area associated with the second storage area from which the data is to be erased upon reception of a request for erasing the data stored in the second storage area; and transmits the request for erasing the data to the first storage system providing the specified first storage area. The first storage system erases the data stored in the specified first storage area, based on a data erasure condition included in the request for erasing the data.

摘要： A processor of a storage controller receives an erasure process request relating to data stored in a storage unit, from a host computer, via a data I/O interface, detects a logical storage extent which is different to the logical storage extent allocated to the storage unit and which can be allocated, allocates the logical storage extent thus detected to the storage unit, sends a notification indicating that access to the storage unit is possible, to the host computer which is the source of the request, and then executes erasure of the data in the logical storage extent that is associated with the storage unit forming the erasure object, and sends a data erasure notification to the management computer when the data has been erased.

摘要： A storage subsystem includes: a controller; a first logical storage area corresponding to a RAID group configured by a plurality of storage devices; and a second logical storage area corresponding to a plurality of the RAID groups each configured by the plurality of storage devices, and storing a copy of data stored in the first logical storage area. In the storage subsystem, the first and second logical storage areas form a copy group, and for starting copying from the first to second logical storage area, the controller performs a mode change, from a power saving mode to a ready mode, to the plurality of storage devices configuring the plurality of RAID groups corresponding to the second logical storage area. With such a storage subsystem, the time can be reduced for activating copy-destination storage devices to which a power saving function is applied, and the copy time is thus favorably reduced.
