摘要： It is necessary to install a program called an agent in order to keep track of how much a file system on a computer uses a disk. On this account, loads might be applied to a server due to installation work or the agent program to increase primary costs. In addition, software inside a storage device determines and records a target block for data input/output and keeps track of capacity utilization, which might degrade the input/output performance of the storage device. A computer system is provided in which configuration information and operating information are acquired from a storage device, when data input/output is made from a computer to a logical unit, it is determined that the computer uses the logical unit to which input/output is made, and capacity used by the computer is computed.

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： According to this invention, a computer system has a host computer, a first storage subsystem providing a first volume, a second storage subsystem providing a second volume for storing a copy of data stored in the first volume. The computer system stores copy configuration information including correspondence between the first volume and the second volume. The management computer transmits the data erasure request to the first storage subsystem upon reception of a first data erasure request for erasing the first volume. The first storage subsystem stops a copying process of data stored in the first volume to the second volume, transmits a second data erasure request for erasing the second volume to the second storage subsystem, and erases the data stored in the first volume. Thus, in the case of erasing data stored in a storage area, corresponding data stored in a destination storage area is also erased so that security risks can be reduced.
摘要翻译：根据本发明，计算机系统具有主计算机，提供第一卷的第一存储子系统，提供用于存储存储在第一卷中的数据的副本的第二卷的第二存储子系统。计算机系统存储包括第一卷和第二卷之间的对应关系的复制配置信息。管理计算机在接收到用于擦除第一卷的第一数据擦除请求时，向第一存储子系统发送数据擦除请求。第一存储子系统停止将存储在第一卷中的数据复制到第二卷，将第二数据擦除请求发送到第二存储子系统，并擦除存储在第一卷中的数据。因此，在擦除存储在存储区域中的数据的情况下，存储在目的地存储区域中的对应数据也被擦除，从而可以降低安全风险。

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.

摘要： To prevent, when data is erased from a storage system that stores differential of updated data, a large amount of differential data from being created, a storage subsystem provides a first storage area which stores data, and includes a second storage area which stores a replication of data stored in the first storage area. When the data stored in the first storage area is updated, the data is replicated to the second storage area before the data is updated. When a request to erase the data stored in the first storage area is received, replication of unupdated data to the second storage area is suspended and the data stored in the first storage area is erased based on the request to erase the data.
