    摘要: Proposed are a storage apparatus and its control method capable of performing power saving operations while covering the shortcomings of a flash memory such as the life being short and much time being required for rewriting data. This storage apparatus manages the storage areas provided by each of multiple nonvolatile memories as a pool, provides a virtual volume to a host computer, dynamically allocates the storage area from a virtual pool to the virtual volume according to a data write request from the host computer for writing data into the virtual volume, and places the data in the allocated storage area. In addition, the storage apparatus centralizes the placement destination of data from the host computer to a storage area provided by certain nonvolatile memories and stop the power supply to the nonvolatile memories that are unused, monitors the data rewrite count and/or access frequency to storage areas provided by the nonvolatile memories that are active, migrates data to another storage area if the data rewrite count increases, and distributes the data placement destination if the access frequency becomes excessive.

    摘要: A cache control apparatus is provided in a computer system including an access source and a storage apparatus. This device, based on I/O status information, which is information denoting the I/O status in accordance with an I/O command from the access source, determines whether or not the I/O performance from the access source drops. In a case where the result of this determination is affirmative, the cache control apparatus changes a cache utilization status specified from cache utilization status information, which is information denoting the cache utilization status related to a cache area, to a cache utilization status that improves I/O performance.

    摘要: Provided is a storage system for solving the problem in that, when the registration of a nonexistent user is deleted, only a system administrator can access files that the user left, so that a load placed on the administrator increases at the time of an audit. The authentication program for permitting a user, who is attempting to log in to a storage system, to access a file recorded in the storage system, the program including: a first step for receiving a user name and a password from the user; a second step for referring to a validity term corresponding to a pair of the user name and the password recorded in the storage system; and a third step for permitting access by the user to a file corresponding to the validity term based on a result of the second step, the first to third steps being executed by a processor.

    摘要: A volume group comprising one or a plurality of logical volumes is set. A coexistence avoidance volume group having different array groups can be set to the volume group. Upon execution of preset volume search criteria, a logical volume is specified by carrying out a search in which are excluded array groups to which logical volumes in the coexistence avoidance volume belong.

    摘要: This invention enables a file to be accessed even during replication while maintaining its consistency. The replication is done among a plurality of distributed storage devices, a file is searched, in response to an access request from a client machine #11, from GUID management databases 13, 23 each of which stores a relationship between a GUID of a file stored in a storage device #0 (#1) and a device ID of a storage device containing an original file. When the storage device #1 does not have the demanded file, a device ID (#0) of a storage device containing its original file is searched from the GUID management database based on a GUID of the file C, and the file C demanded by this the storage device #0 is accessed.

    摘要: Disclosed is a disk system for controlling divided areas of a cache memory. Identification information that denotes whether data to be accessed is user data or meta data is added to each I/O command issued from a CPU. A disk controller, when receiving such an I/O command, selects a target virtual area from among a plurality of virtual areas set in the cache memory according to the identification information. When new data is to be stored in the cache memory upon the execution of the I/O command, the disk controller records the number of the selected virtual area in the cache memory in correspondence with the new data. A cache data replacement is executed independently for each cache area, thereby a predetermined upper limit size of each cache memory area can be kept.
