    • 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.
    • 提出了一种存储装置及其控制方法,其能够在覆盖闪存的缺点的同时执行省电操作,例如寿命短并且需要很多时间来重写数据。 该存储装置将由多个非易失性存储器中的每一个提供的存储区域作为池进行管理,向主计算机提供虚拟卷,根据来自主计算机的数据写入请求动态地将虚拟池中的存储区域分配给虚拟卷 用于将数据写入虚拟卷,并将数据放置在分配的存储区域中。 此外,存储装置将来自主计算机的数据的放置目的地集中到由某些非易失性存储器提供的存储区域,并停止对未使用的非易失性存储器的电源,监视数据重写计数和/或访问频率以存储 由非活动性存储器提供的区域,如果数据重写计数增加则将数据迁移到另一个存储区域,并且如果访问频率变得过大,则分发数据放置目的地。

    • 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.
    • 提供了一种用于解决问题的存储系统,其中当不存在用户的注册被删除时,只有系统管理员才能访问用户离开的文件,使得在审核时放置在管理员上的负载增加。 用于允许尝试登录到存储系统的用户访问存储系统中记录的文件的认证程序,该程序包括:从用户接收用户名和密码的第一步骤; 用于参考对应于存储系统中记录的一对用户名和密码的有效期的第二步骤; 以及第三步骤,用于允许用户基于第二步骤的结果访问对应于有效期的文件,第一至第三步骤由处理器执行。

    • 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.
    • 本发明使得即使在复制期间也可以访问文件,同时保持其一致性。 在多个分布式存储设备之间进行复制,响应于来自客户端机器#11的访问请求,从GUID管理数据库13,23搜索文件,每个GUID管理数据库存储存储的文件的GUID之间的关系 在存储装置#0(#1)和包含原始文件的存储装置的装置ID中。 当存储装置#1没有请求文件时,根据文件C的GUID和从文件C所要求的文件C,从GUID管理数据库中搜索包含其原始文件的存储装置的装置ID(#0) 这可以访问存储设备#0。

    • 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.
    • 公开了一种用于控制高速缓冲存储器的分割区域的盘系统。 表示要访问的数据是用户数据还是元数据的标识信息被添加到从CPU发出的每个I / O命令。 磁盘控制器在接收到这样的I / O命令时,根据识别信息从设置在高速缓冲存储器中的多个虚拟区域中选择目标虚拟区域。 当执行I / O命令时将新数据存储在高速缓冲存储器中时,磁盘控制器与新数据对应地记录高速缓冲存储器中所选择的虚拟区域的编号。 针对每个高速缓存区域独立地执行高速缓存数据替换,从而可以保持每个高速缓冲存储器区域的预定上限大小。
