    • In one embodiment of the invention, a disk storage accessing system for enabling a plurality of computers to share and access a plurality of disk storages comprises a plurality of computers that refer to the disk storages. Each of the computers includes a counting module for counting a frequency of accesses to each of the disk storages, and a module for receiving an access path change command to change access paths for the computer to access a different disk storage according to the command. The system further comprises an instructing module for collecting and totaling a frequency of accesses to each disk storage, as counted by the counting module of each of the computers, as well as instructing a particular disk storage as a copy source disk storage to copy content in the copy source disk storage into one or more other disk storages as one or more target disk storages when the totaled access frequency is higher than a predetermined value, and for instructing the receiving module of a computer that accesses the copy source disk storage after receiving a report of copy completion, to change access paths so as to access a target disk storage instead of the copy source disk storage.
    • 在本发明的一个实施例中,用于使多个计算机能够共享和访问多个磁盘存储器的磁盘存储访问系统包括指代磁盘存储器的多个计算机。 每个计算机包括用于计数对每个磁盘存储器的访问频率的计数模块,以及用于接收访问路径改变命令的模块,用于根据该命令改变计算机访问不同磁盘存储器的访问路径。 该系统还包括一个指令模块,用于收集和总计每个磁盘存储器的访问频率,如由每个计算机的计数模块所计数,以及指示特定的磁盘存储器作为复制源磁盘存储器以复制内容 所述复制源磁盘在总共访问频率高于预定值时存储到一个或多个其他磁盘存储器中作为一个或多个目标磁盘存储器,并且用于指示在接收到所述复制源磁盘存储器之后访问所述复制源磁盘存储器的计算机的接收模块 报告复制完成,更改访问路径,以访问目标磁盘存储,而不是复制源磁盘存储。

    • A management computer includes a memory storing toplogical information including identifiers of ports of computers, storage apparatuses, and switches. The management computer includes a processor, which is configured to: collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses; evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range; search a first access path to which the certain access time corresponds; search at least one second access path starting from a first computer port on the first access path; and search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.
    • 管理计算机包括存储包括计算机,存储设备和交换机的端口的标识符的拓扑信息的存储器。 管理计算机包括处理器,其被配置为:收集端口的多个性能信息,以及从计算机端口到存储装置的多个访问时间; 评估多个访问时间中的某个访问时间超过预定的允许范围; 搜索特定访问时间对应的第一访问路径; 搜索从第一访问路径上的第一计算机端口开始的至少一个第二访问路径; 以及搜索位于所述至少一个第二访问路径上的特定端口的性能信息,以便显示所搜索的性能信息。
