    • 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.
    • 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。

    • A computer system is provided that is capable of reducing an administrator's operational errors by connecting a new server to a SAN and automating a SAN boot setting, and capable of lightening the administrator's task of checking for a wrong connection by detecting a wrong connection made when a new server is connected to an SNW connection device. Once a new server connected to a PnP SAN starts with a boot program obtained from a boot management server, the new server transmits configuration information on the new server to a resource management server. In response to a request from the resource management server, a storage device refers to PnP SAN information to transmit SAN information on a storage network connection device to which the new server is connected. The resource management server determines to add the new server to a resource group on the basis of the SAN information and requirement information. The resource management server sets the storage device and the new server for SAN-booting the new server.
    • 提供了一种计算机系统,其能够通过将新服务器连接到SAN并自动执行SAN引导设置来减少管理员的操作错误,并且能够通过检测错误的连接来减轻管理员检查错误连接的任务 新服务器连接到SNW连接设备。 一旦连接到PnP SAN的新服务器从从引导管理服务器获取的引导程序开始,新服务器将新服务器上的配置信息传输到资源管理服务器。 响应于资源管理服务器的请求,存储设备参考PnP SAN信息,以在连接新服务器的存储网络连接设备上传输SAN信息。 资源管理服务器根据SAN信息和需求信息确定将新服务器添加到资源组。 资源管理服务器设置SAN的存储设备和新服务器,引导新的服务器。

    • 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.
    • 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。

    • 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.
