    • A cache configuration management system capable of lightening workloads of estimation of a cache capacity in virtualization apparatus and/or cache assignment is provided. In a storage system having application servers, storage devices, a virtualization apparatus for letting the storage devices be distinctly recognizable as virtualized storages, and a storage management server, the storage management server predicts a response time of the virtualization apparatus with respect to a application server from cache configurations and access performances of the virtualization apparatus and storage device and then evaluates the presence or absence of the assignment to a virtual volume of internal cache and a predictive performance value based on a to-be-assigned capacity to thereby perform judgment of the cache capacity within the virtualization apparatus and estimation of an optimal cache capacity, thus enabling preparation of an internal cache configuration change plan.
    • 提供了能够减轻虚拟化装置和/或高速缓存分配中的高速缓存容量的估计工作量的高速缓存配置管理系统。 在具有应用服务器,存储装置,用于使存储装置能够被识别为虚拟化存储的虚拟化装置和存储管理服务器的存储系统中,存储管理服务器预测虚拟化装置相对于应用服务器的响应时间 从虚拟化装置和存储装置的缓存配置和访问性能,然后基于分配的容量来评估对虚拟卷的内部高速缓存的分配的存在或不存在以及预测性能值,从而执行对 虚拟化设备内的高速缓存容量和最佳高速缓存容量的估计,从而能够准备内部缓存配置更改计划。
