摘要： A virtual storage system is equipped with a plurality of storage systems and a virtualization device for virtualizing the plurality of storage systems logically into a single storage resource provided to a host computer. When one of the storage systems receives a command from the host computer, in the event that the storage system itself is not in possession of a function corresponding to the command, the storage system retrieves a storage system in possession of a function corresponding to the command and transfers this command to the storage system in possession of the function corresponding to the command.

摘要： If an I/O load on a first virtual storage area falls below a first threshold, a controller copies data in a first storage area, which is allocated to the first virtual storage area, to a third storage area in a second tier storage area, and allocates the third storage area instead of the first storage area to the first virtual storage area. If an I/O load on a second virtual storage area exceeds a second threshold which is greater than said first threshold, the controller copies data in a second storage area, which is allocated to the second virtual storage area, to a fourth storage area in a first tier storage area, and allocates the fourth storage area instead of the second storage area to the second virtual storage area.
摘要翻译：如果第一虚拟存储区域上的I / O负载低于第一阈值，则控制器将分配给第一虚拟存储区域的第一存储区域中的数据复制到第二层存储区域中的第三存储区域，并且将第三存储区域而不是第一存储区域分配给第一虚拟存储区域。如果第二虚拟存储区域上的I / O负载超过大于所述第一阈值的第二阈值，则控制器将分配给第二虚拟存储区域的第二存储区域中的数据复制到第二存储区域中的第四存储区域第一层存储区域，并且将第四存储区域而不是第二存储区域分配给第二虚拟存储区域。
