摘要： There is provided a storage subsystem having a virtual volume and a page volume which has a page physical area allocated to the virtual volume. The storage subsystem divides an address space of the virtual volume into a plurality of pages, classifies each of the pages into one of a plurality of states including at least a first state and a second state, and further divide a page which is classified into the second state into a plurality of segments to managed the page classified into the second state. The first state is a state in which a page physical area is allocated to the page from the page volume, and the write data is stored in the page physical area. The second state is a state in which the predetermined pattern data and the segment are managed, in the memory, by correlating with each other.

摘要： A storage controller comprises a cache storage used as a cache of an external storage and a control processor coupled to the cache storage. The control processor comprises an internal access function and an external access function. The internal access function transmits a read command to the cache storage. The cache storage determines whether the read target data complying with the read command is stored in a physical storage device or not. If the result of the determination is negative, the external access function is executed while, if the result of the determination is positive, the external access function is not executed because the cache storage transmits the read target data to the internal access function without issuing a request to the external access function.
摘要翻译：存储控制器包括用作外部存储器的高速缓存的高速缓存存储器和耦合到高速缓冲存储器的控制处理器。控制处理器包括内部访问功能和外部访问功能。内部访问功能将读取命令发送到缓存存储。高速缓冲存储器确定符合读取命令的读取目标数据是否存储在物理存储设备中。如果确定结果为否定，则执行外部访问功能，如果确定结果为肯定，则不执行外部访问功能，因为高速缓存存储器将读取的目标数据发送到内部访问功能而不发出请求外部访问功能。
