    摘要: A storage control apparatus of the present invention is able to duplicatively manage data in a cache memory even during maintenance work. When a memory package CMPK3 specified by a user is removed from the apparatus 1 (S2), a microprocessor 2 changes a pair that has been configured using CMPK2 and CMPK3 to a pair of CMPK2 and a free area of a CMPK1. As a result, received data (S5) is respectively written to multiple cache memories (S6, S7), and duplicatively managed.

    摘要: It is provided a storage system for storing data requested by a host computer to be written, the storage system comprising: at least one processor, a cache memory and a cache controller. The cache memory includes a first memory which can be accessed by way of either access that can specify an access range by a line or access that continuously performs a read and a write. The cache controller includes a second memory which has a higher flexibility than the first memory in specifying an access range. The cache controller determines an address of an access destination upon reception of a request for an access to the cache memory from the at least one processor, and switches a request for an access to a specific address into an access to a corresponding address in the second memory.

    摘要: A storage apparatus sets up part of non-volatile cache memory as a cache-resident area, and in an emergency such as an unexpected power shutdown, backs up dirty data of data cached in volatile memory to an area other than the cache-resident area in the non-volatile cache memory, together with the relevant cache management information. Further, the storage apparatus monitors the amount of the dirty data in the volatile cache memory so that the dirty data cached in the volatile cache memory is reliably contained in a backup area in the non-volatile memory, and when the dirty data amount exceeds a predetermined threshold value, the storage apparatus releases the cache-resident area to serve as the backup area.

    摘要: A disk array subsystem makes a diagnosis of a memory device while maintaining performance of a normal access to the memory device contained in a controller, thus enhancing reliability of the memory data. In the disk array subsystem having a disk drive and a controller, the controller has a cache unit and the cache unit has a memory device and a memory control unit. The memory control unit monitors status of memory access by means of a memory access state monitoring unit, issues a diagnosis request while normal access is not made to the memory device, makes access to the memory device for diagnosis of the memory data, and checks the data read from the memory device by using ECC and detects a data error.
