摘要： A storage device system in which migration of data from an existing storage device to a higher-standard storage device is unnecessary, and in which discarding of existing storage devices by the user can be prevented. A CHF 61 receives a Read Capacity command from a new-type storage device 25 (S101). Using LDEV, LUN and other information tables, an LUN 87 is converted into a mapped LDEV (S102). A check is performed to determine whether the LDEV emulation type is read-only, write-only, or read/write (S103). If none of these, a check is performed to determine whether the emulation type is newly created (S104). If newly created, the size of all storage areas of the LDEV are set as the Max LBA in a response to the new-type storage device 25 (S105). If the result of S103 is YES, the size of the user area in the LDEV is set as the Max LBA in a response to the new-type storage device 25 (S106). If not newly created, processing proceeds to the processing of S106.

摘要： A storage controller of the present invention writes data to a storage device, in which the storage unit is fixed, at a size that is larger than this storage unit, and curbs response performance degradation. A host sends write-data in a prescribed number of logical blocks in accordance with a basic I/O size defined at initialization. A controller respectively creates a guarantee code for each logical block, and appends same to the write-data. Write-data, to which a guarantee code has been appended, is stored in another prescribed number of logical blocks in accordance with a basic disk access size which is set at a value corresponding to the basic I/O size, and sent to a storage device. When an unused part is also stored in the storage device, the utilization efficiency of the storage area decreases, but the need to read out data located before and after data targeted for updating at data write is eliminated, thereby curbing the degradation of response performance.
摘要翻译：本发明的存储控制器将数据写入存储单元固定的存储设备，其尺寸大于该存储单元，并且抑制响应性能下降。主机根据初始化时定义的基本I / O大小，在规定数量的逻辑块中发送写入数据。控制器分别为每个逻辑块创建一个保证代码，并将其附加到写入数据。根据设置在与基本I / O尺寸相对应的值的基本磁盘访问大小，将存储有附加了保证码的写数据存储在另一规定数量的逻辑块中，并发送到存储器设备。当未使用的部分也存储在存储装置中时，存储区域的利用效率降低，但是消除了在数据写入期间用于更新的数据之前和之后读出数据的需要，从而抑制响应性能的劣化。

摘要： A storage apparatus is capable of relocating volumes accurately even when a plurality of storage apparatuses are connected. The storage apparatus comprises an external connection function for recognizing an external logical volume set on a physical storage device as a logical volume inside the storage apparatus, a storage control device with a volume relocation function for relocating the logical volumes based on set conditions, and a storage unit with a plurality of physical storage devices. When the host sends a read request to the logical volume set on the physical storage device of the storage unit, the volume relocation function generates internally the same read request to the external storage volume set on the physical storage device in the external storage apparatus and relocates volumes based on the monitor information obtained by monitoring responses to the read request.

摘要： Proposed is a storage system capable of preventing the compression of a cache memory caused by data remaining in a cache memory of a storage subsystem without being transferred to a storage area of an external storage, and maintaining favorable I/O processing performance of the storage subsystem. In this storage system where an external storage is connected to the storage subsystem and the storage subsystem provides a storage area of the external storage as its own storage area, provided is a volume for saving dirty data remaining in a cache memory of the storage subsystem without being transferred to the external volume. The storage system recognizes the compression of the cache memory, and eliminates the overload of the cache memory by saving dirty data in a save volume.
