摘要： The storage system of the present invention preserves data long-term by using memory devices such as flash memory devices. A flash memory mounting unit of a storage apparatus has a plurality of flash memory devices. Logical devices are set up in the storage region of the flash memory devices. A start-up scheduler controls start-up of internal refresh processing and external refresh processing. A refresh function management table respectively manages the method of refreshing the data stored in the flash memory devices and the refresh time, for each logical device. The start-up scheduler, on discovering that a logical device has reached its refresh period, sends a start-up command to the storage apparatus or external apparatus, to start-up internal refresh processing or external refresh processing.

摘要： A storage apparatus installed in a first site generates a snapshot of a copy source logical device in an intermediate logical device. Next, an external storage apparatus including a logical device corresponding to the intermediate logical device is disconnected from the first site and connected to the second site. A storage apparatus in the second site is made to recognize the logical device in the external storage device as a logical device of a remote copy target. Next, the storage apparatus instructs the second site about writing in the copy target logical device through a global network on the basis of the difference data managed with the bit map.

摘要： Availability of an information system including a storage apparatus and a host computer is improved. A host system includes a first storage apparatus provided with a first volume for storing data, and a second storage apparatus for storing the data sent from the first storage apparatus. In case of a failure occurring in the first storage apparatus, the host sends the data to be sent to the first storage apparatus to the second storage apparatus.
