摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

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： 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.
