Abstract: A primary site includes a volume #1 that stores data, and copies first backup data that is backup data of data corresponding to the volume #1 to a secondary site. In the failover process of handing over the execution of a transaction process from the primary site to the secondary site, a cloud management node restores the volume #1 to a storage system as a volume #2 based on the first backup data copied to the secondary site. The cloud management node manages the first backup data, as second backup data, that is backup data of data corresponding to the volume #2.

Abstract: A plurality of server computers shares a virtualized namespace. A storage controller provides a virtual storage area shared by a first server computer and a second server computer. A server computer that is each of the first server computer and the second server computer stores a program that issues an NVM-Express command that is a command conforming to an NVM-Express standard. The program allows the server computer to access the virtual storage area via the PCI-Express by issuing the NVM-Express command specifying a namespace associated with the virtual storage area. The storage controller allocates a storage area in a nonvolatile memory device to the virtual storage area based on the access.

Abstract: A storage device includes one or more FMPKs including a FM chip capable of storing data and a storage controller that controls storing of write data of a predetermined write request for the FMPK. The FMPK includes a compression/decompression circuit that compresses data according to a second compression algorithm different from a first compression algorithm. The storage controller compresses data using the first compression algorithm, and determines whether the write data will be compressed using the storage controller or the compression/decompression circuit based on a predetermined condition. The write data is compressed by the determined storage controller or compression/decompression circuit and is stored in the FMPK.

Abstract: A storage device allocates an address area of an address space to the first virtual address space in accordance with writing onto a first virtual address space. A controller manages an address area in the first virtual address space, in which address area a mapping to the real address space has been removed, as a usage prohibition area. When a use state of the first virtual address space reaches a predetermined criterion, the controller or the storage device adds new continuous address areas to the first virtual address space to expand the first virtual address space. The storage device allocates an area, in which a mapping to the first virtual address space has been removed, to the first virtual address space expanded.
