Abstract: A storage system in which a cluster is configured by a plurality of storage nodes is configured to include: a management server configured to store a template including an OS of a storage node, a process program that configures a process, and an installer; a maintenance node VM configured to collect configuration information required for configuring a restore-target storage node from within the storage system; a maintenance node, a management server, and a hypervisor configured to create a VM for a new storage node on the basis of the template and the configuration information; and a cluster controller configured to create a process in the new storage node using the installer and restore the process to a state corresponding to the process of the restore-target storage node.

Abstract: This computer system is configured by connecting a plurality of computers via a communication network. At least one computer among the computers has a storage device and a communication device. The communication device has: a controller that controls data transmission/reception via the communication network; and an intermediate memory that stores data transmitted/received between the storage device and other calculators on the communication network.

Abstract: The present invention provides a storage system capable of preventing data loss when power failure or other failures occur to an external power supply, by determining whether the capacity corresponding to the write data can be saved from a volatile memory to a nonvolatile memory based on a charged capacity of a battery used as an internal power supply and a non-backed-up (not yet backed-up) data capacity from the volatile memory to the nonvolatile memory, when storing data from a host computer or a system drive to the volatile memory of the storage system. If it is determined that saving of data is possible, an area corresponding to the write data capacity is allocated in the volatile memory and data is written to the allocated area, but if it is determined that saving of data is not possible, the writing of data is suppressed.
