An internal device () is implanted in a living body (). A control section () causes a communication section () to wirelessly transmit data corresponding to electroencephalogram signals of the living body () which are detected through a group of N (N is 2 or more) electrodes, to an external device (). When the communication section () receives a designation signal designating a group of M electrode(s) (), M being smaller than N, the communication section () is caused to transmit data corresponding to electroencephalogram signals of the living body () which are detected through the group of M electrode(s) (), to the external device () in real time.

With a RAID group not configured from a plurality of storage devices, a storage area of a storage device is provided directly to a virtual volume instead of providing a logical volume inside the RAID group to the virtual volume. That is, the storage system, upon receiving a write request with respect to a virtual storage area, first, specifies a data redundancy configuration (the number of data partitions and the number of created parities) and a RAID level set to a virtual volume including this virtual storage area. The storage system selects storage devices in the numbers in accordance with the specified RAID level and redundancy configuration for this virtual storage area. The storage system selects, from among the selected storage devices, a storage area that is not allocated to any virtual storage area, and allocates this storage area to this virtual storage area. The storage system partitions the data and writes this data together with the parity to this allocated storage area.

Storage system

The storage system is coupled to a host apparatus and includes a plurality of storage devices, each of which includes a plurality of real pages, and a controller. The controller is configured to: manage the plurality of storage devices as a pool; provide a virtual volume to the host apparatus, the virtual volume including a plurality of virtual pages to each of which a portion of the pool is allocated in accordance with a write command; distribute data written in a first virtual page to a first group of real pages, the first group of real pages making up a redundant array and being selected from different storage devices; and migrate data stored in a first real page, which is a real page of the first group and belongs to a first storage device, to another storage device without migrating data stored in another real page of the first group.
