Abstract:
1. A storage control system, comprising: a storage control device being adapted to manage a plurality of storage pools each comprising a plurality of logical storage devices and being adapted to manage a plurality of storage areas in each of the plurality of storage pools, the plurality of logical storage devices being prepared on one or more RAID (Redundant Array of Inexpensive Disks) groups by management of the storage control device; wherein the storage control device is adapted to provide a first logical unit, which can be accessed by one of a plurality of external terminals and is associated with a first pool of the plurality of storage pools; wherein the storage control device is adapted to provide a second logical unit, which can be accessed by one of the plurality of external terminals and is associated with a second pool of the plurality of storage pools; wherein the storage control device is adapted to receive a first write request directed to the first logical unit, and in response to receiving the first write request, is adapted to allocate, if necessary, a first storage area in the first pool of the plurality of storage pools to the first logical unit identified by the first write request to be able to store data of the first write request, and wherein the storage control device is adapted to receive a second write request directed to the second logical unit, and in response to receiving the second write request, is adapted to allocate, if necessary, a second storage area in the second pool of the plurality of storage pools to the second logical unit identified by the second write request to be able to store data of the second write request.
