Abstract

Provided is a storage device system capable of being connected on a plurality of different types of networks. Also provided are a storage device control system and a method of controlling activation of the storage device system which are needed to invent the storage device system. A storage device system in accordance with the present invention comprises: a plurality of storage devices in which information is stored; a storage device control section that controls storage of information in the plurality of storage devices; and a connection unit connected to the storage device control section. Furthermore, the storage device system comprises a first communication control section that includes: a first processor which is connected to the storage device control section via the connection unit and also connected on a first network external to the storage device system, which converts information of a first form received over the first external network into information of a second form, and which issues a request for access to the plurality of storage devices; and a second processor which accesses the plurality of storage devices via the connection unit and the storage device control section in response to the access request issued from the first processor, and which controls activation of the first processor.
