Abstract
The present invention makes it possible to maintain availability and scale out file performance, while suppressing costs. A unified storage has a plurality of controllers and a storage apparatus (storage device unit), and each of the plurality of controllers is equipped with one or more main processors (CPU) and one or more channel adapters (FE-I/F). Each main processor causes a block storage control program to operate and thereby process data inputted to and outputted from the storage apparatus, each channel adapter has a processor (CPU) that performs transmission and reception to and from a main processor after receiving an access request, and the processors in the plurality of channel adapters cooperate to cause a distributed file system to operate, and distributively store data, written as a file, to the plurality of controllers.
