Abstract

See full text

An object of the present invention is to properly secure the consistency of data while suppressing a processing load of a controller on a processor. A storage system includes a plurality of controllers and an HCA that can directly access a memory and can communicate with the controllers. The controller includes a CPU, and a memory having a buffer region into which data is temporarily stored and a cache region into which data is cached. In the case where new data according to a write request is stored into the buffer region, the CPU of the controller sequentially transfers the new data to the cache regions using the HCA without passing through the other buffer regions.
