Abstract
The present invention aims at providing a storage subsystem capable of improving a backend-side I/O processing performance and enabling a single semiconductor memory adapter to be replaced at a time. Therefore, the present invention provides one or more semiconductor memory adapter boards mounting semiconductor memories each having smaller capacity than SSDs attached detachably to a drive canister, a wide port connection established to access the semiconductor memories, the semiconductor memories used as a read cache area of HDDs, and further adopts a wind direction control structure for ensuring a cooling wind path to the HDDs when an adapter board is attached.
