Abstract
In conventional unified storage systems, an I/O for block storage and an I/O for file storage are processed in a single OS without being distinguished, so that it was not possible to perform processes for speedy failure detection or for enhancing performances such as tuning of performance by directly monitoring hardware. The present invention solves the problem by having a block storage-side OS and an OS group managing multiple systems including a file system other than the block storage-side OS coexist within a storage system, wherein the OS group managing multiple systems including a file system other than the block storage-side OS is virtualized by a hypervisor, wherein a block storage micro-controller and the hypervisor can cooperate in performing processes.
