More Information
Summary:A storage control device includes circuitry configured to acquire status information indicating a load status and a response status of each of one or more storage devices from the one or more storage devices which are accessed in response to a request transmitted from a host device, detect a first storage device having a load no more than a first threshold value and a response time no less than a second threshold value from the one or more storage devices on the basis of the acquired status information, and execute redundant copy of the detected first storage device.
