Abstract
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.
Claims15
A storage control device comprising:
- 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.
A computer-implemented storage control method comprising:
- acquiring 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;
- detecting 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
- executing redundant copy of the detected first storage device.
A non-transitory computer-readable medium storing a storage control program that causes a computer to execute a process comprising:
- acquiring 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;
- detecting 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
- executing redundant copy of the detected first storage device.
