US 2016/0259594 A1 · STORAGE CONTROL DEVICE AND STORAGE SYSTEM

Abstract

A storage control device includes a first storage device and a processor. The first storage device stores management information used for managing a variable area of storage regions of a second storage device in a storage apparatus. Each storage region is allocated to a main area or a spare area. The variable area includes storage regions allocated to the spare area and allocatable to the main area. The processor acquires, from the storage apparatus, information on numbers of times of Read processing on the second storage device and numbers of times of Write processing on the second storage device, and notifies the storage apparatus, when a number of times of Read processing on the second storage device within a predetermined time period is larger than a predetermined threshold, of a request for allocating a first portion of the variable area to the main area on basis of the management information.

Dependent claims

A storage control device, comprising:

a first storage device configured to
store therein management information used for managing a variable area of storage regions provided to a second storage device included in a storage apparatus, the storage regions each being allocated to either one of a main area and a spare area, the variable area including storage regions allocated to the spare area and allocatable to the main area, the main area being used for storing data, the spare area serving as a reserve area of the main area;
and
a processor configured to
acquire, from the storage apparatus, information on numbers of times of Read processing on the second storage device and numbers of times of Write processing on the second storage device, and
notify the storage apparatus, when a number of times of Read processing on the second storage device within a predetermined time period is larger than a first predetermined threshold, of a request for allocating a first portion of the variable area to the main area on basis of the management information.

3 more elements

A storage system, comprising:

a storage apparatus including:
a storage device provided with
storage regions each allocated to either one of a main area used for storing data and a spare area serving as a reserve area of the main area, and
a second processor configured to
allocate a first portion of a variable area of the storage regions to the main area upon receiving a first request for allocating the first portion to the main area, the variable area including storage regions allocated to the spare area and allocatable to the main area;
and
a storage control device including:
a first processor configured to
acquire, from the storage apparatus, information on numbers of times of Read processing on the storage device and numbers of times of Write processing on the storage device, and
notify the storage apparatus, when a number of times of Read processing on the storage device within a predetermined time period is larger than a first predetermined threshold, of the first request on basis of management information used for managing the variable area.

7 more elements

A computer-readable recording medium having stored therein a program that causes a computer to execute a process, the process comprising:

acquiring, from a storage apparatus, information on numbers of times of Read processing on a storage device included in the storage apparatus and numbers of times of Write processing on the storage device, the storage device being provided with storage regions each allocated to either one of a main area used for storing data and a spare area serving as a reserve area of the main area;
and
notifying the storage apparatus, when a number of times of Read processing on the storage device within a predetermined time period is larger than a first predetermined threshold, of a request for allocating a first portion of a variable area of the storage regions to the main area on basis of management information, the variable area including storage regions allocated to the spare area and allocatable to the main area.
