Abstract
According to certain aspects, the presently disclosed subject matter includes a method, system and apparatus, for managing a plurality of disk drives in a storage system. The workload of at least one disk drive among the plurality of disk drives is monitored, wherein the monitoring comprises receiving data indicative of a temperature of the at least one disk drive. In case the measured temperature matches a predefined criterion, the modification of workload distribution across the plurality of disk drives is enabled, in order to reduce workload of the at least one disk drive.
Claims22
A storage system comprising a storage control layer operatively coupled to a plurality of disk drives, said storage control layer comprising at least one processor operable:
- to receive data indicative of a temperature of at least one disk drive among said plurality of disk drives, wherein said temperature is indicative of workload of said at least one disk drive;
- and
- responsive to receiving a temperature matching a predefined criterion, to enable modification of workload distribution across said plurality of disk drives in order to reduce a workload of said at least one disk drive.
A method of managing a plurality of disk drives in a storage system, the method comprising:
- monitoring a workload of at least one disk drive among said plurality of disk drives, wherein the monitoring comprises receiving data indicative of a temperature of said at least one disk drive;
- and
- responsive to matching said temperature to a predefined criterion, enabling modification of workload distribution across said plurality of disk drives in order to reduce workload of said at least one disk drive.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform a method of managing a plurality of disk drives in a storage system, the method comprising:
- monitoring a workload of at least one disk drive among said plurality of disk drives, wherein monitoring comprises obtaining data indicative of a temperature of said at least one disk drive;
- to determining whether said data indicative of a temperature, matches said predefined criterion;
- and
- responsive to matching said temperature to a predefined criterion, enabling modification of workload distribution across said plurality of disk drives in order to reduce workload of said at least one disk drive.
A workload management unit operatively connected to a storage control layer comprising at least one processor in a storage system, the control layer being operatively coupled to a plurality of disk drives, workload management unit operable:
- to receive data indicative of a temperature of at least one disk drive among said plurality of disk drives, wherein said temperature is indicative of workload of said at least one disk drive;
- and
- responsive to the receiving a temperature matching a predefined criterion, to enable modification of workload distribution across said plurality of disk drives in order to reduce workload of said at least one disk drive.
