Abstract
Embodiments of the present disclosure provide a solution of evaluating a rebuilding performance of a redundant array of independent disks. In some embodiments, there is provided a computer-implemented method, comprising: simulating, based on a first group of redundant arrays of independent disks, a rebuilding process for a second group of redundant arrays of independent disks; obtaining a first performance metric of the simulated rebuilding process; and identifying a factor associated with the rebuilding performance of the second group of redundant arrays of independent disks based on the first performance metric.
Claims18
A computer-implemented method, comprising:
- simulating, using a first group of redundant arrays of independent disks (RAID), at least one input output generator, and one or more spare disks, a rebuilding process for a second group of redundant arrays of independent disks;
- obtaining a first performance metric, of a plurality of performance metrics, of the simulated rebuilding process;
- identifying, based on the first performance metric, a factor associated with rebuilding performance of the second group of redundant arrays of independent disks;
- and
- re-simulating the rebuilding process for the second group of redundant arrays of independent disks by changing at least one of the following:
- a number of the input output generators, and a number of the one or more spare disks.
An electronic device, comprising:
- at least one processing unit;
- and
- at least one memory coupled to the at least one processing unit with instructions being stored thereon, the instructions, when executed by the at least one processing unit, performing actions including:
- simulating, using a first group of redundant arrays of independent disks (RAID), at least one input output generator, and one or more spare disks, a rebuilding process for a second group of redundant arrays of independent disks using a first group of redundant arrays of independent disks (RAID), at least one input output generator, and one or more spare disks;
- obtaining a first performance metric, of a plurality of performance metrics, of the simulated rebuilding process;
- identifying, based on the first performance metric, a factor associated with rebuilding performance of the second group of redundant arrays of independent disks;
- and
- re-simulating the rebuilding process for the second group of redundant arrays of independent disks by changing at least one of the following:
- a number of the input output generators, and a number of the one or more spare disks.
