METHOD, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT FOR MANAGING REDUNDANT ARRAYS OF INDEPENDENT DISKS
First Claim
1. A method of managing a redundant array of independent disks (RAID), comprising:
- obtaining information on a wear level associated with each of a plurality of disks;
selecting, based on the information on the wear level, a group of disks from the plurality of disks, a difference between wear levels of any two of the group of disks being below a predetermined threshold; and
creating a RAID with extents from the selected group of disks.

Abstract
Techniques manage a redundant array of independent disks. Such techniques involve: obtaining information on a wear level associated with each of a plurality of disks; selecting, based on the information on the wear level, a group of disks from the plurality of disks, a difference between the wear levels of any two of the group of disks being below a predetermined threshold; and creating a RAID with extents from the selected group of disks. Such techniques can sufficiently utilize the wear level to balance the data storage distribution among redundant arrays of independent disks, thereby enabling efficient management of redundant arrays of independent disks.
