STORAGE MANAGEMENT METHOD, ELECTRONIC DEVICE AND COMPUTER READABLE MEDIUM
First Claim
1. In electronic equipment, a storage management method, comprising:
- receiving a request for a target storage block in a disk;
obtaining, from a cache, a cache indicator indicating a state of a group of storage blocks including the target storage block, the number of bits occupied by the cache indicator in the cache being less than the number of storage blocks in the group of storage blocks; and
responding to the request based on the cache indicator.

Abstract
Various techniques are directed to a storage management method, an electronic device and a computer readable medium. Such techniques may involve: receiving a request for a target storage block in a disk; obtaining, from a cache, a cache indicator indicating a state of a group of storage blocks including the target storage block, the number of bits occupied by the cache indicator in the cache being less than the number of storage blocks in the group of storage blocks; and responding to the request based on the cache indicator. Such techniques can reduce times of access to the disk and thereby enhancing input/output performance.
