Abstract
Techniques for data storage involve selecting a target Redundant Array of Independent Disks (RAID) from a plurality of RAIDs in a storage resource pool. Such techniques further involve determining a local neighbor matrix of the target RAID based on the target RAID, wherein the local neighbor matrix indicates distribution of a plurality of storage extents of a plurality of RAID extents of the target RAID on the storage resource pool. Such techniques further involve performing a resource reallocating operation on the storage resource pool based on the local neighbor matrix. Accordingly, a local neighbor matrix can be calculated at the granularity of an individual RAID, and the local neighbor matrix can be applied to balance a local neighboring relationship, so as to ensure overall balance of the neighbor matrix of the entire storage resource pool and improve IO performance.
