Summary:The embodiment of the invention discloses a distributed storage unit set and a related data storage method, and is characterized in that the distributed storage unit set stores data through erasure code EC strips, and each EC strip comprises m first data blocks and k second data blocks; the distributed storage unit set comprises a plurality of storage unit groups, each storage unit group comprises a main storage unit, the main storage unit in the target storage unit group receives a first request sent by a client, and the first request comprises n to-be-stored objects; judging the size relationship between n and m; when n is less than m, determining the n to-be-stored objects and the m-n blank objects as m first data blocks of the first EC strip; performing check coding on the m first data blocks to obtain k second data blocks; and storing the first EC strip into m + k storage units. By adopting the embodiment of the invention, the reading efficiency of the object data can be improved under the condition of e
