Abstract
A distributed storage system places data in a time-based manner. The distributed storage system comprises a plurality of storage nodes for storing user data, and each user in at least one user is assigned a storage node sub-set for storing user data thereof. The distributed storage system monitors and records user accesses on storage nodes. The distributed storage system calculates a time-based access pattern of a user and time-based access patterns of the storage nodes outside the storage node sub-set of the user in the distributed storage system according to recorded user accesses. The distributed storage system adjusts the storage node sub-set of the user according to the time-based access pattern of the user and the time-based access patterns of the storage nodes outside the storage node sub-set of the user in the distributed storage system.
