METHODS AND APPARATUS TO ASSIGN INDICES AND RELOCATE OBJECT FRAGMENTS IN DISTRIBUTED STORAGE SYSTEMS

摘要

Methods and apparatus to dynamically assign and relocate object fragments in distributed storage systems are disclosed. In some examples, the methods and apparatus encode an object with error correction coding to separate the object into fragments, create a first index indicative of storage nodes where the fragments of the object are to be stored, encode a second index into identifiers of the fragments of the object, the second index based on the first index, and store the fragments of the object and the corresponding second index encoded identifiers in the storage nodes based on the first index.
