Abstract: Systems and methods are provided for an erasure coding object storage system. One method may comprise receiving an object for storing in an erasure coding object storage system, partitioning the object into a plurality of chunks including a first chunk and a second chunk. The first chunk may have a first chunk size and fall into a first bucket, the second chunk may have a second chunk size equal to the first chunk size multiplied by a ratio q that is larger than one and fall into a second bucket. The method may further comprise encoding the first bucket using a regenerating code with the first chunk size, encoding the second bucket using the regenerating code with the second chunk size and storing the encoded first and second buckets in a plurality of nodes of the erasure coding object storage system.
