  • Patent number: 10579586
    Abstract: A method of managing objects in an archive system includes assigning a number of addresses to each of a plurality of nodes, dividing an object into a sequence of blocks, uniformly distributing the sequence of blocks across the plurality of nodes by, calculating a hash value of a unique identifier of the object to be used as an address for a first block in the sequence, storing the first block at a node to which the address is assigned, for each subsequent block in the sequence, calculating a subsequent address from a hash value of the address of an immediately previous block in the sequence and storing the subsequent block at a node to which the calculated subsequent address is assigned, iteratively calculating a hash value of the hash value of the subsequent address if the calculated subsequent address is assigned to a node where a previous block is stored, and storing the subsequent block at a node to which an address corresponding to the iteratively calculated hash value is assigned.
