    摘要: Techniques for performing de-duplication for data blocks in a computer storage environment. At least one chunking/hashing unit receives input data from a source and processes it to output data blocks and content addresses for them. In one aspect, the chunking/hashing unit outputs all blocks without checking to see whether any is a duplicate of a block previously stored on the storage environment. In another aspect, each data block is processed by one of a plurality of distributed object addressable storage (OAS) devices that each is selected to process data blocks having content addresses with a particular range. The OAS devices determine whether each received data block is a duplicate of another previously stored on the computer storage environment, and when it is not, stores the data block.
