Abstract
A hardware accelerator device detects duplicate data blocks independently from a processor of an information handling system. The device includes an interface, a hash function, a bloom filter, and a data comparator. The interface receives data blocks. The hash function determines a hash of a received data block. The bloom filter includes comparison hashes, each associated with a comparison data block. The bloom filter determines if the hash matches a comparison hash. The data comparator directs the interface to receive the comparison block when the hash matches the comparison hash, and compares the received data block with the comparison data block to determine if they are identical. The device stores a pointer when the data comparison block determines that the blocks are identical.
