Abstract
Aspects disclosed in the detailed description include hardware accelerated storage compression. In one aspect, prior to writing an uncompressed data block to the storage device, a hardware compression accelerator provided in a storage controller compresses the uncompressed data blocks individually into a compressed data block and allocates the compressed data block to a storage data block in the storage device. The hardware compression accelerator then generates a modified logical block address (LBA) to link the uncompressed data block to the compressed data blocks. In another aspect, the hardware compression accelerator locates a compressed data block based on a corresponding modified LBA and decompresses the compressed data block into an uncompressed data block. By performing hardware accelerated storage compression in the storage controller, it is possible to reduce processing overhead associated with traditional software-based compression systems and improve compression control over traditional storage device driven compression systems.
