Abstract
Metadata in volatile memory is selectively compressed and destaged to non-volatile storage in the event of an emergency shutdown due to loss of like power. Compression offload hardware that is normally used for data compression is used to compress the metadata, e.g. at line speed. The compressed metadata and any uncompressed metadata that was not selected for compression may be destaged to vault drives along with compressed and uncompressed data that is in the volatile memory. Compression during vaulting may decrease power consumption when operating under standby battery power.
