Abstract
A storage infrastructure, device and associated method for storing compressed data is provided. Included is a method for compressing data on a storage device in a storage infrastructure, including: receiving a compressed extent from a host, wherein the compressed extent includes data compressed with entropy-coding-less data compression; receiving logical identification information about the compressed extent from the host; performing in-memory entropy encoding on the compressed extent to generate a compressed unit; storing the compressed unit in a physical memory; and in a case where the host is aware of the in-memory entropy encoding, reporting size information of the compressed unit back the host.
