Abstract:
Disclosed is a storage system comprising: receiving a first data segment and first metadata associated with the first data segment to be stored in the storage system; storing the first data segment and the first metadata in a persistent storage device of the storage system; compressing the first data segment using a predetermined compression algorithm to generate a first compressed data segment; and storing the first metadata and the first compressed data segment in a solid state drive (SSD) cache device of the storage system, including aligning the first metadata and the first compressed data segment to a page boundary of the SSD device to reduce a number of input and output (IO) operations required for accessing the first metadata and the first compressed data segment from the SSD cache device.
