Abstract
Data compression and decompression methods for compressing and decompressing data based on an actual or expected throughput (bandwidth) of a system. In one embodiment, multiple access profiles are utilized to assist in compressing data according to various compression rates and compression ratios.
Claims18
A method comprising:
- receiving a data block;
- determining a data type associated with the received data block;
- selecting an access profile from a plurality of access profiles based, at least in part, on a number of times in which the determined data type is written to a storage device relative to a number of times that the determined data type is read from the storage device;
- retrieving information from the selected access profile, wherein said information comprises a compression parameter;
- and
- compressing said data block, to provide a compressed data block, based, at least in part, on said compression parameter.

A system comprising:
- a data storage accelerator, wherein the data storage accelerator is configured to:
- receive a data block;
- determine a data type associated with the received data block;
- select an access profile from a plurality of access profiles based, at least in part, on a number of times that the determined data type is written to a storage device relative to a number of times that the determined data type is read from the storage device;
- retrieve information from the selected access profile, wherein said information comprises a compression parameter;
- and
- compress said data block, to provide a compressed data block, based, at least in part, on said compression parameter.
