Abstract
Compressing data of a storage device includes selecting a portion of data for data compression that is predicted to be unlikely to be accessed, selecting a particular one of a plurality of data compression algorithms to apply to the portion according to a frequency value associated with each of the data compression algorithms, and adjusting the frequency value of the particular one of a plurality of data compression algorithms according to performance of the particular one of a plurality of data compression algorithms. The performance may vary according to a ratio of amount of compression achieved to processing cycles of a processor used to compress the portion of data. The processor may perform storage device functions that are separate from data compression. The portion of data may be selected from a plurality of logical devices used in connection with a single application that accesses the storage device.
