Abstract
A storage processor in a data storage system includes a compression selection component that selects a data compression component to be used to compress host I/O data that is flushed from a persistent cache of the storage processor based on a current fullness level of the persistent cache. The compression selection component selects compression components implementing compression algorithms having relatively lower compression ratios for relatively higher current fullness levels of the persistent cache, and selects compression components implementing compression algorithms having relatively higher compression ratios for relatively lower current fullness levels of the persistent cache.
