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 …
