Flashcache is a write-back block device cache for Linux. Using the Linux device mapper (DM) it provides an overlay mapper, to cache chunks of data on a high speed caching device like a solid-state drive for fast read access.

Flashcache supports FIFO and LRU cache sets, is configurable and error resistant. It comes with a DKMS kernel module and a corresponding user land for command and control. Alternatively it can be configured as write-through and write-around flash cache, which does not store any persitent data in the flash volume, hence purging the cache upon reboot.

This package provides the DKMS kernel module.

Warning: Flashcache is known not to work on the i686 (x86_32) architecture and possibly others.
