Improving Percona Server performance with Flashcache on the Virident tachIOn Drive

You are here

Using flash storage as a second-level cache for MySQL, between disk and main memory, reduces I/O latency while avoiding the size and cost limitations of storing the data on flash alone. This white paper presents the results of our benchmarks with Facebook's Flashcache module and the Virident tachIOn PCI-E storage device. We explain when it is cost-effective to use Flashcache, we show the performance characteristics of the hybrid storage, and we develop guidelines for selecting and deploying the components.
