So I'm looking at upgrading a few 8020s and trying to choose between flashpool and flashcache. Flashpool is more expensive, even with just 12x200 SSD drives, and we'd need to find space in a very tight rack for it. The workload is 80% exchange and 20% VMWare, and we would like to use deduplication without snapshots.
Is it possible to use PCS to compare flashcache and flashpool benefits? How can I translate the data I see from a stats show -p flexscale-access into real numbers, like reduction of latency?
