So there results for FlashCache with 20% and 80% of dirty pages and FlashCache based on Intel X25-M: So… be interesting to see how it works when we put FlashCache on FusionIO cards instead of Intel SSD.

And this is interesting problem with FlashCache what I see. Warmup by simple… next rounds I am looking to run similar benchmarks on FusionIO card. P.S. And if CentOS team reads this post…

… fair to get comparison with FusionIO card, especially for write pressure case As you may know FusionIO recommends to have space reservation to get sustainable write performance (Tuning Techniques for Writes). I took FusionIO ioDrive 160GB… impressive, and it can be quite important in workloads like FlashCache, where card have both concurrent read and write pressure Quite…

…, maybe FlashCache will not work as expected in any case. For FusionIO you may look into their DirectCache cache instead of FlashCache. Virident tachIOn cards (only SLC now) shows acceptable performance with full disk, so they may work better with FlashCache.

I forgot to mention on the topic that I’m *extremely* excited to test FlashCache soon. We have several DB’s that are too large to fit on an affordable amount of FusionIO storage, but that probably have *working* sets that would fit in the FusionIO card in a cached manner. *drools*
