This run is very similar what I had on Intel SSD X25-M card, but now I use FusionIO 80GB SLC card. I chose this card as smallest available card (and therefore cheapest. On Dell.com you can see it for about $3K). There is also FusionIO IO-Xtreme 80GB card, which is however MLC based […]Read more
Finally I was able to run PBXT 1.0.11 pre-GA in tpcc-like workload, apparently there was bug with did not allow me to get the result earlier, and I am happy to see that PBXT team managed it.
For initial runs I took tpcc 100 warehouses ( about 10GB of data) which fully fits into memory […]
Previously I covered simple case with FlashCache, when data fits into cache partitions, now I am trying to test when data is bigger than cache.
But before test setup let me address some concern (which I also had). Intel X25-M has a write cache which is not battery backuped, so there is suspect you may […]
I wrote about FlashCache there, and since that I run couple benchmarks, to see what performance benefits we can expect.
For initial tries I took sysbench oltp tests ( read-only and read-write) and case when data fully fits into L2 cache.
I made binaries for FlashCache for CentOS 5.4, kernel 2.6.18-164.15, you can download it from […]
