I am using Sandisk Readycache on my raid 10 and 5 at home built computer.
For work I using LSI Cachecade 2.0. I was hoping to use Fancycache with L1 and L2 combination. Fancycache had the highest performing mark of any caching software that I had test so far. It can not be put into production line yet til it goes out of beta. I was waiting on the persistent caching feature b/c my servers get reboot every two weeks to clear out any dirty memory. But waiting 4 hours for the hot data to get cache again are ridicules.
As some users are interested in the new version, here is a beta version can be downloaded for preview. It is a total new program and not based on the previous version of FancyCache. Also, the product name is changed to PrimoCache. Most features are implemented in this version, though some features are not enabled in this version. As this is a preview version, we highly recommend that you test it on a non-production machine and make a backup of system before testing.
It seem once the L2 cache have enough OS data, the boot up data is mostly read from the SSD. The cache rate hit can reach up past 95%. The hard drive barely have any activity. Please see screenshot. I had repeat the process 3 times. Very impress indeed.
