Ceph and EnhanceIO cache

[Dominik Zalewski <dzalewski@xxxxxxxxxxxxx>]

Hi,

I came across this blog post mentioning using EnhanceIO (fork of flashcache) as cache for OSDs.

http://www.sebastien-han.fr/blog/2014/10/06/ceph-and-enhanceio/

https://github.com/stec-inc/EnhanceIO

I'm planning to test it with 5x 1TB HGST Travelstar 7k1000 2.5inch OSDs and using 256GB Transcend SSD as enhanceio cache.

I'm wondering if anyone is using EnhanceIO or others like bcache, dm-cache with Ceph in production and what is your experience/results.

Thanks

Dominik
