According to http://arstechnica.com/information-technology/2013/04/linux-3-9-brings-ssd-caching-and-drivers-to-support-modern-pcs/ linux have built in capability to allow using SSD to cache hard drive.
How to do so?
Where is the tutorial?
This feature is already in the standard kernel right? WOuld it work on centosh?
Can I just upgrade existing kernel?
