=========================================================
We could continue deploying the majority of your storage from SATA
disks while also employing SSDs to cache these slower disks in
some manner.
The idea is that frequently-accessed data is backed on SSD whereas
data that is accessed less often is left on the larger-capacity
SATA, and *this remains transparent to the end user*, i.e. the VM.
This is not a new idea; plenty of storage hardware already does
it, ZFS can do it and so can BTRFS.

I like this option best. It means I don't have to worry about increased
IO on my VM.
What solutions have you looked at? Is bcache stable enough for use yet?
