Right.  You can't put a cache on XFS.

I don't particularly recommend memcache.  It seems to have odd issues, and
it isn't that widely used.  It would be nice for someone to take the time
to hammer on it and fix the issues, but until then, it's better to find a
way to use a disk cache.  (On Unix at least; I can't speak to Windows.)

Yup, should work fine.
