You are better off with software raid unless you buy those systems with the
add-in 3ware card. Looking around the net, the only software raid solution
that I see that says it supports hot-swap and auto-reconstruction is EVMS
(evms.sourceforge.net). But RedHat (and CentOS) don't ship with EVMS.
I couldn't find anything to say whether the linux MD code does or doesn't
support hotswap.
