Yes, several times, but so far only under 2.0.x kernels. All
boxes did fine so far. We did have some disk fails so we had
the reality tests. One server did run for several month with
only one disk (the IDE cable was found dangling :-)

You have to know what you want it for. If you are used to the
luxury menues of ICP RAID controllers where you can do all sorts
of fancy cluster building software RAID is pretty arcane, but if
all you need is a bit more redundancy for your valuable data it's
a cheap way to get it. It won't help you at all for uptime since
IDE normally isn't hot-pluggable.
