A word of caution regarding the 3ware cards -- this bug hasn't yet been solved:
- Extremely high iowait with 3Ware array and moderate disk activity https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121434
That is an annoying bug, but it's also an odd one. Not every system with 3ware cards hits the bug, and those that do hit it seem to do so to various extents. It's just... odd. Which, I gather, is what has made it so hard to track down.
