On a much smaller system (3 drives, 1 3ware card), I had power problems. I used a 400W power supply and the +-5V rail was only delivering 3.9V. I kept losing drives. This was an 'expensive' Antec power supply.
I switched to a budget 300W power supply just to see what would happen. The unit delivered a much cleaner ~4.8V. It's worked great ever since.

This of course leads to a several hour downtime as the system has to be powered down (not just rebooted) and then the volume needs to be fscked. I've been back and forth with both the vendor and (via the vendor) 3ware with this. The card has been replaced, as well as the whole system. I'm running the latest firmware and drivers from 3ware.
That looks like either drive, cabling, or power problems.
I'd agree, except for a) all the hardware has been swapped out and b) 1500W should be plenty.
It's starting to sound like this may be a somewhat known issue with a *long* overdue fix coming from 3ware. *sigh*
Thanks all.
