LambSpam asks: "I had a nightmare week (last week) with two of our servers running Intel's U3-1L RAID controller (RAID 5). Whenever there's a power outage in our building these controllers randomly mark one or more of the drives in the array offline (even with adequate UPS support), which means I have to manually mark them online and/or rebuild. Intel acknowledged the problem, but their solution involves updating the backplane's firmware, the controller firmware (destructive upgrade!), and even the firmware on our IBM drives in the array because they 'draw too much power' in certain conditions. I've only used one other RAID 5 implementation (MegaRAID), and it NEVER had these kinds of problems, whereas if you sneeze too hard around this U3-1L card it will go offline. Is this common with most hardware RAID implementations? What RAID 5 implementations works without hassle? What should I stay away from?"
