Just to add my 0.02c worth to the discussion.... I don't like a lot of hardware raid because they don't provide a consistent interface to the raid status. With software raid, every machine regardless of linux (kernel) version, distro, or libraries, they all have identical status information in /proc/mdstat. Personally, I use hobbit (1) to monitor all my servers, and have a small script which polls /proc/mdstat every 5 mins to check that everything is working nicely. This has been in use for many years (well before mdadm days) and still functions quite nicely. I've recently used a couple of the 3ware sata raid controllers, and they didn't seem too painful once you get over the learning curve of installing the web interface/etc... BTW, there is a command line interface as well, which I managed to modify my above script to cater to as well. Not all machines live near a person who will ask "Why is there an alarm going off?". Currently, the difference between HW and SW RAID is basically a cost consideration... but if the customer has the budget, I would suggest the 3ware controllers are a good option.
