True indeed. Completely in sync with you on that. The reason we went for hardware RAID in that context: The server CPU in context was a firewall, running ipchains serving users on the LAN as well 2 servers on the DMZ. The firewall CPU would be continuously analyzing the network packets all the time and we wanted to offload the RAID software overhead from the Server CPU's. We had some SGI visual workstations on the LAN, all of them came default with the Adaptec RAID, but none of them had the hot swap bay. ;-) It's always a huge battle between Hardware RAID and Software RAID. At least in a few contexts with Linux, software RAID seems to be a better option than hardware RAID.
