As the server uses hardware RAID we cannot simply swap the disks into a different box and replacing the PSU etc is likely to take about a week.

From experience in a datacentre, RAID mounts fail. Esp. DELL. RAID batteries fail. A lot of RAID hardware is proprietary and buggy. Software RAID is often worse. Rebuilding configurations with broken RAID setups can be really hard.
