If you are using RAID, I don't suggest having it on the motherboard. The reason for this is failure. Unless you have another m/b of the same type, it will be difficult to recover your data.
But you have backups anyway, right?
OK ,let's ask the awkward questions. 1.How many of the members of this list have *complete* backups the their umpteen-gigabyte disks? 2. How long would it take you to rebuild your system to ts *current* state after a disk crash?
I have complete, daily tape backups, but I have never yet managed to rebuild a system in under a week. The new system always has a slightly different configuration from the old one, and there is always something that I overlook when selecting what to restore. Then there are incompatible libraries etc.
We have a backup server, and we use rsync-diff to backup all the orther servers to it. The bu server is then itself backed up to another server in "another place". I think we're as well covered as we can be. Our Gentoo build is automated, requiring only a few questions asked and about 5 config files, so rebuilding a server takes 3 hrs, then the data restore. All data is stored in a separate partition, making restoration easier.
