for a somewhat larger client's installation we ordered a safe containing
rackmounts, ups and air conditioning. those boxes are quite expensive
(and quite big), heavy to lift (trust me, noone's ever gonna carry such
a thing out of the building) and they provide the physical security
level demanded by the german bank and insurance industry. hard drives
cannot be removed when the safe is closed, so you just got to think
about a good network/os security solution.

we put /, /usr, /opt (custom binaries) on a write-disabled scsi
harddisk raid mirror, the remaining filesystems went onto a standard
raid5 scsi-scsi bridge solution. software upgrades are being deployed
onto new disks on the same hardware in a lab and then transported to the
site for being actively deployed (swapped agains the original boot
volume disk set).
