Most datacenters have a hardware stock you can purchase if something dies. The most common failures are fans and hard drives. If your motherboard dies, you would need to have one drop shipped in and just pay for remote hands to install it.
With hard drives, most RAID controllers support running a hot spare. So you can have a hot spare incase a drive dies giving you the ability to suffer two drive failures in a RAID5 configuration.
