Apple likes to think they are at the cutting edge of the tech industry and they are in many ways. One way in which Apple falls short is in extended warranty support for the Xserve. The Xserve is Apples 1U rack-able server. They make an accompanying product called the Xserve RAID. The Xserve RAID is a box of disks. My company has an Xserve and the RAID box. It is going out of warranty and Apple does not sell an extended warranty plan. Our only option is per incident support, and/or to purchase spare parts and keep them on hand. Other than that, we are on our own.
Servers these days are capable of running for more than 3 years without replacement. There is nothing wrong with our box. Apple wants to break into the server room, but they don’t provide the support to do it.
The second thing that Apple is missing is the ability to run OS X virtually, but that’s a whole other story.
