It is no secret that I am fascinated most by the Apple hardware that I will most likely never use in real life. I speak, of course, about Xserves, Xserve RAIDs, XSan, and all of Apple's enterprise offerings.
Just because I won't ever use them doesn't mean I don't want to read about them, and if you are interested in using a Xserve RAID in a predominantly non-Apple environment you would be wise to bookmark AlienRAID.org (which gets the Scott McNulty award for 'Cleverest URL I've seen in a while').
