A little late in passing this on, but a curious piece of trivia: Blizzard were auctioning off the server blades for older realms in World of Warcraft. Hot Hardware has a good article about one of the server blades. Its intriguing to learn the specification of the server that ran a whole realm in the game (its not clear how many blades were needed to run a realm or if its just one blade per realm, the article is vague on this):
- Hewlett-Packard p-Class server blade
- 6GB ram
- 64GB SCSI RAID controller
- Unknown disk space (drives were removed)
