Engineering Everquest

The IEEE Spectrum site has an article up discussing the engineering required to keep Norrath running. From the article: "The Death Star is a huge, warm, windowless room containing the rows and rows of servers that run Sony's online games. The whooshing of a massive air-conditioning system is so loud that conversation is almost impossible. A large steel cage surrounds more than 500 servers stacked 32 high in towering racks--and this is just one battalion, albeit the largest, in Sony's 1500-machine army of servers."
