The power profile of the SM10000 packs 512 Atom CPUs into a 10U server, capable of fitting up to 2,048 CPUs into a single seven foot, 40U rack. Each of its servers use less than 2 kilowatts of power, suggesting that a rack filled with SeaMicro servers can have a power load of under eight kilowatts – a manageable power load for most data centers optimized for high-density computing.
