A typical 1U server consumes ~800 watts (this obviously varies a lot depending on number of disks, CPU etc.) A 30amp 110 circuit provides about 3000 watts; so conservatively that is enough for about 3-4 servers. And if you loaded up a 42U rack with 1U servers, cooling would be off-the charts. You can actually buy special racks with built in water cooling for those kinds of rack densities. -- John Lange http://www.johnlange.ca --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
