For a router/switch data points (this is NANOG, after all): http://www.cisco.com/en/US/prod/collateral/routers/ps5763/prod_brochure0900aecd800f8118.pdf The CRS-1 in 16 slot or fabric chassis configuration takes a full rack and needs ~11,000W. 6509-E's take dual 6000W power supplies. They are 15U, and I have seen 3 of them stacked in a 48U cabinet (obviously doesn't work in a 42U rack). That's 18,000W draw in a single cabinet. I'm afraid 6000W is on the low end, by today's standards, and some of the new 1RU multi-system chassis or blade servers can make these numbers look puny. For instance: http://www.themis.com/prod/hardware/res-12dcx.htm Dual quad-core Xeons in a 1RU form factor. 600W power supply. 600W * 42 = 25,200. What do you expect your customers to bring? How long do you expect your data center to last? Not that long ago people were building 5000W/rack data centers; often those places today have large empty spaces, but are at their power and/or cooling limits. -- Leo Bicknell - [email protected] - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Attachment:
