If you're already in a datacenter, getting 208V AC from an existing AC infrastructure is a lot easier, cheaper, and sometimes more plausible than building a DC plant. If you have your own facility, it's a different story, but if you do colo, you probably have more customers expecting AC than DC, so you'll at least need to maintain both infrastructure. -- Kevin Stange Chief Technology Officer Steadfast Networks http://steadfast.net Phone: 312-602-2689 ext. 203 | Fax: 312-602-2688 | Cell: 312-320-5867
