They don't even have to build the whole datacenter -48V DC. They could setup a PDU to power a particular row of racks or area. But they don't. Apparently because they would never sell it even if they had it. I, too, have been pondering 208v power. Electricity is my managed hosting operation's biggest single expense. I'm not sure how the datacenter's power distribution system works but they currently have to run me 4 20A per rack. Coudldn't they cut that approximately in half (power factor correction etc, as mentioned earlier) if I ran 208v? Seems like that would be cheaper for them. I haven't even talked to them about pricing but now I want to talk to them and see what their deal is. -- Tracy Reed http://tracyreed.org Digital signature attached for your safety.
