We are looking at a few colo data centers and one is running 30a 120v to the cabinet and another is 30a 220v. The latter is telling the 220v is better for servers, SANs, etc. I've never heard of this. My data center has 220 but we kick it down to 110 for delivery to the equipment via various UPS'.
My questions are:
Is there some reason(s) 220 is better then 120 for servers and other equipment?
Are there any other reasons to pick 220 over 120?
There's a significant price difference per month and this is not an area I feel I'm that versed in. Any and all advice is a appreciated.
