blade servers (1955)

[Erik Cummings]

One other note - at least in my area - there is only ONE Data Center around that actually charges power by meter (usage) instead of circuit size.  So, if you intend to have these in a data center, the dual 220v 30a circuits (for full redundancy) can cost WAAAY too much.

Now, for any non-110v / N. American parts of the world, this is probably a complete NON-ISSUE!  Ugh...the fools who went w/ 110...
