Seems fine to me, you used your power in two racks, to get
more power
will cost the provider more so you will have to pay more.
This is just
an extreme example of blade servers causing half a rack to
be empty
the facts haven't changed no matter how bad seeing empty
racks feels

Waste implies you could use it for no additional cost, old
pricing
models were vulnerable to gaming on combinations they'd not
thought
through.

It might be easier for people to understand in these cases
if the provider put yellow/black stripe tape over the
unused
space with a big sign saying "not yours"

That's nice, I hate cages where you have no room for tools
or to work
and the kit hits the walls when you try and unrack it. I've
no
idea how they fit a normal engineer in some

Accepted, big fan on the back of the rack? Plenty of empty
space for such solutions.

High density servers seem to be vendor driven, they can
charge more and make you buy the switch and other
ancillaries
you'd likely choose cheaper from others. And when new models
come
out the whole lot gets replaced rather than just the odd few
U
of servers. The convenience may be worth the high price for
some
situations

Density is just another DC design parameter to be optimised
for
profit
