Most decent nodes will have IPMI and kvm over IP built in. That and a
reasonable serial concentrator will make your admins lives *much* easier.
We help manage clusters/storage hundreds, thousands, and often
continents away from us. A crash cart makes it infeasible to consider
this. And if the admin gets paged by someone at 3am, I am sure they
won't want to drive in and use the crash cart to find/fix the problem.
Keep the crash cart, but don't spend more than $300 on it (monitor +
keyboard/mouse and a cart that rolls). It isn't for management, its for
