Re: Very clever stuff
It's not matter of worrying about it, it's about making further economies. Whilst it's true that a system might need to be resilient to one of its servers going away, there's almost always an incentive to keep as many of them up and running as possible. If you size the system to provide the required level of service despite a worst case rate of equipment failure, power cuts, patching reboots, upgrades, etc, then eliminating patching reboots means you need less hardware.
