That makes sense, network gear doesn't suck a lot of power. For compute though, I always have to have the conversation with clients that multiple hours of UPS backup for a server rack is crazy expensive. They are usually better off with a UPS that can take over while a generator spins up if they really need that kind of reliability. I always ask, what are the odds that your 8 hour power outage scenario isn't from something catastrophic like a flood or a fire, eg, if the power is out for that long, something is probably literally on fire and you've got bigger problems.
