Comment on An in-space construction firm says it can help build massive data centers in orbit

Include spares.
I hope they're reading this thread and taking notes, they probably didn't think of that.

and the infrastructure and robotics to replace them, of course.
Assuming 200 nvidia H100 failures a day (conservativo, reality is worse) that’s an extra ~340kg of weight you’d need to launch per day. Which is an extra 120 tons yearly.

So, one Starship launch per year. Doesn't sound like a problem.

at least two, you can’t stuff a rocket full of just gpus, you need something to actually dock and deliver the payload in space. So you need to launch at least 2 rockets (in a non-reusable configuration, so you need to pay for the whole rocket and the launch) to ship a bunch of gpus that are, at best, only 10% as fast as usual.
