How big of a challenge are hardware faults and radiation for orbital data centers? It seems like you’d eat a lot of capacity if you need 4x redundancy for everything

Orbital datacenters is a hypothetical infinite money glitch that could exist between the times:
- after general solution to extra-terrestrial manufacturing bootstrap problem is found, and, - before the economy patches the exploit that a scalable commodity with near-zero cost and non-zero values can exist.
It'll also destroy commercial launch market, because anything of size you want can be made in space, leaving only tiny settler transports and government sovreign launches to be viable, so not sure why commercial space people find it to be a commercially lucrative thing? The time frame within this IMG can exist can also be zero or negative.
The assumption is also like, they'll find a way to rent out some rocks for cash, so anyone with access to rocks will be doing as it becomes viable, and so, I'm not even sure if "space" part of space datacenters even matter. Earth is kinda space too in this context.
Orbital data centers are still nothing more than the current hyperloop.
They dont go into here.. but I thought that NASA also used like 250nm chips in space for radiation resistance. Are there even any radiation resistance GPUs out there?
Absolutely not, although the latest fabs with rad-tolerant processors are at ~20 nm. There are FDSOI processes in that generation that I assume can be made radiation-tolerant.
NOPE, RAD hardened space parts basically froze on mid 2000s tech: https://www.baesystems.com/en-us/product/radiation-hardened-...
It seems not; anti-interference primarily relies on using older manufacturing processes, including for military equipment, and then applying an anti-interference casing or hardware redundancy correction similar to ECC.

Orbital data centres are a stupid concept.
You don't need 4x redundancy for everything. If no humans are aboard, you have 2x redundancy and immediately reboot if there is a disagreement.
