It's very important in this case to specify which orbit the satellite is going to be in. If you're in LEO like the international space station you spend all day inside the Van Allen Belt protected from all those charged particles that the sun is pumping out. You're still lacking the atmosphere's protection from cosmic rays but that's not a huge dosage.

If you go out to MEO then suddenly you're outside that protective magnetic shield and you have to deal with charged particles smashing into you and you want a large mass of water or wax shielding if you don't have radiation tolerant electronics.

SSO, a low earth orbit whose plane is perpendicular to the direction of the sun so it gets constant sunlight, is harsher than normal LEO orbits because it passes over the poles where the protection from the Earth's magnetic field is weakest, but it's still a lot better than higher orbits. This is probably where you want a datacenter to get constant sunlight and as much protection as possible.
