If you go propane/NG upsize quite a bit to have smooth power. Diesel's torque makes for smoother power output undering changing loads. Diesel can run full rated load of datacenter load.
I went diesel (Cummins/Onan) for my datacenter. I put the generator inside to prevent winter fuel gelling, rodents, rust, etc... It's on a 275 gallon heating oil tank. Looks almost like new still after 10 years. There's a whole set of design requirements for having a generator inside, in terms of fire safety, fresh air flow for combusition and cooling, etc..., that's why most are outside. I was building from scratch, so I put it where I wanted it. Had a boatbuilder put a custom stainless steel exhaust on it coming out the side of the building. Get something that matches the voltage and phase your utility provides. Don't get a 1 phase for your 3phase service. Get an appropriate high quality auto transfter switch that can switch your whole datacenter over, not just select circuits. The transfer switch should also be able to exercize the generator on a schedule. Check the hour meter and fluids once in a while so you know it's exercizing properly and ready for use.
