IIRC nothing in the VAX cpu actually requires 3 phase. The PDU(s) just eat that from the wall.
I think that's the same with all the /computer/ equipment that I've seen which connects to 3ɸ power. A single phase could be used for all of it. But I'm told that it's simpler / more economical (from a wiring / cable plant point of view) to deliver more power to the equipment as 3ɸ than it is 1ɸ.
