So at work the servers seem to have the standard power cord, but they also have another power source which is connected to a rectifier that has an earth, live and neutral wires coming off of it.. I'm a bit confused about the latter.. How are these two power sources different???

Are you sure they haven't got one power supply on the mains and another through a UPS? Ideally you'd have both PSUs on different UPS's but that's not always feasible.

Is it true that business and warehouses etc get AC power so the rectifier is used to convert that into DC?
