Don't you have a mechanical engineer on the project responsible to size the data center cooling system?

But yes, you shouldn't have any latent load, so for your coil Total kW = Sensible kW.

Without seeing your idf file (maybe you should share it), I would definitely look at how you defined your internal loads from the server. You probably used an "ElectricEquipment" object, make sure your fraction latent is set to zero there.
