Hello, I am new here, but I have a problem I need solutions, I recently bought 4 of these Server supply units for my battery project and want to connect two together but can’t find the DC ground to isolate one of them, please can anybody help me out, thanks.

Unfortunately without detailed schematics, there is no way of knowing how to isolate that dc ground. And, this psu may not need the ground isolated. I just don't know since I have never worked with this power supply. And to be honest, when we are talking about floating a ground, unless I have talked to someone that REALLY knows what they are doing (as such is the case with the HP psu's that I did a video on), I will never suggest floating a ground on anything. It can kill you if done wrong.

Hello Tony, please i know what am doing I am electrical technician by profession and have 23 years of working experience and of-cause I can’t know all as each day new technology and Gadget come to play.

And Tony can't know how each and every power supply is constructed either. The PSU's that Tony's worked with, had the available info already on the internet... pictures of the outside of a box just doesn't cut it.
