Unisys is still around, but yes this is a white label server and could have been used for running a specific image/solution. What OS does it boot up to?
I would try to update the BIOs and see if that updates to a Dell version, but it might not be required to reinstall whatever you want.
Thanks, No OS Yet but will be a 2nd XCP-ng server. I wanted to update all the hardware and setup network, ETC first and that’s when I got the big Surprise That way it looks just like my other Dell R720 LFF.
