Per ASHRAE 90.1-2013 & 90.1-2016 Appendix G3.1.1.g:
"Computer rooms in buildings with a total computer room peak cooling load >3,000,000 Btu/h or a total computer room peak cooling load >600,000 Btu/h where the baseline HVAC system type is 7 or 8 shall use System 11. All other computer rooms shall use System 3 or 4."
So System 3 PSZ-AC or System 4 PSZ-HP is probably the correct answer for your application, unless you've got a really big server room.
