Dell Repository Manager Data Center Version 2.1 User’s Guide

DUPs are update packages from Dell, which help you to keep your system up to date. DUPs are application and are available in a variety of formats; Windows 32 bit, Windows 64 bit and Linux (32 bit and 64 bit). In case you are not sure about the type of DUP that you should run in to the system, select 32 bit DUPs, since the 32 bit DUP can be applied even for 64 bit operating systems. If you are using a Windows Server OS that does not support WoW64 (Windows 32-bit on Windows 64-bit) then you must select 64 bit DUPs.
