The latest version of Dell Server Update Utility (Dell SUU) 16.10.00 was released on the October 2016. The Dell SUU is an application used to help patch Dell PowerEdge servers. It will compare currently installed drivers and firmware with those available on the mounted iso file.
Dell now have a product support page for the Server Update Utility which can be found on the link below.
The Dell Server Update Utility SUU 16.10.00 release can be downloaded below in 32bit format or 64bit format.
Note in this release Windows 2016 is now supported and the PowerEdge Server R830.
To make sure you use the correct SUU that is compatible with your Dell PowerEdge server I recommend you go to their technical support website, enter your Server’s TAG, and then look in the System Management section for the latest version for your server.
