EDIT: Version 17.07 has now been released, see the post Dell EMC Server Update Utility SUU 17.07 released.
The latest version of Dell SUU has been released. The SUU is an application used to help patch Dell PowerEdge servers. It will compare currently installed drivers and firmware with those available on the DVD.
It can be downloaded here.
But to make sure it is compatible with your Dell PowerEdge server I recommend you go to their technical support website, enter your Servers TAG, and then look in the System Management section for the latest version for your server.
Please note that the latest version is available as three separate ISO images which need to be joined together, and then burned onto a Dual Layer DVD.
UPDATE: 7.1.1 is now available, see here.
