dell utility partition R620 poweredge

Hello,

we are installing some R620 dell servers with sles 11 autoyast.

After the OS installation some of the servers have a dell utility partition but others don't have it.

Device Boot      Start         End      Blocks   Id  System
/dev/sda1              63       80324       40131   de  Dell Utility
/dev/sda2           81920     4288511     2103296   82  Linux swap / Solaris
/dev/sda3   *     4288512   780140543   387926016   83  Linux

Device Boot      Start         End      Blocks   Id  System
/dev/sda1            2048     4208639     2103296   82  Linux swap / Solaris
/dev/sda2   *     4208640   780140543   387965952   83  Linux

Who is creating this partition? Why some servers have it and others doesn't?

Thanks and BR/
