Dell has introduced the AMD Epyc server processor to Dell PowerEdge servers – What to know when installing and using operating systems on the R6415, R7415, and R7425 servers.
Dell PowerEdge servers have traditionally used Intel processors, but the new AMD Epyc processor is now an option on the server models listed above, and there are some specific nuances you should to be aware of when installing/using some operating systems.

For VMWare, be sure you update to the latest release:
* Navigate to the Platform’s support page and under Drivers, change OS to ESXi 6.5 and then in the Enterprise Solutions category, download the latest image.
For RHEL7.4, there is a bug that will prevent system boot up due to a kernel panic. The fix for the kernel panic is in this errata kernel:
