AMD CPU EVC Matrix (VMware Enhanced vMotion Compatibility)

Enhanced vMotion Compatibility (EVC) simplifies vMotion compatibility across CPU generations. EVC automatically configures server CPUs with AMD-V Extended Migration technologies to be compatible with older servers. I've created a table with a quick overview about EVC Modes with their appropriate CPU Series and Codenames used by AMD to denote their CPUs.

vSphere 5 Homelab – ESXi on HP Microserver Gen8

Hewlett Packard has updated its widely distributed Microserver Series to Gen8. This extremely affordable server which was initially made for SMB and home servers has become very popular in the virtualization scene. Due to its low price and power consumption you can find this system in many virtualization home labs. The Generation 8 Microserver (Gen8 or G8) comes with more power, upgraded ports and an integrated iLO.


The HP Microserver Gen8 is available in 2 versions - G1610T and G2020T. Both models are equipped with a 2 core CPU and can support up to 16GB of RAM. The system is shipped with 4 hard drive trays, which allows the installation of any SATA hard drive. It also has a CPU socket, so you can change the CPU.

vSphere 5 Homelab – ESXi on Intel NUC

When you want to build a VMware vSphere Lab at home, Intel might have a great system for you: The Intel NUC family - The Next Unit of Computing. The system was initially designed to be used as home theater or digital jukebox. Due to it's power it is also a fully adequate replacement for a desktop computer. The Intel NUC is big on performance and surprisingly small in size and power consumption and thus makes it a great candidate for a virtualization home lab.


The Intel NUC System is available as system board only and with a chassis. Currently there are 4 models available, beginning with an Intel Celeron processor and ending with a powerful Intel Core i5 vPro processor:

  • DC53427HYE Kit / D53427RKE Board: 3rd gen. Intel Core i5-3427U (up to 2x 2.80 GHz)
  • DC3217IYE Kit / DC33217GKE Board: Intel Core i3 3217-U (2x 1.8 GHz)
  • DC3217BY Kit / DC33217CK Board: Intel Core i3 3217-U (2x 1.8 GHz)
