Recently I have built a new lab. I was doing lots of research and I was looking for something which is energy efficient and quite, so I can keep it powered on all the time and at the same time powerful enough to keep running 20-25 VMs, including full stack of vSphere, vRA, NSX-T and PKS.
I was looking for a CPU which is at least 8 Core and from Intel. I wanted also as much as possible memory. And this is what I ended up with:
Motherboard: Supermicro X11SPA-TF
Memory: 6 x 32GB Samsung ECC R 1.2V DDR4 2666
Power supply: Corsair RM550x
CPU Cooler: Noctua NH U14s DX 3647
USB Stick: 32GB Kingston (ESXi Installation)
