ESXi Server auf ASUS KCMA-D8

This is more or less only a “rough” GOOGLE translation. If You have any questions, drop me an email.

After my “old” ESXi server has served me well, it went downstairs into my basement (my computercenter, so to say. I had tried to get a little bit more memory to use by getting an extra graphics with own memory and VGA output instead of the digital output. For any purpose, I wanted to have a analog TFT screen in the cellar, but just an old analog TFT. Well, at least I probably left the TFT on the machine, sitting on the ventilation and something got to hot. So there had to be some (partial) renovation to come. I did a lot of research to find out what solution would make the most sense for my (private) purposes. At the end this was my plan:

Mainboard: ASUS KCMA-D8

Mainboard ASUS KCMA-D8

The board can carry 2 Opteron-Prozessoren (4 or 6 core) in the new C32-socket.

and up to 128GB RDIMM RAM or 32GB DIMM. 6 core per processor is the maximum configuration for the free ESXi licence. The processors like to be well cooled, so I got for  NOCTUA NH-U9DO A3 CPU-cooling for C32- and C34-sockets. Here the NOCTUA:








And here mounted with processor but no fan:

And here both processors:

Network (2) and SATA-controller (6) looked good for the ESXi. It is a server board, so graphic capabilities isonly what You realy need (8MB extra VRAM). Just what You need for ESXi.



To keep it short.


But let’s see. I did not buy RAM from the compatibility list, just plain ADATA 4GB 1333 Premier. Just a few for testing …

… testing with ESXi as well …

… and because everything looked fine .. filling the RAM up. The BIOS checks for the RAM and said “compatible”. And even the installation of the ESXi from CD to an USB stick … no problems.

No problems during the installation

Oh yes, the usb stick. Ingenious USB stick detail: There is a USB port sitting directly on the mainbord. Labeled as USB7 you just plug a stick into it. So it is never in the way and you can boot directly from that stick. And you still can plug in a USB-CD to boot from there or install ESXi.

USB7 - auf dem Mainbord.
Geniales Detail: Der USB-Port 7 sitzt auf dem mainboard.


There is also a small daughterboard available from ASUS. The management Board is only 50 Euro but does a lot: You can monitot everything a “remote control” the machine:

Management Board ASMB4-iKVM
Noch ein geniales Detail: Das Management-Board enabled LAN3

This board enables (after a BIOS upgrade) LAN3. There is a small webserver for monitoring running, even in standby, where you can see everything what is needed.

You can define tresholds to send an email at alert or giving an SNMP trap.

  • Shaik:

    Hi, I just bougth the same mother board as your but struggling to find a compatible raid controller that will be supported by ESXi5. The board supported PIKE 1078 is discontinued and no longer available in the market. Can you please guide me with what controller you used for SATA II disks.


  • mejohnm:

    Cool build. Do you know how many watts it takes per hour?

    • Regarding power.
      I am currently running with 4 HD (Hitachi 2 TB in a Raid 5) one 3TB HD an one 1.5TB HD and 32GB RAM. Half of the ressources are assigned. Power consumption is 150 … 200 Watts debending on what the vms are doing.


      • mejohnm:

        Thanks for the reply. Your power consumption looks pretty good. I am going to go with this board for my next build using HE Opterons. I hope to see power consumption around 100 to 150 watts. At idle I hope less.

  • Aha, hatte grad die selbe Idee und auch einen Blick auf dieses Mainboard geworfen.
    vSphere 5.1 free hat jetzt keine Core-Limitationen mehr. Also könnte ich auch einen Valencia mit 8 Cores pro Socket verwenden.
    Der USB-Anschluss gefällt mir auch, so könnte ich den Host diskless betreiben.
    WAs mich ein wenig wundert ist die Höhe der Kühler und Lüfter. Kriegt man da noch einen Deckel drauf 😉 ? Was für ein Gehäuse hast Du gewählt?
