Most likely if you are running a lab based on either Intel NUC or Apple Mac mini you are suffering from scarce RAM resources. Even more so, when you have a VSAN enabled consuming approximately a third from your total RAM per ESXi host (at least in my case). So, I day-dreamt thinking wouldn’t 16GB RAM modules be great?
Hence, I found myself browsing for 16GB SO-DIMM modules, and I have found them here:
Though, there are some caveats with these modules:
- They don’t come cheap (it essentially doubles the cost of a NUC easily)
- They’re only working on Intel’s Haswell generation (they won’t run on any of the Mac mini systems)
I told myself to give it a try with a single system, and in short: it works perfectly!
I ordered an Intel NUC5I5RYH, an HDD and a SSD M.2 device, and two pieces of Intelligent Memory 16GB SO-DIMM (IMM2G64D3(L)SOD8A) modules. In the end to make it really happen and working my thanks goes to the following bloggers and their respective posts, I strongly advise you to read:
- Florian Grehn from virten.net on his posts about Intel NUC, in particular How To Fix ESXi On Intel NUC Malformed Manufacturer And Model, and ESXi 6.0 Image For Intel NUC
- v-front.de for their excellent vibs-depot in particular SATA-XHCI (I installed the vib-file directly from their repository – instructions)
- Gordon Mah Ung for his report on Intel NUC running 32GB of RAM on Windows
