Proxmox Lab: Intel NUC

Thanks for reading this first post in a new series I am putting together titled “Proxmox Lab”. In this blog series I will be covering various things related to Proxmox and the various hardware I have tested things on.

In this installment we will discuss a small foot print low power build that you can carry in your pocket, well, if you wear cargo shorts with the big pockets on the side.

Around two years ago I had purchased one of the earlier all black Intel NUC systems and a 32GB Crucial mSATA disk to run Proxmox 3.1 or 3.2, I forget the version at the time. Anyhow, around the same time that I attempted to complete the build of the device a client called up and expressed an immediate need for a small PC that could hide behind a conference room wall mount TV. Just like that my Intel NUC disappeared…

Months later I was able to find enough free time to get a new NUC, this time it was the more modern, current as of the time of this post, silver and black version. I went with the Core i3 variant as I didn’t want to go Celeron and the i5 was out of stock. Armed with 8GB of low voltage RAM (1.35V s required), I installed Proxmox to a 32GB Crucial mSATA drive and off I went. I strictly used the local storage for ISOs and the Proxmox system itself. This system ran excellently and never gave me so much as a hiccup. The combination of super fast BIOS and the SSD boot volume meant that this thing would boot or reboot so fast that I had to double check that I actually shut it down, quite a nice problem to have.

As so often happens here at the home office lab, I change hardware pretty frequently. Often times it is due to client needs or desires, other times it’s simply that I see something new and shiny. Regardless of the reasons, I rarely regret the money spent as the investment always comes back many times over in the form of education and experience gained.

This i3 system was eventually replaced about a year later when someone I knew really wanted the i3 NUC so I sent it packing to a new and better home. Since I had grown accustom to the silence, low power/heat, and wonderfully small size of the NUC, I had to find something like it to replace the one I had just gotten rid of. Well, after little debate, I ordered a new Intel NUC again, this time armed with a higher clock speed and the wondrous Core i5 badge. System memory was boosted to the full 16GB allowed by the board and off I went. Just like its Core i3 counterpart, this NUC performed flawlessly in all regards. Stable, fast, and truly affordable.

If you are looking for low power (as in electricity consumption), high performance, and physically small and beautiful package for your home lab test machine/hypervisor, be sure to take a serious look at the Intel NUC. Just imagine a shoe box full of Intel NUCs acting as a full on Proxmox cluster! Aside from the physical memory constraints inherent to this platform, I have seriously considered putting a handful of these into client networks as small foot print Proxmox clusters.

Pros: Tiny system, low energy usage, high performance.
Cons: Usually a tad more expensive than a comparable i3/i5 SFF desktop PC with the same specs. Requires mSATA and low voltage memory, both of which you probably do not have laying around.

A final note, unless you are doing CPU intensive tasks, which you probably are not, then skip the i5 variant. While it works great, I noticed zero performance increase over my Core i3 NUC. Obviously, this varies from workload to workload so be sure you know what you need.

I hope this helps any perspective home lab enthusiasts out there and be sure to stay tuned for my next build which I just finished ordering…
