The hardware market has started to recover, and with vSphere 8.0 introducing native support for the excellent Intel i226-V network card, some new contenders have arrived in terms of price to performance that generally should be able to run ESXi. This post will focus on several categories, including mini PCs, second hand workstations and servers, and whitebox builds that should meet the requirements of the updated HCL. Let's get started!
NUC like systems are a classic piece in the homelab. Historically, the tradeoff has been limited network connectivity and/or lack of compute/memory density. Now, however, there are some exceptions to the rule.
Topton, a 6 year old shop on AliExpress, has an AMD Ryzen 5000 series based "router" which grants 6 to 8 cores, up to 64GB of RAM, 3x M.2 NVMe slots, and four i226-V based 2.5Gbe ports. With an entry point of $346 USD at the time of this writing, along with a claimed capability to ship VAT/Tax free (not verified, YMMV), this looks like it could be the value king mini PC of 2023. Be wary of copycat shops who may offer similar specs at a higher discount; ensure that the store has been around for some time as not every seller can be trusted. Intel based systems can also be found with similar specs (minus the awesome core count, of course) for ~$200 USD for super cheap vSAN clusters.
Sadly, mini PCs still suffer from a lack of PCI lanes, but I found a creative way around this... that's reserved for a follow up blog.
Second hand workstations
With buying cycles slowing down in an uncertain economy, second hand hardware is getting harder and harder to come by. Workstations, however, are sometimes offered up on eBay for a deep discount. Most of the hardware in these are supported by ESXi, with perhaps an exception for the onboard network card. Fortunately, to make up for this, they have several PCI-E slots, so adding a supported NIC isn't too much of a hassle.
The Dell Precision T7820 and T7920 can sometimes be found with Xeon Bronze or Silver processors in the sub $500 USD range. Recently, I saw a 2x Silver with 64GB of RAM listed for $350 USD. The HP equivalent Z6 G4 and Z8 G4 can be found for similar price points. Both of these *should* come with an Intel based on board NIC according to their drivers on their respective support pages. Be wary of barebone kits, as these systems do not have onboard graphics - a barebone system with no GPU will require a graphics card to function properly.
Looking forward to the future of Threadripper based workstations - The Dell Precision 7865 can pack up to 64 cores in a standard ATX tower form factor. Definitely not cheap, but exciting to see nonetheless!
Second hand servers
As of this writing, the same issue that is faced with workstations is impacting servers ten fold. Most hardware vendors are officially ending support for socket 2011-3 based servers, such as PowerEdge 13G, HPE Proliant G9, and Cisco UCS M4 systems. These are also falling out of support with ESXi 8.0, as they were originally introduced in 2014. The next generation of each (14G, G10, M5) are difficult to find on eBay for a decent price. I'll post an update to this in another blog post later this year, as I expect more second hand hardware will drop in price closer to the EOL of the older generations.
White box builds
Building out hardware that is intended for gaming and enthusiast builds has some caveats. Most gaming systems use a Realtek NIC for gigabit or 2.5Gbe networking onboard. These cards are not supported with ESXi as there is no compatible driver. Our options are:
- Find a board with i226-V onboard (i225 for most gaming boards had many issues, regardless of revision)
- Add a supported USB NIC with the Fling driver
- Add a supported PCI-e NIC (and/or HBA if using a CPU with onboard graphics enabled)
