Quick Tip - Additional NVMe vendors (SK Hynix & Sabrent) for ESXi homelab

by // 12 Comments

The Samsung 980 Pro NVMe is a pretty popular SSD model that is used by many within the VMware Homelab Community. However, in recent months, there have been an alarming amount of reports from owners that their 980 Pro NVMe devices have been failing prematurely due to firmware issues.

Samsung has finally acknowledge the problem with a firmware fix and it looks like a simliar fix is also planned for the Samsung 990 Pro NVMe.

While I can not comment on the specific issues with the Samsung 980/990 Pro NVMe devices, I have had my own failures with cheaper Samsung M.2 NVMe devices where I lost my vSAN setup since I only had a single vSAN diskgroup comprised of single cache and capacity SSD for my homelab. While not ideal, this is to be expected since I had no redundancy and consumer hardware can and will fail over time. I ended upgrading both of my SSDs to a Samsung 970 Plus, which luckily is not affected by the firmware issues.

I typically recommend Samsung, Intel and Western Digital NVMe devices as they typically just work with ESXi, especially for homelab purposes where cost is one of the factors. From some of the online posts that I have read about the current Samsung 980/990 Pro issues, it seems that many have lost faith in Samsung and some have even stated that they will no longer consider Samsung for storage purchases.

This was also a simliar sentiment when I recently spoke with a fellow VMware colleague who was also impacted by the firmware issues. As part of our discussion, he had shared a couple of alternative vendors that he has is now using and recommending for his VMware Homelab setup which also includes vSAN. I thought this was good information that could also benefit folks in the community looking for other storage options.

How to bootstrap ESXi compute only node and connect to vSAN HCI Mesh?

by // Leave a Comment

After documenting the process for bootstrapping vSAN Express Storage Architecture (ESA) using my Intel NUC 12 Pro, I was looking for an easier way to share my physical vSAN storage, which is powered by a single Supermicro E200-8D, to other physical ESXi hosts for testing purposes.

I had recently been playing with the vSAN HCI Mesh feature, which was launched back in 2020, as I was running out of spare NVMe devices when needing to test different physical hardware kits. While my use case for the storage is typically short lived, it means I do not have to play musical chairs with the limited number of NVMe devices I have installed in the various kits I have.

The vSphere UI in vCenter Server already provides a very simple workflow to mount a remote vSAN storage on an ESXi compute-only node, but I was also looking at this from a bootstrapping point of view and what if vCenter Server was not deployed or even available? Could I still make this work? After a bit of trial and error, I was able to figure out this can be accomplished by using a series of ESXCLI commands!

ESXi on AMD ChangWang CW56-58

by // 40 Comments

It can be pretty difficult to find an AMD-based small form factor (SFF) kit that is compatible with recent ESXi releases. The large majority of these AMD SFF kits all use Realtek for their onboard network adaptor and Realtek does not have a driver for ESXi, nor have they expressed any interests in creating one.

This is also quite unfortunate, as there have been some pretty interesting AMD kits that have been released in the market, but they can not be fully utilized due to the network driver challenges. Prior to the holiday break, fellow VMware colleague Hilko Lantinga, who works in our End User Computing (EUC) division had reached out about a new AMD kit that he had just acquired and has been very happy with after putting it through its paces, especially from a power efficiency standpoint for his updated VMware Homelab.

The system is from a vendor called ChangWang, which I was not familiar with and the AMD kit is the CW56-58, which is based on an AMD Zen 3 architecture (7nm) and what stands out immediately is that this system includes four built-in network adaptors (hint: they are all compatible with latest ESXi 8.0 release)! I asked if he would be willing to sharing his thorough review with the community as this could be a really interesting system and below is Hilko's detailed write-up in his own words.
