E100-9W – A new fanless Supermicro “NUC” platform

01/19/2021 by William Lam 10 Comments

At the end of 2020, I had published a blog article which covers the latest Supermicro kits that are being used and others that can be used for both VMware Homelabs as well as for production workloads. The article was very well received, especially as this is a topic that I frequently get questions about on the latest hardware kits that will work with vSphere, vSAN and NSX-T.

While researching for the article, I had a chance to speak with the Supermicro Product Manager and I came to learn about a new E100-9W platform that was just released last Spring of 2020. This platform is part of Supermicro's Embedded IoT family of servers and focuses on use cases such as Industrial Automation, Retail, Smart Medical Systems, Kiosks and Digital Signage to name a few. Many of these use cases are also applicable to our VMware customer base, especially for running a small and lower power footprint at an Edge or ROBO location. I was also interested in this platform as it could also be interesting for VMware homelabs.

ESXi on 11th Gen Intel NUC (Panther Canyon) & (Tiger Canyon)

01/13/2021 by William Lam 16 Comments

The highly anticipated 11th Generation Intel NUCs based on the new Tiger Lake processors has just been announced by Intel and I am excited to share my first hand experience with this new NUC platform. There are currently two models in the new 11th Gen lineup: the Intel NUC 11 Performance codenamed Panther Canyon (pictured on the left) which is the successor to the 10th Gen (Frost Canyon) NUC and the Intel NUC 11 Pro codenamed Tiger Canyon (pictured on the right) which is the successor to the 8th Gen (Provo Canyon) NUC.

There are a number of new improvements and capabilities that will make these new NUCs quite popular for anyone looking to build or upgrade their vSphere environment in 2021.

Before diving right in, I must say I love the new aesthetic look of the NUC chassis. In previous versions, the lid had a glossy and shiny finish, which easily left hand prints. These new models now have a clean matte finish. The NUC 11 Performance has a smoother feel compared to the NUC 11 Pro which has more of a texture to the finish, which I personally prefer. The other noticeable change is the power adapter, which is now half the size now which is nice for those looking to have several of these new kits sitting next to each other.

ASRock AMD “NUC” Gen 2 Platform

It has been about one year since I first got hands on with ASRock's first AMD "NUC" platform dubbed the 4x4 BOX.

A couple of months back, ASRock launched their 2nd generation of the 4x4 BOX platform which adds support for AMD's Ryzen 4000U series mobile processors with the introduction of the 4x4 BOX: 4800U (Ryzen 7), 4500U (Ryzen 5) and 4300U (Ryzen 3) models.

The exterior box looks much brighter and it oddly looks familiar … 🤔 All I can say, is good taste @ASRockUSA pic.twitter.com/GR0su7eFaR

One immediate difference between the original 4x4 BOX (right) is the slimmed down chassis design, which gives it that classic "compact" look of a traditional NUC. The updated design definitely looks cleaner.

Intel NUC with 512GB memory

12/03/2020 by William Lam 6 Comments

Yes, you read that correctly. 512 gigabytes of memory on an Intel NUC. Not only is this pretty 🤯 but this is actually possible today with an already released Intel NUC!

A few months back, I was made aware of some really cool technology from Intel called Intel Memory Drive Technology (IMDT) which leverages Intel Optane SSDs to extend memory of a system beyond its physical memory (DRAM) capacity. This technology is made possible with their IMDT software, which is a purpose built Hypervisor whose sole purpose is to just manage memory and this Hypervisor runs on top of the Intel Optane SSD. You can think of this like a Software-Defined Memory (SDM) solution. In fact, SDM was actually coined in this performance white paper evaluating IMDT with scientific-based applications back in 2018.

Note: This should not be confused with Intel Optane and its Datacenter Persistent Memory (PMEM) solution which vSphere already supports today.

The target use case for this type of technology is for memory intensive applications such as SAP HANA, Oracle, Redis, Memcache and Apache Spark to just name a few. These workloads can easily gobble up 10's of terabytes of memory that can bring a number of challenges when needing to scale up these solutions. High capacity memory DIMMS are not only expensive, but once you exhaust the number of physical DIMM slots, your only option for scale up is to add additional servers which is very costly.

Using IMDT, customers can expand their physical DRAM capacity from 8x to 15x, which can significantly improve cost, performance but also the operational overhead in managing additional systems. Putting aside the in-memory based workloads, I think there is also huge potential for general purpose workloads that can also get the exact same benefits, especially when you think about constraints like power, cooling and location such as Edge or ROBO locations. Since this solution works on an Intel NUC, a really interesting use case for this technology that immediately came to mind was for a vSphere/NSX/vSAN homelab environment.

ESXi 7.0 Update 1 now includes NIC driver for Intel NUC 10

09/21/2020 by William Lam 14 Comments

With the upcoming release of vSphere 7.0 Update 1 and specifically ESXi 7.0 Update 1, support for the onboard NIC of the Intel NUC 10 (Frost Canyon) is now included and the community ne1000 VIB driver is no longer needed. If you had previously installed the community driver, you can uninstall the VIB after successfully upgrading to ESXi 7.0 Update 1.

Disabling TPM 2.0 connection cannot be established message in ESXi for Intel NUC 10

08/21/2020 by William Lam Leave a Comment

For Intel NUC 10 (Frost Canyon) owners who have installed ESXi may have noticed that even after disabling Intel's Trusted Platform Module (TPM), the following warning message "TPM 2.0 device detected but a connection cannot be established." is still being displayed in the vSphere UI as shown in the screenshot below.

Thanks to Reddit member mscaff and casperette who recently discovered and confirmed that the latest BIOS (FN0044) resolves an issue where disabling TPM in the BIOS was not actually working which would explain the behavior observed above. The really interesting thing is that I had initially ran into this problem several months back and after speaking with some internal VMware folks, I was able to get rid of this message without this update. This involved installing Windows 10 and clear the TPM keys which may have still been cache but since then, it has not been reproducible by other folks. In any case, it is always recommended to check and update to latest BIOS to ensure you have all the latest bug fixes.

Lastly, Intel states support for TPM 2.0 for these NUCs, so why is ESXi complaining? Well, it has to do with the interface type and not with SHA1 vs SHA256 which are both supported on the NUC 10. The NUC only supports CRB but proper compliant TPM 2.0 chip must support FIFO which is not configurable the last time I had checked. For more detail requirements and configuration of TPM 2.0 on ESXi, please refer to this blog post.
