Intel NUC with 512GB memory

12.03.2020 by William Lam // 7 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.

Intel NUC 9 Pro & Extreme - First "Modular" NUC

01.07.2020 by William Lam // 27 Comments

The highly anticipated "modular" Next Unit of Computing (NUC) has just been announced at the Consumer Electronic Show (CES) this week, dubbed the Intel NUC 9 Pro (codename Quartz Canyon) and NUC 9 Extreme (codename Ghost Canyon). Boy am I super excited for this new platform and what it could mean for the VMware Community! 😍

Immediately off the bat, you can see that this is not your typical NUC "cube" form factor. Intel has completely redesigned the system from the inside and out, more on this in a bit. The key difference between the two NUC 9 variants (Pro and Extreme) are the CPU options, which are detailed below. For the remainder of this article, I will be focusing on the Pro version of the NUC 9 and I will call out any differences where applicable.

The use of the word "Pro" is also quite fitting as Intel is positioning this system as a high-end prosumer to Mid-Enterprise device compared to the traditional NUC. The NUC 9 Pro is targeting more demanding workloads such as Digital Content Creation, CAD/Manufacturing and Financial Service applications that either require a high-end graphics card or AI module for computing. When I first heard about this system from Intel, it conceptually reminded me of Apple's recent 2019 Mac Pro, which is also designed with modularity in mind and can cater to a variety of use cases.

Speaking of use cases, although Virtualization is not a target use case for this new platform, VMware customers have been taking advantage of the Intel NUCs for a number of years now and it is still by far the most popular platform for running a vSphere/vSAN/NSX Home Lab. However, one common complaint I often hear about the current generations of NUCs has been its CPU and I think the new NUC 9 Pro/Extreme will be a nice contender for current alternatives like the popular Supermicro E200-8D. Thanks to Intel, I was able to get my hands on a pre-production NUC 9 Pro unit for testing, so lets take a closer look at what this new platform has to offer!

Dual Intel M.2 Optane 4801x in Supermicro E300-9D

01.14.2019 by William Lam // 11 Comments

For those that have been following along, I have been testing the Supermicro E300-9D (SYS-E300-9D-8CN8TP) kit in my home lab which I have written about here. One of the last things I was looking into was storage expandability with this platform, especially since Supermicro has a PCIe Add-On Card (AOC-SLG3-2M2) which can add two additional M.2 devices supporting 2260 (60mm), 2280 (80mm) & 22110 (110mm) form factors.

At the same time, our friends over at Intel had just given me access to a couple of their pre-release Intel M.2 Optane 4801x devices which were then released right before the holiday last year. For those wondering why Optane is so interesting, especially from a vSAN perspective, check out this blog post here from my good buddy Pete Flecha over in our Storage and Availability Business Unit (SABU).


This was actually perfect timing as I was also interested to see if there were any high performance and supported M.2 devices that could be used for for vSAN Caching and this device would definitely fit the bill! When I had initially received all the components, I was scratching my head as the AOC was too big to fit horizontally in the E300-9D.
