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.

Complete vSphere with Tanzu homelab with just 32GB of memory!

11.09.2020 by William Lam // 42 Comments

Since the release of vSphere 7.0 Update 1, the demand and interests from the community on getting hands on with vSphere with Tanzu and the new simplified networking solution, has been non-stop. Most folks are either upgrading their existing homelab or looking to purchase new hardware that can better support the new features of the vSphere 7.0 release.

Although vSphere with Tanzu now has a flavor that does not require NSX-T which helps reduces the barrier on getting started, it still has some networking requirements which may not be easily met in for all lab environments. In fact, this was actually the primary reason I had started to look into this since my personal homelab network is very basic and I do not have nor want a switch that can support multiple VLANs, which is one of the requirements for vSphere with Tanzu.

While investigating for a potential solution, which included way too MANY hours of debugging and troubleshooting, I also thought about the absolute minimal amount of resources I could get away with after put everything together. To be clear, my homelab is comprised of a single Supermicro E200-8D which has 128GB of memory and that has served me well over the years and I highly recommend it for anyone that can fit that into their budget. With that said, I did set out with a pretty aggressive goal of using something that is pretty common in VMware homelabs which is an Intel NUC and with just 32GB of memory.

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

09.21.2020 by William Lam // 16 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.
