Project USB to SDDC - Part 2

by // 1 Comment

In the previous article, I provided some background on the origin of the project. In this article, we will now focus on the technical details and how the solution actually works.

Hardware

This solution was originally developed against an Intel NUC but I had designed it to be generic so that it could run on any system which meets the minimum requirements which is just having two disks (HDD & SSD or two SSDs) which is used to create a vSAN datastore.

Here is the BOM for the Intel NUC that we had used:

During the Sydney VMUG, we had did a live demo using an Intel NUC. Prior to the Melbourne VMUG, fellow VMware colleague Tai Ratcliff reached out and offered to let us borrow his Supermicro kit for the demo which was great as the hardware was much beefier than the NUC. Thanks Tai!


I had already been hearing great things about E200-8D platform but I had not had the opportunity to get my hands on the system to play with. After only spending a little bit of time with the platform while prepping for the VMUG event, I can see why is a pretty slick system for a vSphere/vSAN based home lab, especially if you need to go beyond 32GB of memory which is where the Intel NUCs currently max out at.

The other appealing features for this platform is that it comes with 2x10GbE, 2x1GBe and an IPMI interface for remote management which is a huge benefit for not needing to connect an external monitor and keyboard. The system is also Xeon based w/6-Cores and can go all the way up to 128GB of memory. Tai had also recently published a blog article comparing the Supermicro E200-8D and the Intel NUC, which I think is worth a read if you are deciding between these two platforms.

Project USB to SDDC - Part 1

by // 2 Comments

A couple of weeks back, Alan Renouf and I co-presented at the Sydney and Melbourne VMUG UserCon, here are some great write-ups about the events here and here. We were very honored to have been invited out and to also deliever the closing keynote. Having traveled halfway around the world, we thought it was only fitting to share something really special.

For the last couple of months, we had been working on a small pet project that I personally had been referring to as the "vGhetto SDDC". This was not something we had not shared with anyone before and thought the VMUG UserCon was the perfect venue to demo our new project. For the session, we decided to rename the project/session to USB to SDDC (better ring than the previous title) which might give you a hint on what the project might be about.

The inception for this project really stemmed from the work we did at last years VMworld Hackathon which was another idea that both Alan and I had came up and worked with the VMware Code team to deliver at both VMworld US and Europe. Like all great Automation stories, the motivation for this project was born out of pure laziness. With the huge success of the Hackathon at VMworld US, there was a huge demand for us to also deliver it again at VMworld Europe.

No suitable disk was found when upgrading to ESXi 6.5 on USB?

by // 10 Comments

I got a question from my buddy Paudie O'Riordan this morning where he was noticing a strange issue while trying to upgrade his ESXi hosts from 6.0 to 6.5 (all on the VMware HCL). Like many of our customers, he runs ESXi on USB device and when he attempted to upgrade using ESXi Scripted Install (Go Automation!), he was surprised to find that his USB device was not being detected.


Interestingly, I had literally just finished answering a similar question on our internal Socialcast forum and I had wondered if Paudie was also seeing the same problem. The issue looks to be related to the new USB Native Driver (vmkusb) that was introduced in ESXi 6.5 where is it is unable to claim the specific USB device.

Although you can disable the USB Native Driver and fall back to the legacy driver as mentioned in this VMware KB 2147650, but because this is happening during the installation/upgrade process, it can get a bit tricky.
