Deploying a MinIO SNMD Object Storage Server in TrueNAS SCALE

[ Preamble ] This deployment of MinIO SNMD (single node multi drive) object storage server on TrueNAS® SCALE 24.04 (codename “Dragonfish”) is experimental. I am just deploying this in my home lab for the fun of it. Do not deploy in any production environment.

I have been contemplating this for quite a while. Which MinIO deployment mode on TrueNAS® SCALE should I work on? For one, there are 3 modes – Standalone, SNMD (Single Node Multi Drives) and MNMD (Multi Node Multi Drives). Of course, the ideal lab experiment is MNMD deployment, the MinIO cluster, and I am still experimenting this on my meagre lab resources.

In the end, I decided to implement SNMD since this is, most likely, deployed on top of a TrueNAS® SCALE storage appliance instead an x-86 bare-metal or in a Kubernetes cluster on Linux systems. Incidentally, the concept of MNMD on top of TrueNAS® SCALE is “Kubernetes cluster”-like albeit a different container platform. At the same time, if this is deployed in a TrueNAS® SCALE Enterprise, a dual-controller TrueNAS® storage appliance, it will take care of the “MinIO nodes” availability in its active-passive HA architecture of the appliance. Otherwise, it can be a full MinIO cluster spread and distributed across several TrueNAS storage appliances (minimum 4 nodes in a 2+2 erasure set) in an MNMD deployment scheme.

Ideally, the MNMD deployment should look like this:

The True Value of TrueNAS CORE

A funny thing came up on my Twitter feed last week. There was an ongoing online voting battle pitting FreeNAS™ (now shall be known as TrueNAS® CORE) against Unraid. I wasn’t aware of it before that and I would not comment about Unraid because I have no experience with the software. But let me share with you my philosophy and my thoughts why I would choose TrueNAS® CORE over Unraid and of course TrueNAS® Enterprise along with it. We have to bear in mind that TrueNAS® SCALE is in development and will soon be here next year in 2021.

The real proving grounds

I have been in enterprise storage for a long time. If I were to count the days I entered the industry, that was more than 28 years ago. When people talked about their first PC (personal computer), they would say Atari or Commodore 64, or something retro that was meant for home use. Not me.

My first computer I was affiliated with was a SUN SPARC®station 2 (SS2). I took it home (from the company I was working with), opened it apart, and learned about the SBUS. My computer life started with a technology that was meant for the businesses, for the enterprise. Heck, I even installed and supported a few of the Sun E10000 for 2 years when I was with Sun Microsystems. Since that SS2, my pursuit of knowledge, experience and worldview evolved around storage technologies for the enterprise.

Open source software has also always interested me. I tried a few file systems including Lustre®, that parallel file system that powered some of the world’s supercomputers and I am a certified BeeGFS® Systems Engineer too. In the end, for me, and for many, the real proving grounds isn’t on personal and home use. It is about a storage systems and an OS that are built for the enterprise.
