Infrastructure in a Nutshell
Replacing cluster drives should be a routine formality... until incompatible €500 caddies bring everything to a halt. Instead of putting up with the pro market's absurd prices and lead times, I decided to take matters into my own hands. Find out how 3D printing saved our SLA and our budget!
Those who've been following the blog for a while surely remember my "Maxi Best-Of Nutanix CLI" series. I loved writing it, and obviously, it saved the day for some of you more than once. But with the announced end of SSH connections on Nutanix clusters, the REST API is the admin's essential new Swiss Army knife.
If you've read my previous article detailing the architecture and technical stack I chose to deploy OpenClaw, today we're getting practical! I'm going to show you, step by step, how to deploy your own instance on a freshly installed Ubuntu virtual machine.
I wondered how I could connect artificial intelligence closer to my VMs. With this in mind, I got my hands on OpenClaw. Honestly, it was a bit of an obstacle course at the start.
With the future (and inevitable) blocking of SSH access on Prism Element and Prism Central, I had no choice: I had to seriously start learning the APIs...
I often get questions about this: how do you assign a physical graphics card to a VM in a simple and performant way? Today, I suggest we look together at how to deploy an NVIDIA Tesla P4 GPU on an Ubuntu Server 24.04 VM hosted on Nutanix AHV, using "Passthrough" mode.
AI-assisted coding, for a complete novice in development like me, is a revolution. It allows me to turn ideas into reality in a few hours where it would have been impossible before. Here's my honest feedback.
I will never forget the day the reality of hyperconvergence hit me. We were in the middle of an infrastructure migration. On one side, we had two full 42U racks from the 3-tier era, packed with servers and storage arrays. On the other side, to replace them, we only needed... 6U.
I've seen too many "cowboys" pull the plug or perform a brutal "Shutdown" via IPMI, thinking data resiliency would handle the rest. Spoiler alert: this often ends with Level 3 Nutanix support. This guide is my lifeline to ensure my cluster restarts without issues.
