Building a tiny Azure hub with VPN, firewall, and peered VNets Greetings! I’ve been tightening up my Azure homelab so that West US and West US 3 can both ride a single VPN gateway and still force traffic through an Azure Firewall. This is all in preps and hopes to get my AZ-700 exam completed…

IPV6 Setup with Comcast & Unifi Greetings! This past weekend I deployed IPv6 in my network at home. I’ve used IPv6 in the past, but I’ve never set it up from scratch. What do we need to do to set it up from scratch? Lets dive in. First, atleast with comcast, you need to make…

Greetings! In my lab I’ve been testing PCIE Passthrough for GPU based workloads (Cloud Gaming, and other CUDA based workloads). With ESXI 7.0’s release there was an addition called Dynamic DirectPath IO which is an option for GPU passthrough. I wasn’t sure what this was, so I decided to do some diving to find out.…

Greetings! As my work to support PyTorch equipped researchers continues I started working on a benchmark to compare hardware for our researchers. This benchmark is intended to help researchers make informed decisions about hardware for development purposes. I hope that this benchmark will be useful to others and will provide answers to any questions they…

Greetings! Recently I needed to export and backup EC2 instances offsite, to later be used in a different lab scenario. I thought this wasn’t actually do-able, until I learned about the aws ec2 create-instance-export-task command. Using some of my own code, and OpenGPT, I was able to whip up a script that does just that! The Code:…

I recently had to work on installing a Tesla K80 in a SUPERMICRO 1027GR-TRF triple GPU server. Then, I needed to install Ubuntu Server 20.04.5 LTS to run batch based GPU workloads. SUPERMICRO 1027GR-TR w/ E5-2670, 64GB RAM, and 1x Tesla K80 Lets see… What do we need to do to get this working? The…

During my testing of vGPU and GPU passthrough I ran into this an issue where I could not pass-through GPU’s with more than 8GB of VRAM. In my case my GPU in my ESXi host was a Tesla K80 (24GB VRAM). Luckily, I stumbled upon a great article by Stephen Wagner who outlined this great.…

Recently I’ve been tasked with working on a machine learning environment using ROCM, and AMD. I’ve never done this before… to the lab! The Intro I was able to purchase an AMD MI25 2nd hand card for 100$ USD (as of this writing). This device has plenty of horsepower for ML / AI lab work.…
