The ESXi server upgrade was quick and problem-free, but the vCenter upgrade was more like a roller coaster for my two vCenters. Both had some issues, but now I will explain in detail what the problems were and how I resolved them. First Error: Pre-upgrade check resultError:Source vSphere ESX Agent Manager (EAM) upgrade failed to…
Improving Sleep: Bed Cover Care, Room Setup, and Natural Wake-up Methods

The Benefits of Morning Gym Workouts for Achieving Life Goals
Exercise is very important for how we feel and what we can achieve. This is similar to food. Today’s workout will affect us the next day, influencing how we feel and how well we feel. I recommend going to the gym at least five times a week. For me, the best time to work out…
The Crucial Connection: Healthy Diet and Productivity for Tomorrow

Just as poor-quality fuel can cause a car to run badly and encounter various problems, eating unhealthy food can have similar negative effects on your body. Imagine heating a sauna with all kinds…
AI, ML, and vGPU Server Build – Part 3: The Server Case as a Double-Decker Bus
Those two mining frames in the photo illustrate my idea well, but I plan to use a PC case and build a frame on top of it where I can easily attach different GPUs, essentially connecting 2 PC cases together. The server motherboard is secured inside the PC case, and the GPUs are openly mounted…

Dell S4112T-ON: Cooling and silencing the fan noise of a 100 GbE switch
I’ve had this switch for a long time and I’m very satisfied with it. They say a picture is worth a thousand words, so I’d rather share pictures of how I rebuilt a very noisy data center top rack switch. The switch originally came with a powerful 3-fan setup designed for data centers, which I…

Initially, the plan was to buy and assemble this server during 2024, but fortunately, I achieved it earlier. Buying from abroad becomes many times more expensive in 2024,…
