After going over the hardware selection in my previous post, we still need to get power to the servers…
The power system is going to be a difficult part of this build… As I wrote earlier, I am not a DYI person and I’ve been on the receiving end of enough electric shocks that, frankly, electricity scares me. But there is no way I can use discrete power supplies for every motherboard because: Continue reading “Building a mini cluster – Part 3: One power supply to feed them all…”
Following my previous entry, where I went over the Design Criteria for my mini cluster, the next step is the selection of the server hardware: processor and motherboard, memory and storage.
Since I will be needing twelve of everything, even a small cost difference of “only” 10.00 EUR immediately means a total extra cost of 120.00 EUR… Penny saving matters! Continue reading “Building a mini cluster – Part 2: Server Hardware Selection”
Ever since I can remember, I’ve had easy access to some form of multi node compute environment . But after changing jobs earlier this year, I found myself without access to anything resembling a cluster. At first it was only mildly annoying and I made do with using virtual machines on my (rather beefy) PC and I dabbled with public clouds like Azure and Amazon when I got a free coupon at some convention. But recently, I needed a cluster environment to test something for a potential customer and much to my chagrin, every virtual environment I tried just did not want to cooperate.
So I made the solemn promise to myself:
I will never be at the mercy of virtual compute ever again!
