Hi, I bought an M720q with a Pentium Gold and upgraded it with a Core i7 8700 (65W). Everything runs smoothly under Windows the CPU briefly pulls up to 45W and then settles down to 35-37W, with temperatures averaging at 75°C / peaking at 80°C under full load. This is exactly what I expected...

Let's start by saying that if I'm in the wrong forum please let me know so I can ask this question in the right place. This is the first time building a home server and I would like it to be a file server, plex, and home assistant machine. Is there an OS that would best be suited for this...

Hey folks, I have 3 servers equipped with the Connect-X2 MT26418, all running Proxmox (debian11). The cards are all 2 Port ones, and I got 2 cables running between them like this: +---------------------------+ | serv1 | +---------------------------+ | Port 2 |...

So this is fun, I just woke up to a clone job of my laptop being finished, it was kind of an experiment. It runs OpenSUSE, so it's got a BTRFS root and snapshots triggered by package manager. I wanted to back it up so I could have a copy of the machine to run elsewhere, here's how I did it...

Hello, I'm a complete newbie when it comes to building servers so please be patient :) Recently I decided to build a server which would be used for storage, but also as a workstation where I would have multiple virtual machines for testing/gaming/audio production. After some research it seems...

Hey, curious about how to get distributed volumes to span several devices. Unfortunately haven't seen much literature about this. I'm actually using Ubuntu instead of Oracle Linux, but the setup procedure appears virtually identical. Here's what I'm following, which seems to be the best...
