Proxmox multi-NIC configuration

Running Proxmox with multiple network connections

I have a Proxmox cluster running with 3 nodes and I have 2x 10Gbe interfaces per machine, one for my internal backend network for the cluster communications and storage replication and one for my normal LAN traffic.

But I want both sides to be accessible from several other subnets and VLANs but normally you can only have a single gateway, how to configure this?

AMD X870e Storage Considerations and tests/benchmarks

I recently upgraded my 5 year old computer from a AMD Ryzen 5950x to a AMD Ryzen 9950X3D together with everything that comes with that, new motherboard, new memory, etc..

As a storage minded person I wanted to get the “ultimate” storage setup for what was possible! Turns out the X870e chipset has some quirks to take into account! Let’s go through it including some benchmarks for the Samsung 9100 PRO and the Samsung 990 Pro!

Expansion slots and 10Gbit networking options (including WiFi slot!)

Expansion slots and 10Gbit networking options (including WiFi slot!)

Normally building a system based on a Micro-ITX board limits your available IO options heavily. You are basically dependent on whatever comes on the motherboard + 1 PCIe x16 slot.

While the same holds true for the system we are building, using some smart modern trickery we can actually get quite a lot of IO and more importantly PCIe lanes out of it!

Let’s explore that a bit and see what our options are, but with this method you’ll be able to get multiple unrestricted 10Gbit ports + NVMe SSDs and SATA drives without a problem!

Calculating power requirements

Calculating power requirements

Home Server Cluster 2025 index

When building a system you need to do some power requirements guesstimates, most often this doesn’t have to be very precise and especially when building a normal form factor PC or server, the power supply is often heavily oversized anyway.

However when trying to build a performant but energy efficient system, things become a little bit more critical. Especially when you really start taking a look at see how much power you are going to need on the 12v and especially 5v rail.

Let’s explore!

Fully designed hardware for the nodes

The hardware the nodes will use

Home Server Cluster 2025 index

Nowadays you have lots of options when building a PC, you can choose between Intel and AMD, within their lineup they have various generations and types (mobile, desktop, prof, server, etc.) and then you have various motherboard vendors, lots of different cases, power supplies, and the list goes on, what combination will get you what you need?

It’s hard to say what *you* need, below is what I think that, at the time of writing, is ideal for my situation to get a good combination of Performance, power usage and expandability.
