Syncing ZFS datasets between nodes In my cluster I use pve-zsync in 2 ways: Syncing an ISO store to all nodes Syncing some really important datasets to multiple nodes Let’s find out why and how to do this! The why My cluster is built on the “modern” notion that a node should be able to … Continue reading Proxmox and pve-zsync → The post Proxmox and pve-zsync appeared first on Intermittent Technology.| Intermittent Technology
Migrating ZFS datasets Once your new cluster is up and running and you want to move over data sets from an old server/node to a new one, how do you do that? The method I’ve come up with is the following….. Snapshot all datasets First we’re going to make an initial snapshot, replicate that and … Continue reading Proxmox ZFS migration → The post Proxmox ZFS migration appeared first on Intermittent Technology.| Intermittent Technology

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 … Continue reading AMD X870e Storage Considerations and tests/benchmarks →| Intermittent Technology
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 … Continue reading Expansion slots and 10Gbit networking options (including WiFi slot!) → The post Expansion slots and 10Gbit networking options (includi...| Intermittent Technology
Buy new or second hand Enterprise? Home Server Cluster 2025 index For a long time when running home servers it’s been normal to use older Enterprise hardware, is this still the correct choice in 2025? Let’s explore this. 2 examples most people probably know about: Need more SATA Ports?

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 … Continue reading →| Intermittent Technology
