About Proxmox Lab
Proxmox Lab focuses on Proxmox VE clustering and Ceph operations: quorum planning, two-node QDevice voting, redundant Corosync links, storage availability, and capacity for recovery after a node failure. VMware migration coverage connects an existing estate to that target-cluster plan.
It is written for people designing a cluster before they build it, and for people diagnosing one that has stopped behaving. Every figure comes from the Proxmox VE administration guide, the Corosync and Ceph documentation, or the vendor's own published pricing and licensing terms, and each article links the source it used.

4 articles are published so far. New articles are announced on the RSS feed; there is no fixed publishing schedule and this site does not promise one.
How these articles are produced
Articles are researched from primary sources: vendor and project documentation, published standards and specifications, release notes, advisories, and measurements published by the people who took them. Drafts are produced with AI assistance and then edited against those same sources before anything is published. Where a figure comes from a datasheet or a third-party measurement, the article names the source and links to it so you can check the original rather than take this site's summary of it.
Everything here is published under the Proxmox Lab Editorial byline. That is an editorial desk, not a person, and no article on this site claims hands-on lab testing, benchmarking, or first-hand measurement. Nothing here should be read as a report of something this site physically tested.
Corrections
Getting it right matters more than getting it first. If something on this site is wrong, out of date, or missing the source it should cite, email editor@proxmoxlab.org with the page and the specific claim. Substantive corrections are made on the page itself rather than quietly dropped.
How this site is funded
This site currently runs no affiliate links, no sponsored content, no paid placement, and no display advertising. Nothing on it earns a commission. If that changes, this page and the disclosure page will say so before any such link appears.
The full position is on the disclosure page. Read it before acting on anything here that reads like a buying recommendation.
