sixdonuts··on New 10 GbE USB adapters are cooler, smaller, cheaper
Running a new cable is easy. You just use the old cable to pull the new cable. You can run composite cable if you desire copper, fiber and power.

25GB switches do 1/10/25GB, can be used with copper and fiber, use a magnitude less in power per port than a 10GB copper switch and cost the same or less per port than existing 10GB copper switchs.

Fiber is way easier to run than copper. If you already have copper just use that to run the fiber.

10GB ethernet switches will never be cheap because of the power requirements. Just get a 25GB switch and skip 10GB all together.

The Microtik in the link draws 15 watts at idle...

If you need 1G or 10GB over copper you can just use a SFP or SFP+ media converter in a 25GB SFP28 switch port. If you have a POE requirement, say for video cameras you either use a dedicated 1GB POE switch or power injector. A 10GBASE-T (RJ-45 copper) switch consumes 3-12 watts per port and a 24 port switch will idle at 50 to 60 watts and run hot. SFP+ and SFP28 ports use under 1 watt per port. I would never recommend a 10GBASE-T copper switch for any use case in this day and age, home or enterprise.

Yep, 10gb over copper is not power efficient so any savings you get from getting a cheap 10gb switch will just go to your power bill. Most cost effective and flexible is a used 25gb switch. Most 25gb switches can do 1/10/25gb. 10gb networking has been dead for over 10 years.
sixdonuts··on Go ahead, self-host Postgres
Thousands of orgs have full stack OT/CI apps/services that must run 24/7 365 and are run fully on premise.

News is one thing, if the app/service down impacts revenue, safety or security you won't be getting any sleep AWS or not.

No doubt. Reading this thread leads me to believe that almost no one wants to take responsibility for anything anymore, even hiring the right people. Why even hire someone who isn't going to take responsibility for their work and be part of a team? If an org is worried about the "bus factor" they are probably not hiring the right people and/or the org management has poor team building skills.
sixdonuts··on A Love Letter to FreeBSD
Some of the largest orgs have large amounts of IT infrastructure for OT and ISS that is not connected to the Internet. This infra is air gapped or often times on a completely separate physical LAN which is not accessible without passing through multiple physical security controls.
sixdonuts··on A Love Letter to FreeBSD
There are a lot of OT, safety and security infrastructure that must be run on premise in large orgs and require four to five nines of availability. Much of the underlying network, storage, and compute infra for these OT and SS solutions run proprietary OSs based on a BSD OS. BSD OSs are chosen specifically for their performance, security and stability. These solutions will often run for years without a reboot. If a patch is required to resolve a defect or vulnerability it generally does not require a reboot of the kernel and even so these solutions usually have HA/clustering capabilities to allow for NDU (non disruptive upgrades) and zero downtime of the IT infra solution.

The BSD/Illumos OSs are used quite frequently as the base OS for high end commercial/enterprise network, SAN, NAS etc. solutions. They are chosen for it's performance, stability and HA features.
sixdonuts··on Using FreeBSD to make self-hosting fun again
Yep, started on PF and the Palo and NSX FWs I use at the day job are a piece of cake.

Good stuff - thanks for sharing. IaC and containers are great but having the ability to run multiple VMs and create snapshots prior to performing upgrades or security patches is still very helpful from an operational perspective.
sixdonuts··on Shaving is too expensive
Shaving is not expensive if you simply clean the blade after using it. Cleaning the blades slows the oxidation process on the edge which is the primary contributor to poor blade performance.
sixdonuts··on Ceph: A Journey to 1 TiB/s
Just get a 25G switch and MM fiber. 25G switches are cheaper, use less power and can work with 10 and 25G SFPs.
sixdonuts··on The first Oxide rack being prepared for customer shipment
Additionally, compared to AWS Outposts which use inefficient commodity hardware and closed source software, the Oxide platform uses integrated hardware and software, and open source software.

Congratulations on your release! Great product. This will totally fill our MANY on-premise CI, Security, analytics and Video needs that CANT be moved to the cloud. Oxide will definitely be on our short list for our next hardware/software stack refresh.
