I dunno when it happened but I swear SBCs were the new best thing in the universe for a while and everyone was building cool little servers with their RockPis and OrangePis.
Now it’s all gone x86 and Proxmox with everyone shitting on Arm. What happened? What gives?
Is my small army of xPis pointless? What about my 2 Edge routers?
I’ve got about 6 xPis scattered round my flat - is there anything worth doing with them or should I just bin them?
All thoughts, feelings and information welcome. Thank you.
What happened is that people realized what I’ve been saying since ever - that the RPi and others are a money grab because of all the required accessories while a MiniPC will get you way more power, stable hardware , case, power supply and everything in between for the same price (if you go for second hand). Here is are examples of such posts: https://lemmy.world/comment/5357961 , https://lemmy.world/comment/4696545
Either way, Pis have their use cases however in my opinion it was an overhyped product that sits on the middle of a market:
Proxmox isn’t a new thing, in fact it is a pile of crap and questionable open-source that people still run because they haven’t discovered LXC/LXD yet. Read more here: https://lemmy.world/comment/6507871. FYI you can run LXD on your Pis and get both containers and virtual machines with it in the same way Proxmox people do with x86.
The irony of this comment is that people will shit on me about replacing Proxmox with LXD in the same way they used to when I said that Pis were a money grab and x86 MiniPCs were way better.
The mian issue with Mini/used PCs is the power efficiency. It’s just a waste of wattage and performanve/Watt is very bad, especially at idle.
I would agree to a certain point. If you get a 10th gen CPU it is power efficient and there are a lot of gamers and whatnot selling those. Also there are a lot of MiniPCs that come with mobile “T” CPU that are very decent at idle.
But idle still would run much more than 15w. There a very good compilation google sheets for the most efficient X86 cpus, but once you start factoring hdds and ssds, it’s only natural to go higher (20w-30w) at least. That’s at least double than rpis
Do you think the used server market is worth the cost? It looks like I could have a giant chunk of DDR3 for not so much.
I don’t (specially DDR3-era stuff) because old server hardware is way more expensive, won’t be of any particular advantage and older hardware, compared to new stuff, will use a LOT of power.
Instead use regular desktop/laptop machines as they’ll probably be more than enough for homelabs. You can a good 9-10th gen Intel CPU and motherboard that is perfect to run servers (very high performance) but that people don’t want because they aren’t good to play the latest games. Modern hardware = less power consumption, cheaper, more performance.
If you go really low end, let’s say i5-6500, this will probably cost around 80€ second hand with RAM. You can use https://www.cpubenchmark.net/compare/ to compare CPUs the server hardware you can get with modern hardware if you’re interested.
Most DDR3-era server hardware comes with RAID controllers/cards and other things that nobody uses anymore, people have moved on the software RAID be it BRTFS or ZFS and you will want to do the same. Servers make a lot of noise - impractical for a home - and a CPU from that era will be around 150-200W, you can get a recent i5 with more performance that runs around 50W.
Another thing to consider: you’re trying to build a NAS get a basic motherboard with 4 SATA ports and then add a PCI to 5 SATA port card and it will be much cheaper than whatever server hardware. BTRFS as your filesystem and its RAID if needed. Now you may be thinking something like “I want a faster CPU in order to have fast SMB”, just don’t - your gigabit network will saturate before an i5-6500 or any mechanical drive does and when this happens you’ll be at something like 10-20% CPU usage. Just don’t waste your money.
Quite the teardown fair play
