I placed a low bid on an auction for 25 Elitedesk 800 G1s on a government auction and unexpectedly won (ultimately paying less than $20 per computer)
In the long run I plan on selling 15 or so of them to friends and family for cheap, and I’ll probably have 4 with Proxmox, 3 for a lab cluster and 1 for the always-on home server and keep a few for spares and random desktops around the house where I could use one.
But while I have all 25 of them what crazy clustering software/configurations should I run? Any fun benchmarks I should know about that I could run for the lolz?
Edit to add:
Specs based on the auction listing and looking computer models:
4th gen i5s (probably i5-4560s or similar)
8GB of DDR3 RAM
256GB SSDs
Windows 10 Pro (no mention of licenses, so that remains to be seen)
Looks like 3 PCIe Slots (2 1x and 2 16x physically, presumably half-height)
Possible projects I plan on doing:
Proxmox cluster
Baremetal Kubernetes cluster
Harvester HCI cluster (which has the benefit of also being a Rancher cluster)
Automated Windows Image creation, deployment and testing
Pentesting lab
Multi-site enterprise network setup and maintenance
Linpack benchmark then compare to previous TOP500 lists
25 machines at say 100W each is about 2.5KW. Can you even power them all at the same time at home without tripping circuit breakers? At your mentioned .12/KWH that is about 30 cents an hour, or over $200 to run them for a month, so that adds up too.
i5-4560S is 4597 passmark which isn’t that great. 25 of them is 115k at best, so about like a big Ryzen server that you can rent for the same $200 or so. I can think of various computation projects that could use that, but I don’t think I’d bother with a room full of crufty old PC’s if I was pursuing something like that.
I won’t be leaving all of them on for long at all. I’ve got a few basically unused 15A electrical circuits in the unfinished basement (can see the wires and visually trace the entire runs) I’ll probably only run all 25 long enough to run a linpack benchmark and maybe run some kind of AI model on the distributed compute then start getting rid of at least half of them
This is only about 21 amps. Most outlets in a home are 15amps but 20amps isn’t unheard of. From one outlet doubtful but yes one house would provide that much power easily if you split them up to three or 4 rooms on different breakers.
Now it would be fun to watch his electric meter spin like a saw blade … (yes I’m old … I remember meters that had spinning discs)
Just two 15A breakers is enough actually. Outlets are supposed to be able to sustain 80% power, so you should be able to pull 1.44kW from a singly puny Nema 5-15.
Well true but I was assuming the circuits had some things drawing a little power. Flipping on a device and tripping a breaker with 12 machines on it wouldn’t be ideal :)
I have done this before in my upstairs home lab. 3 beefy ESXi machines, some nas storage, and a basic 10gbe switch eats up a lot of a single 15amp circuit. And apparently turning on a TV pushes it over the edge. Luckily the UPS saved my but while a reset the breaker and shut some stuff off.
I have a couple of these (only the G2 and G3 SFF) and they consume between 6-10w when not under load, and they max out at 35w (or 65w depending on CPU). I run proxmox with 64gb ram and they are surprisingly efficient.
Psh 1 plug aint shit. Every Pic I see from anyone who lives out in those ghettos of India, Central America or any spacific islands they also only rock 1 plug but theyre running the corner store, the liquor store, the hospital, their style of little school middle school and old school, 3 hair salons if Latin or 3 nail salons if spasific, Bollywood, every stadium from every country in the world cup, and always 1 dude trying to squeeze 1 more plug in cuz hes runing low bats. Idk why the American ghetto is so pussy. One time i seen a family that fuckin put covers over empty sockets?!? Come on dog thats like wearing a condom jerking off. NGL tho, I get super jelly seeing pictures from those countries thp with their thousands of power lines, phone lines, sidelines, cable lines, borderlines, internet lines… fuck I don’t know much about how my AOL works but those wizards must be streaming some Hella fast Tokyo banddrifts with all them wires.

That part is wrong for India, at least. Here’s a random site with some stats
India, you can expect ~100Mb/s with FTTH and 50Mb/s otherwise. Reliability is even worse.
And Japan has a 300+ Tb/s connection. Your point?
My point is that the average Indian is not doing “Hella fast Tokyo banddrifts” (not sure what banddrift even means, but no).
And yes, a 1Gb/s connection is theoretically available, but how many people are using the ~₹4000/month connection?
Considering how many people tend to just not have Broadband at home, relying just on mobile internet, we can see how things compare with others.
Also, to point to the tread starter, most of the “thousands of” cables that you see on poles in congested areas, are just abandoned cables from older installations which nobody cared to remove.
Also ~100Mb/s is in no way the average speed in an Indian household. It’s usually lower. I also don’t see any specific mentions of india in your link up there to that random site.

That’s less than a kettle, in the UK at least.
Of course I wouldn’t want to be running that all the time, because electric ain’t cheap.

UK here, we could run that from 1 plug.

Rest is right.
India has gigabit fiber
And Japan has a 300+ Tb/s connection. Your point?
My point is that the average Indian is not doing “Hella fast Tokyo banddrifts” (not sure what banddrift even means, but no).

You’re right. It’s not.
I don’t see any either. Guess why. Because it only has the top 10, further emphasising the point that :
I’m not the same dude that was talking about banddrifts and congested poles.
Indian, btw.
