Pv, don't buy an RPi please, buy an old PC/laptop for a node. RPi sucks

Vikingo 2y ago

My rpi has been running 24/7 for like 4 years lol it’s been great

Yah but do you run channel rebalancers or run anything cooler off the node like Plex or nextcloud?

You can pay $200 to get a node only on rpi or you can pay $100 for an old PC and have a whole dang server!

Ok. You’ve said this multiple times. Can you explain exactly what your problem is with an RPi if I’m not running anything super compute intensive?

Now you don't have the option to run something intensive.

When for the same price you could have had a relay + node + media server in one.

Sure, if I want to run something heavy I’ll upgrade, but if it fits my compute power needs would you still have a problem with it?

Why "upgrade" when you could have paid less for a better PC? This is my issue with RPi. Usually upgrades are more expensive.

Jonathan 2y ago

Fair enough. So your basic point is that I should just buy more computer than I need in case I want to run something else because it’ll be easier to buy too much than upgrade and migrate.

Yes basically. I started with RPi too, everyone on twitter had them and a cool case. But it wasn't even enough power to run a mid level lightning node that balanced channels once every 5 minutes.

Speaking from experience here! I'm mad that bitcoiners all recommended it and it's a piece of shit 🧡

😂

Later this month I have to move a cluster I built from 36 tower PC’s and 100’s of meters of infiniband.

It’s amazing what you can do with a pallet of refurb. 😉

Infiniband sounds like Cisco

Mellanox

The cables cost more than the PC’s.

I needed to build a memory fabric and lots of sockets+infiniband was the most scalable way to do it.

Mellanox, crazy expensive cables, infiniband, so Cisco

Actually technically Mellanox was acquired by NVIDIA..

ever since nvidia acquired them

I seem to recall it was pretty expensive tech even before NVIDIA acquired them. I’m sure NVIDIA cranked up the price.

Yeah, cables are $1000s…

Interesting, I have ~100x of these lying around.

100x Mellanox cables? Basically used to connect and train supercomputers? Yeah, pretty sure they are holding value better than the dollar.

Yep, I have probably 500m - 1km of this stuff.

80 GB/s plus all the network cards and two switches.

When did they get that expensive? Bought some for maybe 200 a few years ago

I’ve seen them for $500-$1000 new from Mellanox

nym 2y ago

Same

I just remember we had to expense like 10 and it was many thousands of dollars, had to get special approvals..

Depends on the cable

Roir Raw 2y ago

Okay my cables were 100Gb/s, no splitter and definitely not 4m

Still, that’s a ridiculous price for a cable.

Roir Raw 2y ago

Just like the $65k switch

Good to hear your perspective. I think RPi gained traction because it was easy to setup with Umbrel with little knowledge/skills. For me, I have no idea what to do with Ubuntu or Debian on a small PC - drivers etc

Thank you! I need to reduce the price and size, that's the reason... But any recommendation from you maybe make me change the choice
