Selfhosted

3x Intel NUC 6th gen i5 (2 cores) 32gb RAM. Proxmox cluster with ceph.

I just ignored the limitation and tried with a single sodim of 32gb once (out of a laptop) and it worked fine, but just backed to 2x16gb dimms since the limit was still 2core of CPU. Lol.

Running that cluster 7 or so years now since I bought them new.

I suggest only running off shit tier since three nodes gives redundancy and enough performance. I've run entire proof of concepts for clients off them. Dual domain controllers and FC Rd gateway broker session hosts fxlogic etc. Back when Ms only just bought that tech. Meanwhile my home "ARR" just plugs on in docker containers. Even my opnsense router is virtual running on them. Just get a proper managed switch and take in the internet onto a vlan into the guest vm on a separate virtual NIC.

Point is, it's still capable today.

I'm self-hosting in a 500GB HDD, 2 cores AMD A6, 8GB RAM thinkcentre (access for LAN only) that I got very cheap.

It could be better, I'm going to buy a new computer for personal use and I'm the only one in my family who uses the hosted services, so upgrades will come later 😴

Oldest I got is limited to 16GB (excluding rPis). My main desktop is limited to 32GB which is annoying, because I sometimes need more. But, I have a home server with 128GB of RAM that I can use when it's not doing other stuff. I once needed more than 128GB of RAM (to run optimizations on a large ONNX model, iirc), so had to spin up an EC2 instance with 512GB of RAM.

your hardware ain't shit until it's a first gen core2duo in a random Dell office PC and 2gb of memory that you specifically only use just because it's a cheaper way to get x86 when you can't use your raspberry pi.

Also they lie most of the time and it may technically run fine on more memory, especially if it's older when dimm capacities were a lot lower than they can be now. It just won't be "supported".

Wow, it's been a long time since I had hardware that awful.

My old NAS was a Phenom II x4 from 2009, and I only retired it a year and a half ago when I upgraded my PC. But I put 8GB RAM into that since it was a 64-bit processor (could've put up to 32GB I think, since it had 4 DDR3 slots). My NAS currently runs a Ryzen 1700, but I still have that old Phenom in the closet in case that Ryzen dies, but I prefer the newer HW because it's lower power.

That said, I once built a web server on an Arduino which also supported websockets (max 4 connections). That was more of a POC than anything though.

My home Kubernetes cluster started out on a Core i7-920 with 8 GB of memory.

Upgraded to 16 GB memory

Upgraded to a Core i5-2400S

Upgraded to a Core i7-3770

Upgraded to 32 GB memory

Recently Upgraded to a Core i5-7600K

I think I'll stay with that for rather long...

I did however add 2 Intel NUCs (gen 6 and gen 8) to the cluster to have a distributed control plane and some distributed storage.

Yep, mspencer dot net (what little of it is currently up, I suck at ops stuff) is 2012-vintage hardware, four boxes totaling 704 GB RAM, 8x10TB SAS disks, and a still-unused LTO-3 tape drive. I’ll upgrade further when I finally figure out how to make proper use of what I already have. Until then it’s all a fancy heated cat tree, more or less.

I met someone that was throwing out old memory modules. Literally boxes full of DDR, DDR2 modules. I got quite excited, hoping to upgrade my server’s memory. Yeah, DDR2 only goes up to 2GiB. So I am stuck with 2×2GiB. But I am only using 85% of that anyways, so it’s fine.

You can do quite a bit with 4GB RAM. A lot of people use VPSes with 4GB (or less) RAM for web hosting, small database servers, backups, etc. Big providers like DigitalOcean tend to have 1GB RAM in their lowest plans.

People in this thread have very interesting ideas of what "shit hardware" is

I used to self host some stuff on an old 2011 iMac. Worked fine, actually

I've got a i3-10100, 16gb ram, and an unused gtx 960. It's terrible but its amazing at the same time. I built it as a gaming pc then quit gaming.

Aw yep, bought an old HP pro-lient something something with 2 old-ass intel xeons and 64GB ram for practically nothing. Thing's been great. It's a bit loud but runs anything I throw at it.

I'm hosting a minio cluster on my brother-in-law's old gaming computer he spent $5k on in 2012 and 3 five year old mini-pcs with 1tb external drives plugged into them. Works fine.

Why didn't you post this before I bought the RAM?!

My i5 6600k will turn 10 years old this year. I'm fortunate because upgrading to 32 GB should keep it running for a while still.

7 websites, Jellyfin for 6 people, Nextcloud, CRM for work, email server for 3 domains, NAS, and probably some stuff I've forgotten on a $4 computer from a tiny thrift store in BFE Kansas. I'd love to upgrade, but I'm always just filled with joy whenever I think of that little guy just chugging along.

Me on a RPi4.

I'm sure a lot of people's self hosting journey started on junk hardware... "try it out", followed by "oh this is cool" followed by "omg I could do this, that and that" followed by dumping that hand-me-down garbage hardware you were using for something new and shiny specifically for the server.

My unRAID journey was this exactly. I now have a 12 hot/swap bay rack mounted case, with a Ryzan 9 multi core, ECC ram, but it started out with my 'old' PC with a few old/small HDDs

What hardware are you using where the cpu says you are limited to 4gb?

Even a 25 year old Pentium 4 supports 8GB.

Got all my docker containers on an i3-4130T. It's fine.

4 gigs of RAM is enough to host many singular projects - your own backup server or VPN for instance. It's only if you want to do many things simultaneously that things get slow.
