Really weird. Might be a bug.
I can't find anyone else reporting memory usage problems. Maybe you could ask in the support community and see if anyone else has encountered the same problem.
Your VPS should be more than enough and you shouldn't have to spend more money because of a software issue.
I see, thanks for the explanation.
If I understand correctly, with a service like Tailscale that doesn't require Dynamic DNS even if your IP changes, there wouldn't be a risk of revealing the IP, right?
That's strange, from what I've read a VPS like that should be able to handle at least 20 concurrent users.
Are you running anything else on the VPS?
I've personally used Proxmox in the past because it's easy to use, and it served pretty well for what I wanted to do (simple services like Headscale, Bitwarden, etc).
But I'm kind of a noob so you should probably ask more people.
It looks like [email protected] is more active and has become the "replacement" for r/selfhosted.
If you post there you'll probably get more helpful answers.
I thought that solution completely ideas the homelab IP. Why/How is it visible?
Immich is a very promising app.
Right now it's probably the most ambitious in terms of functionality, and a lot of people recommend it as an alternative to Google Photos.
However since it's still in Beta, if you use it, be sure to have a backup of those photos somewhere else. Just in case.
There may be some sort of marking that indicates if the bay is only accepts Nvme drives on the front of the drive tray. Line this.
Another option would be to open the server and find the part number for the backplane on Google or Dell's page.
U.2 connectors and sata connectors are pretty similar, so It will be hard to tell only by watching the connector.
The link you've provided is the type of enclosure I've mentioned, that goes from m.2 to u.2 . I've never used one of those before, so I don't know how well they work, but there could be compatibility issues with some operating systems, especially if you plan on setting up RAID.
If the backplane ends up having SAS connectors, you could try and get used enterprise SAS SSDs. Sometimes they can be had for about the same price as consumer SATA SSDs. And the max sequential speed is 1.2 GB/s.
The first thing that you should do is see if your server supports Nvme drives and which bays do. If I'm not mistaken not all R640 have bays that support Nvme.
If it supports Nvme drives then it has a backplane with U.2 connectors. Both U.2 and U.3 drives are compatible. These type of drives are enterprise only, and unless something has changed recently, consumer grade 2.5" Nvme SSDs don't exist.
New enterprise SSDs are very expensive (used are hard to find) and they're only worth it if you're going to write a lot to the disk.
Apparently there are m.2 to u.2 enclosures, which would allow you to use cheaper consumer drives. I've never used them, so I don't know how good they're. They may be total crap, so do your research before you buy such an enclosure.
The last option is to buy consumer grade Sara SSDs. This is the cheapest by far right now and probably the best idea unless you know you need faster drives. Sequential speeds of almost 600MB/s. Compatible with Sata/SAS ports, but not with u.2 ports.
For drives up to 4TB I'd recommend TLC and if you want 8TB drives I'm pretty sure there's only QLC.
Some cat 5e cables are able to do up to 10gbps for short distances (less than 30 meters).
2.5gbps and even 5gbps should be achievable for most cat 5e cables.
Your cat 5 cables could be a bottleneck depending on their quality. If they are high quality they should be able to achieve 1gbps over short distances (30-35 meters).
However your router only has 1gbps so it doesn't make sense to upgrade your cables unless you also upgrade your router (and presumably your network cards).
If you decide to upgrade your networking I'd recommend that you buy cat 6a cables.
Cat 7 is only a standard recognized by ISO if I'm not mistaken so finding good cables is harder.
And cat 8 is the newest standard recognized by both ISO and IEEE, but it's too expensive for home users.
Compartmentalization.
Get another drive for your PC (an SSD is a better idea for gaming especially since now they're pretty cheap).
Install Windows if you want more compatible games or Linux if the games you're going to play are compatible.
Encrypt both drives and don't log in into anything important while on your gaming drive.
Try to buy all of your games on GOG or itch.io (or similar platforms where games don't have DRM).
Use different usernames between each game and/or between games that you play with strangers and your friends. Don't use usernames that you're already using, especially usernames that could link to your real identity.
Avoid games with invasive anticheats like Valorant.
People live to shit on the official app but in terms of UI and functionality is good.
It's far from perfect, but it is very usable.
Got It! Thank you very much.
