I would but I don't have the room right now and these are definitely too big. Only have a 1U and a 2U.

Student project: self hosted e-commerce site with all the backend needed for a "real" company.

Optiplex has Proxmox installed and runs a whole virtual infrastructure with VLANs. It has a firewall that does IPsec with a friend's house. It hosts multiple LXC and VMs such as web server + reverse proxy that also does waf, monitoring and log collecting tools (grafana, Loki, Prometheus), RDS using Debian XFCE, AD-like services using Univention, bastion with guacamole, SSL vpn with the firewall, backup with Proxmox Backup Server. The Proxmox VE is in cluster with another node on the other side of the IPsec tunnel.

The website is not ready yet, so it's not accessible through the internet.

The NAS runs OpenMediaVault and is directly connected to the optiplex to a second interface, which is passed in a VLAN inside Proxmox so it can communicate with PBS. It is used to store backups of both sites. 4x2TB in RAID 5 (budget forced me not to go with 4x4TB).

The Pi 5 cluster runs Proxmox on top of Raspberry Pi OS Lite and runs various LXC such as my own DNS for my personal lab, Discord bot instances that are meant to wake or suspend a machine in the network using Wake on LAN. It was my first introduction to Proxmox and I used it as an argument to install Proxmox on the optiplex.

Just got my hands on this for my uni society for free off of gumtree, only to realise i have nowhere to put it lol. what's the best way to sell it?

1 media server with 4Tb drive, 3 TV boxes with Linux inside, old 32bit SBC for home assistant and 4 Orange Pi 5 with NVMEs

Sometimes it’s not about what you should do, just what you can do.

I was doing decom on some very old IBM servers at work and I considered possibilities of repurposing the raid controllers and backplanes with something like a thin client (I have some Dell Wyse boxes on hand) this turned out to be expensive to explore and likely slow/ cumbersome. So I settled on doing something cheap and definitely slow!

I have limited experience of software RAID outside of ZFS on Proxmox. I had heard MDADM can create an array out of anything on any interface. This is a Pi 5, with 5 480GB SATA SSDs connected to a single USB port via a powered hub. That hub is also powering the Pi itself! Pushing the limits of daft over here…such are the joys of learning.

I designed the enclosure in Shapr3D and the drive trays are from the old IBMs. I have ordered some plastic fibre so I can get the tray lights working. I only have glass on hand and can’t cut it.

The drives are configured as RAID 5. Performance is actually…serviceable? It will do well replacing my little single disk NAS. I have also connected a Buffalo DAS (RAID 1) via USB; I am making a backup of the USB Array using rsync on a schedule. I am willing to be proven wrong, but I don’t trust this thing yet!

Ultimately I don’t think I would recommend this setup to anyone, but it has been a great learning exercise!

After lurking for a while I decided to give homelabbing a shot and picked up an HP Pro desk G4 8th Gen and set it up to learn ProxMox and Docker. I feel like this could be a slippery slope...

I had been debating if I wanted one or not. Then I found it on a really good sale so I pulled the trigger. Super impressed with the quality. When you opened the box it has all the pieces laid out in foam. It came with two screw drivers, actual screw drivers with a handle. One hex head and one Philips. When I pulled the sides out I noticed how nice the metal was and how well it was cut. It came with an over abundance of screws and nylon washers. Assembly is straight forward, but if you get hung up DeskPi has you covered there as well. The instructions are clear with nice pictures. Overall super impressed with it. Need to get it loaded up.

Ignore the mess in the back. I just got a new desk as well and pulling everything down.

Just finished upgrading my server to ASrock Velocita Z690 64GB DDR5 104TB of MDD Drives Unraid 7 Cable management isn’t the best, but I have new data cables coming in so I wasn’t super worried with how they look for now. Will also be adding 3 140mm BeQuite pure wing fans to the front to push air over the drives. Mainly using it for the usual plex Arr stack with cloudflare tunnel for overseerr but I’m looking into Immich and some other stuff like pihole

Hi everyone, first time presenting my hardware. I built the rack with my girlfriend (she insisted to get credit here and tbf she deserves it too) For the specs :

Switch : • Cisco Nexus N3K-C3064TQ-10GT • 48x RJ-45 1/10Gbps + 4x QSFP+ 40Gbps

NAS (HP DL380p G8 LFF) : • TrueNAS SCALE (IP : 192.168.0.10) • CPU : 2x Xeon E5-2697 v2 • RAM : 378 Go DDR3 • Storage : • 3x 12 To RAIDZ1 • 3x 2 To RAIDZ1 • 2x 240 Go mirror (boot) • 2x 1 To mirror (app locale)

Proxmox servers : • PVE1 (IP : 192.168.0.11) • CPU : i9-9900KF • RAM : 32 Go • Disks : 3x 240 Go RAIDZ1 • GPU : Intel ARC A380

• PVE2 (IP : 192.168.0.12) • CPU : i9-13900K • RAM : 78 Go • Disks : 3x 1 To SSD RAIDZ1 • GPU : GeForce GTX 960 

Everything is connected in 10Gbps and it’s working flawlessly! Very happy with it atm. A little bit power hungry but i still love it !

I mostly use jellyfin and all the arr apps for all my linux ISOs, nextcloud, pterodactyl (cs2 servers for me and my friends), crafty (for some minecraft servers for my friends) and finally some VMs for my business and soon the business of my best friend)

Also i have some trouble to correctly rack my HP DL380p LFF (it doesn’t go all the way in) i tried to switch the rails but still no luck :/ If someone as an idea i take it !

Except the Synology

This is my first OPNsense setup with a m920q with a 4 2.5gbit nic. And a FX-3100 for 5G wan. Took too long to get working at full speed because the FX-3100 in IP passthrough mode wont give out the Public IP to another device unless DHCP is on but its a option that is greyed out when IP passthrough is on so didn't think turning it on would make a difference so i tried a lot of other things first. Without passthrough and dubbel NAT I had around 180 Mbps down and 40 Mbps upp. With it getting the IP directly it gets 700-800 Mbps down and around 80-100 Mbps up. Now just waiting for a unifi USW-8-Lite POE so i have a managed switch to work with.

Been my multipurpose but mainly BOINC/backup server for years. Eventually want to rack mount it and the other build that's being used as a game server host.

I have always had this thought that I couldn’t get out of my mind that smart phones can be the best travel router. They have excellent cell reception and have wifi hotspot and basic routing capability. It can even use WIFI as WAN connection for wifi hotspot clients. And to further to add, we have those sharing apps which allows file share wirelessly.

Upon researching, i got to know that this not recommend. Poor Wifi performance, battery degradation and Phone Wifi Hotspot not being featureful seemed to be top negative points that people mentoned.

But I have always wanted to try it out. My requirements were simple:

1. Stable connectivity of wifi.
2. Have multiple options of WAN like 5G, Wired, and over wifi.
3. Devices in the network are able to able to connect my home services over Tailscale or Wire guard VPN.
4. Maybe, when in a good network.
5. A secure file share using USB/ microsd card to share Movies/ TV Shows and sometime to do a temp backup of Photos or Files.

After my father got a new Phone and this phone was not it use, my mind went down the pit to finally use this for mentioned purposes of a travel router.

This is an old not in use Samsung S20 Fe with 5G capabilities. I was able to root and factory reset this. Then
Install FDroid or Droidfy app marketplace. Then Install following:

1. VPNHotspot: Share VPN to wifi hotspot clients. This also adds static IP for the device where wifi hotspot is enabled.
2. Prim-ftpd: Create SFTP share of attached memory card or even USB. This app is great. You can chose the network interface to isolate this sftp serve.
3. Wireguard/ Tailscale: Connect to homelab. (If possible, I recommend Wireguard for little better performance).

Using these apps to achieve the above mentioned functionality is self explanatory once you install it. Using 5ghz wifi hotspot is highly recommended.

I have been using this for last week. Has been very stable with attached power bank. Surprised that this does work.

Issues:

1. The only issue that I faced was that phone needs to plugged in all the time. (Hence, the attached power bank). This shouldn't be dealbreaker since phones nowadays have a charge limiter feature which can limit to charing to 80%. And this is a travel router. Not a permanent solution.

Regarding perfomance:
I see a WAN speed of 100 mbps max on a device using the Wifi Hotspot. On LAN side, I can see a max speed of 200 mbps over two devices connected to mobile hotspot. (My mac and iphone). I have no issues playing movies (bitrate: 5-10 mbps) shared over SFTP.

Improvements:

1. Use this with a type c hub with charge passthrough and ethernet port to enable wired WAN. and even share USB drives. This also gives an additional feature to use with TVs if your hub has HDMI and phone support desktop mode like Samsung DeX.

   Concerns:

2. I am not very sure about the security provided by this solution. Can someone access LAN from the WAN side. Are rooted android phones safe enough for this.

3. Microsd card prices for 1 TB and higher storage.

What do you guys think about this. Any comments on my concerns or issues I should be aware of in future?
