all three 'pmx' hosts are running Proxmox VE - I've grown to love Proxmox very much over my last two years with it.
pmx1 - 4th Gen Intel Lenovo ThinkCentre
This host is where I perform tests of HA to my other Proxmox hosts, run very light weight Proxmox containers, which includes this website! -- a secondary domain controller, and my HomeAssistant instance.
16gb RAM / 2tb SSD storage / 4th gen Intel i5 / single 1gb link
pmx2 - 10th Gen Intel Dell Precision Workstation
This host accounts for the bulk of my storage, and hosts my personal media collection. It is where I test media encoding, optimized delivery, service prioritization, and occasionally, local AI models.
256gb RAM / 8x 14tb spinning drives in RAID 6 and a single 2tb SSD for cache and operating systems / 10th gen Intel i9 / dual 10gb SFP+ link / nVidia Quadro RTX 6000
This is the compute powerhouse for my lab, I host nearly everything on this single host with HA configured to pmx2 and pmx1 for critical VMs.
This host runs my primary domain controller, my Docker test environment, my Docker production environment, my Nextcloud instance, assorted Windows VMs for testing, Veeam, a service called Pterodactyl that allows node-ready, containerized game servers with a unified management GUI for my and my friends to use, and a VM that handles PxE booting for distributing custom images inside my home network.
In addition to that, I lease compute space / basic webhosting from this host to friends and family who are students and don't have the necessity or means to setup a similar environment themselves.
512gb RAM / 4x 14tb spinning drives in RAID 5, and 3x 2tb SSDs in RAID 5 for boot disks + fast storage when needed / quad 10gb SFP+ link / nVidia Quadro RTX 6000
theEveryBox - Dell Poweredge R710
The purpose, and contents of this host change rapidly, so I will just list some of its 'past-lives' so to speak.
An ESXi host for testing a project involving VMs sharing a single GPU for a thin-client LAN party I hosted - this was really silly and really fun.
A Hyper-V host for when I was working at a company that exclusively used Hyper-V and I had not ever touched it before. I built a replica environment on this server so I could press any button I wanted to without disturbing their production environment.
Several different NAS operating systems, benchmarking performance, different drive configurations, and management.
Custom NAS - salvage hardware from an old gaming PC, running TrueNAS
8x 8tb drives in RAID 6 for cold storage and backups, this is the primary target for my Veeam backups.
Synology NAS (off site, out of state) - DS920+
4x8tb drives in RAID 0 this is my secondary backup target for my Veeam instance -- I have a backup copy job that copies my daily backups to this NAS from my on-site backup target.
