Standing Up Dell Power Edge R820

I was able to get my hands on this powerful Dell Power Edge R820. I have another Dell Power Edge, but this one is by far more powerful. I installed Proxmox on this device and configured iDrac for it as well with static IP addresses and raid configuration. The IP addresses are outside the DHCP scope and are set on my main network. Below is the current resource availability. LOTS OF POWER HERE!

I installed Proxmox version 8.2.2 on this from an old boot drive. They are currently at version 9.1, which I plan to upgrade down the road. I look forward to jumping that hurdle.

Plans for this Dell Power Edge are setting up a domain controller, file server, Hyper-V, and configuring a firewall on it as well. Additionally, DHCP and DNS server to it as well. I will either use pfSense or OPNsense (probably pfSense).

Currently my UDM Pro Max is my firewall, DHCP, DNS server, etc. which is running everything. Unifi is great and I like the interface and usability, but I want to expand my knowledge and familiarity with other firewalls. I regularly use Sophos at work and have a strong handle on that vendor. However, I want to expand my knowledge, familiarity, and skills on other firewalls.
