Bare Metal Hypervisor Recommendation

[Niklas]

Hello everyone, I am curious as to what you guys use for bare metal orchestration. I know for VPS's we use proxmox, but wanted to know what you guys use or a recommendation for bare metal servers. Essentially, we would need it to manage ISO's for installation, IP assignment, and integration with billing (looking at using WHMCS since we already have a license). We would need the software to expand with the number of servers as they become available and occupy additional rack space.

What do you use? What do you recommend?

Thank you in advance!
