I got a used Dell R720 with dual Xeon CPUs, 128GB of RAM and 2x 146GB, 2x 300GB and 2x600GB SAS hard disks.
I would like to use this as my VM server in my lab. Primarily I need it to run the Unifi controller, but I’d like to add som other VMs later on.
I’d like to put the disks in Mirror and use the 146 disk to install the hypervisor, 300 disk to install VMs on and the 600 disk would be a local file share.
So do you have any recommendations what hypervisor to use? As it’s a lab it has to be free, so maybe proxmox, xcp-ng or maybe ESXi?
What do you think is best and easiest to maintain.
