I currently have a 2 node proxmox cluster composed of PowerEdge R620
Node 1 has 2 x E5-2670 CPU and 128GB of RAM Node 2 has 2 x E5-2660 CPU and 128GB of RAM
I am and want to use these to host some Win2022 DC as well as some Ubuntu containers and servers (pihole, Zabbix, *arr). I also want to spin up VMs and/or containers to test new solutions and perfect my knowledge.
Should I upgrade the CPUs to 2690v2, 2695v2 or 2697v2 or should I look at other options to improve performances.
Electricity cost for running the servers is a non issue.
Those cpus are more than fine for anything you’d might throw at them. That said - if you get an upgrade for cheap, why not? But nothing I’d say it might be worth hundreds of dollars for forced upgrades.
