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.
The console is laggish. I have just setup a Windows 2022 server 2 CPUs with 2 cores and 32GB of RAM
I’ve used the diskspd utility to do some benchmarks
-t4 - o32 -b4k -r4k -d120 -Sh -D -L -c5G
I’ve done tests by incrementing the -w parameter by 25 starting at 0
The results are as follow w0 CPU AVG 92.66% TOTAL READ IO/S 11649.49 AVG LAT 10.97
w25 CPU AVG 3.26% TOTAL READ IO/S 214.61 AVG LAT 425.091 WRITE IO/S 71.72 AVG LAT 522.129

The proxmox host has 2 ST600MM006 HDD (10K RPM) configured in Raid0 with a PercH710
