Installation Advice

[CauseFX]

Hey everyone.

I currently have 2 servers:
Dell R620 SFF:
running ESXI 6
H710 Mini card
10GBe card
hosting about 20 VM's

Custom build 4U 36 bay Server
running FreeNAS
LSI HBA in IT mode
10GBe card
zfs HDD Storage in RAID10 config
zfs SSD Storage in RAID10 config

I want to migrate away from VMWare (yearly fees) and possibly goto Proxmox.

Questions are:
should I migrate both servers to Proxmox?
Just the Dell server?
Are there advantages from switching from FreeNAS to Prox?

Edit: here are my feature flags from FreeNAS
[root@freenas ~]# zpool get all Media | grep feature

I'm sure I will have more questions, anyway, thank you in advance.

Proxmox VE is a datacenter-grade virtualization platform, FreeNAS is a datacenter-grade storage appliance/platform, so it's pretty different. You can install all the commandline daemons that FreeNAS uses (or at least similar ones) on Proxmox VE, yet there is no GUI for that and strictly speaking this is part of the underlying Debian, not Proxmox VE itself. It is work and it does not have any benefits besides having PVE on that node as well and all the manual work you have to put it. I'd stick with the working FreeNAS environment and "just" use PVE on the dell servers.

Keep in mind:
For working HA in a Cluster with PVE and a shared storage, 3 nodes are required for quorum purposes.

I did not know this. good to know... I do have another Dell R420 but dont feel like hooking that up just for HA since nothing is MC.

Thank you for the insight and advice.

What do you mean by MC? I'm unfamiliar with this abbreviation.

In practice, a raspberry pi can be used as a quorum token for 2 node cluster:

MC as is Mission Critical.I do have a few Pi's laying around i can use.
