I would like to ask a question that I am having. I have the following scenario, 6 HP Proliant DL360/380 G7 servers that I am wanting to create a Proxmox + Ceph cluster. All these servers have the same configurations: 2x Xeon E5630 Quad Core CPU, 48GB RAM, 4x 480GB SSD (connected using LSI SAS 9211-8i non-raid) and dual 10GBE SFP+ network card. I understand virtualization well (today these servers are with ESXi), but very little about SDS (ZFS, Ceph, etc.). Researching Proxmox + Ceph I found that I have two scenarios for my future architecture:
Scenario A: use all 6 servers with Proxmox + Ceph and create an SDS with 4 OSDs per each server using all 6 servers.
Scenario B: use 3 servers with Proxmox + Ceph and create an SDS with 4 OSDs per each server using the 3 servers AND use 3 servers with only Proxmox to host my VMs.
My environment: 15-20 VMs between W7, W10/11, Windows Server and Linux. My VMs use 4/8/16GB of RAM and they all have a 100GB virtual disk. All 10GBE boards have two SFP+ ports, but today I only use one exclusive one for VMs. The servers have 4 integrated 1GB NICs that I use for management and vMotion (ESXi).
1) What would be the best scenario A or B? Why?
2) How many Ceph monitors should I install in scenarios A or B?
p.s. I know the servers are old but they serve the purpose perfectly, I'm just looking to use Proxmox as ESXi no longer supports these servers.
Live long and prosper,
