8 server and so what?

[Gilberto Ferreira]

Hi folks
I have 8 server.
What would you do?

1 - all of them with Ceph and vms
Or
2 - 5 nodes to Promox Ceph cluster and 3 server for vms?


I'll wait for your thoughts and suggestions.

this depends on your hardware / infrastructure. What kind of storage, what kind of nics / switches etc.

All servers
2x 480gb NVME
4x 3.7 TB NVME
2x 1gb nic
4x 10gb nic

What's in the servers? Can you e.g. combine those 8 to get 4 faster ones?
Does the electricity bill concern your?
Do they have proper hardware support or would it be best to have one of the 8 as spare?

I run a 10GbE Ceph in production. Since Ceph is a scale-out solution, I would make a 7-node Ceph cluster and use the other server as a bare-metal Proxmox Backup Server or use it a replacement server if other nodes fails.

Just make sure all hardware is the same (RAM, CPU, NIC, Storage, firmware, etc).

I just thought that separating the storage from the nodes where the VM will run would be a good practice. Just an idea!

It is but I do have experience managing proprietary hyper-converged infrastructure (HCI) platforms at work like VMware vSAN and Nutanix AHV. I'm also involved with another project at work in which they are migrating to Hyper-V HCI.

Can't beat Proxmox & Ceph as a HCI platform.
