minimum hardware requirements for a Proxmox VE 3-node cluster

[maneshvm]

I would like to know the minimum hardware requirements for a Proxmox VE 3-node cluster with HA Ceph storage. We need to set it up in our local environment for testing.

Hello,

Cluster requirements can be found at [1], system requirements can be found at [2]. There are special considerations for HA that are listed at [3].

FWIW our proof of concept lab install was some retired/replaced PCs with a few old hard drives added. It’s really quite flexible.

I know you said testing but you might read through https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/.

Adding to the already posted links the Ceph chapter of the manual is worth a read especially this section:
