This document discusses clustering, high availability (HA), and software-defined networking (SDN) using Proxmox. It provides steps for breaking a Proxmox cluster and removing nodes. It also covers configuring HA using ZFS and Ceph storage pools, monitoring Ceph, and using Open vSwitch for SDN. The document proposes an SDN architecture with Proxmox involving core, inside, and EVPN zones connected via VXLAN and VLAN networks.
