Configuring a network for a Proxmox VE cluster

We have mentioned that a network with redundancy is needed for a HA environment. As most of our services are based on networks, avoiding network failure is an important task for us. So how can we build that?

Building a network with redundancy

Since there is a lot of internal traffic including health check messages, data transferring from/to a shared storage, and SNMP messages, a high-speed network that allows a gigabit Ethernet connection is recommended.

For our testing environment, we used two Cisco Catalyst 2950 switches that have 24 Fast Ethernet ports each operating at 100 Mb/s. These switches are interconnected to ensure there is no single point of failure. Since multiple fencing methods will be demonstrated, an SNMP server will be configured for the network switches too.

Building a separate network for the Proxmox VE cluster

In Chapter 1, Basic Concepts of a Proxmox Virtual Environment, we successfully created our own VMs using the default...
