There are no one-setup-fits-all solutions when it comes to a server node setup. The components described in this chapter are mere examples of the possible setups. However, this should provide you with a baseline to direct your thinking when choosing components for the cluster environment you are responsible for. We hope this will aid you in your quest to find that perfect balance between performance and budget that all network administrators crave for.

In the next chapter, we are going to see some real incidental-based issues and how to troubleshoot a Proxmox cluster environment. These issues have been taken from day-to-day running clusters in production scenarios.
