Mastering Proxmox - Third Edition

Simplicity

Simplicity is often overlooked in a network environment. A lot of times, it just happens naturally. If we are not mindful about simplicity, we can very quickly make a network unnecessarily complex. By mixing hardware RAID with software RAID, putting RAID within another RAID, or through multi-drive setup to protect OS, we can cause a cluster's performance to drop to an almost unusable or unstable state. Both Proxmox and Ceph can run on high-grade commodity hardware, as well as common server hardware. For example, just by selecting desktop-class i7 over server-class Xeon, we can slash costs in half while providing a very stable and simple cluster setup, unless the task specifically calls for a multi-Xeon setup.
