Mastering Proxmox - Third Edition

By: Wasim Ahmed

Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

Preface

Liquid cooling


In this solution, computer equipment is cooled using liquid, as liquid is 1,000 times better at heat transfer than air. We can effectively remove heat directly from IT equipment and transfer it with great ease out of the facility. Liquid cooling takes away the hassle of running a large HVAC system, thus saving enormous costs and reducing noise significantly. Liquid cooling requires no internal fans, thus we can increase server density per rack tenfold. Liquid cooling is the future, as more and more IT facilities are realizing its full potential. By using liquid cooling, we can also decrease our energy consumption, reducing our carbon footprint enormously. There are different liquid cooling solutions available on the market.

Total immersion in oil

IT equipment is totally submerged in mineral oil. Hot oil is pumped through a liquid-to-liquid heat exchanger, where the heat is carried away, using water, to an outside cooling tower. Water and oil never have full contact, only heat...
