In this chapter, we have covered an important feature named Proxmox High Availability. It is a feature that gives control to Proxmox nodes to automigrate virtual machines during a node failure or maintenance. We also saw how this feature actually works and what are the steps involved in setting it up. We learned about new equipment called managed PDU, which allows an administrator to power up or power down an equipment remotely. We also configured one of our virtual machines to take advantage of High Availability.
In the next chapter, we are going to look at an enterprise-class distributed storage system named Ceph, and set up a Ceph cluster to work with Proxmox. We will go through a step-by-step process of the Ceph configuration and have a deeper understanding of why an administrator should use Ceph and how it works.
