Proxmox CLUSTER. What is it and why? Creating a cluster of 3 Nodes. Proxmox Cluster is a combination of several servers running Proxmox VE into a single management system. This is necessary to increase fault tolerance, distribute the load and ensure continuous operation of virtual machines. The cluster allows you to manage all servers from a single interface, easily transfer virtual machines between nodes and automatically switch them in the event of a failure of one of the servers. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I would be very grateful for support in the form of a cup ☕️: https://www.buymeacoffee.com/RomNero ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Write your suggestions to: [email protected] Matrix: @romnero:matrix.romnero.de ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 Proxmox as a separate server 01:04 Why proxmox cluster.
