Proxmox VE – Advanced Management and High Availability (PROX2)

Virtualization, Proxmox

The Advanced Proxmox VE Management course is designed for administrators who have mastered basic management and wish to advance to a higher level. We will focus on advanced topics such as building multi-node clusters, deploying distributed Ceph storage, high availability (HA) solutions, data replication, automation, and backup using Proxmox Backup Server.

Each topic is supported by practical hands-on exercises where participants will try out the configuration of real scenarios including failures, recovery, and performance tuning. The course will help participants effectively design and manage a robust virtualization infrastructure for operation in a production environment.

    3. Basics of SDN in Proxmox: zones, vnets, bridges
  • Storage management – advanced options
    1. Shared storage backends (NFS, iSCSI, ZFS over iSCSI, Ceph)
    2. Examples of storage deployment in clusters
    3. Storage redundancy and failover
  • Deployment of Ceph in Proxmox environment
    1. Hyper-converged infrastructure (HCI) – architecture and benefits
    2. Ceph RBD for storing host disks
    3. CephFS for shared file system between hosts
    4. Management, maintenance, and best practices for Ceph cluster
