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.

THIS TRAINING COURSE WILL HELP YOU:

  • Understand the architecture of Proxmox cluster and the functioning of key components (pmxcfs, Corosync)
  • Master the deployment and management of Ceph cluster for robust and scalable storage
  • Correctly configure high availability (HA) and prepare for outages and disaster recovery scenarios
  • Automate tasks using REST API or command line
  • Gain an overview of asynchronous replication, advantages and pitfalls of various strategies

WHO SHOULD ATTEND?

  • System administrators and IT specialists who already have experience with basic Proxmox VE management
  • Architects and DevOps engineers planning to deploy a cluster or transition to HCI
  • Administrators responsible for HA operation, backup, disaster recovery, or virtualization management automation
