Proxmox VE HA Cluster
- Building a highly available (HA) cluster based on Proxmox VE
- Three-node cluster with HBA-based multipath management on redundant FC storage
- Ensuring system continuity and minimizing service interruptions
Proxmox VE: HA Clusters, Ceph, Backup and Training
Proxmox VE (KVM) is the platform I work with most. In production environments I have built and operated HA clusters, Ceph-based distributed storage, scheduled backups with Proxmox Backup Server, and disaster recovery scenarios.
I have migrated VMware ESXi and XenServer environments to Proxmox. In 2025 I turned that experience into a hands-on Proxmox VE course on Udemy and a series of LinkedIn articles.
