Client environment: Technology company with manufacturing · approximately 800 employees · Erfurter Kreuz industrial area
Starting point #
The client used VMware as its virtualisation platform and wanted to supplement the environment with a compact two-node Proxmox system using ZFS storage.
The objective was active-passive operation: if one node failed, the second machine should be able to take over with a short interruption.
My contribution #
- Installed and configured two Proxmox VE nodes on x86-64 hardware.
- Set up local ZFS storage and automatic replication between the nodes.
- Established the technical foundation for resuming operations on the surviving node.
- Hardened both systems against unauthorised access.
Technical approach #
Data is replicated between the two nodes’ local ZFS storage systems, providing a replicated recovery point on the second node.
Replication is asynchronous, so the available recovery point depends on the last successful replication. Data replication and takeover orchestration are separate functions: replication alone does not provide automatic failover.
Technologies: Proxmox VE, ZFS, x86-64 servers, storage replication.
Outcome #
A two-node Proxmox environment with active-passive operation and automatic data replication. If one node fails, operations can resume on the second machine with a short interruption.
