Virtual Data Center - Site Manager for Proxmox VE 8.x with Ceph Cluster

This tool is designed to synchronize and replicate data between two Proxmox VE clusters using Ceph in an incremental, differential manner.

Key Features

Cluster Setup:
- Supports a primary data center (DC) cluster with 6 nodes using Ceph for replication or erasure coding as storage.
- A similar setup is used for the far Disaster Recovery (DR) site, with 6 nodes using Ceph replication or erasure coding.
VM Synchronization:
- Allows virtual machines (VMs) to be synchronized from the DC cluster to the DR cluster over a secure, dedicated line or VPN.
- Utilizes Ceph's RBD export with snapshots for backend data handling.
- Supports synchronization based on resource groups, enabling efficient management of multiple VMs.
- Syncing can be scheduled to automate the process, ensuring regular updates without manual intervention.
- VMs remain visible and active on one cluster at a time, though the drive image is maintained on the other cluster for differential snapshot restoration.
Disaster Recovery (DR) Readiness:
- Uses VxLAN to facilitate seamless DR drills, enabling quick switching between the DC and DR locations.
- Supports smooth transitions back from the DR site to the DC site after testing.
Scalability:
- Scale till 1000 VMs in a cluster.
- Successfully tested with 10+ VMs and a 5TB storage environment.
Management Interface:
- Webmin is used as the frontend for managing the synchronization, with resource group-based controls to handle multiple VMs.
Additional Features:
- Supports export of the VM inventory list for easy tracking and reporting.
