Infrastructure Transformation

From Legacy Infrastructure to a Resilient Private Cloud

A 4-node Proxmox VE high-availability cluster with Ceph distributed storage, 40G networking and automated backups—designed and deployed for an ISP in Tamil Nadu.

Industry Internet Service Provider
Location Tamil Nadu, India
Environment 4-Node Proxmox VE Cluster
Storage Ceph Distributed Storage
Engagement Architecture + Deployment
The Challenge

Infrastructure without the resilience required for growth.

The existing infrastructure had limited scalability and lacked the redundancy required for a growing service environment. There was no high-availability platform to minimise the impact of host failures, and no centralised, automated backup platform for reliable virtual machine recovery.

Key Risk Areas

Single points of failure, limited scalability, fragmented VM management and difficult recovery in the event of data loss or infrastructure failure.

The Solution

A modern Proxmox + Ceph private cloud platform.

OpenInfra Systems planned the architecture and deployed an integrated virtualisation, software-defined storage, high-speed networking and backup solution.

  • 01
    4-Node Proxmox VE Cluster A centralised virtualisation platform designed for scalable VM and container workloads.
  • 02
    Ceph Distributed Storage (SDS) Distributed storage integrated with the cluster to improve resilience and provide shared storage for workloads.
  • 03
    40 Gigabit High-Speed Networking High-bandwidth connectivity designed to support storage communication and cluster operations.
  • 04
    High Availability Configuration Cluster-level availability designed to reduce service disruption during individual node failures.
  • 05
    Automated Proxmox Backup Server Centralised and automated backup workflows to simplify backup management and VM restoration.
Solution Architecture

Four integrated layers. One resilient platform.

The deployment combined compute, distributed storage, high-speed networking and backup infrastructure into a centralised platform for virtual machine and container workloads.

LAYER 01

Compute

Four Proxmox VE nodes provide the compute foundation for centrally managed virtual machines and containers.

LAYER 02

Distributed Storage

Ceph software-defined storage provides shared distributed storage designed for improved resilience.

LAYER 03

40G Network

High-speed networking supports the data movement required by the clustered compute and storage environment.

LAYER 04

Backup & Recovery

Automated Proxmox Backup Server workflows provide a more structured and accessible recovery process.

The Outcome

A more resilient, manageable and future-ready infrastructure.

The new platform transformed a limited legacy environment into a centralised infrastructure capable of supporting both virtual machines and containers with improved availability, storage resilience and recovery capabilities.

✓

High Availability

A clustered platform designed to improve workload availability and reduce the impact of individual node failures.

✓

Centralised Infrastructure

Virtual machines, containers and cluster resources can be managed from a unified platform.

✓

Improved Storage Resilience

Ceph distributed storage replaced isolated storage with a shared software-defined storage layer.

✓

Simplified VM Management

Centralised management makes it easier to create, operate and maintain virtual machine workloads.

✓

Easier Backup & Restoration

Automated backup workflows provide a more straightforward process for restoring protected virtual machines when required.

✓

VM & Container Platform

The environment supports the creation and management of both virtual machines and LXC containers.

✓

Reduced Proprietary Dependency

The open-source platform reduced dependency on proprietary virtualisation technologies.

✓

Improved Scalability

The clustered architecture provides a stronger foundation for future infrastructure growth.

✓

Operational Visibility

A centralised platform improves visibility into cluster resources and workload management.
