Abstract
Resilient Compute Foundations
The synergy of server virtualisation and software-defined storage constitutes the bedrock of contemporary digital infrastructure. When architected with precision, these technologies enable elasticity, high availability, and operational efficiency.
Platforms
Virtualisation Platforms
KVM-Based Stacks
- Open-source flexibility
- Deep Linux integration
- Cost-effective at scale
- Strong automation support
Proxmox VE
- Integrated storage (ZFS/Ceph)
- Built-in HA clustering
- Web-based management
- Container support (LXC)
Clustering
High-Availability Architecture
Cluster Design
Robust quorum and predictable failover:
- Minimum three-node clusters for split-brain prevention
- Dedicated management and storage networks for bandwidth isolation
- Predictable failover behaviour ensuring SLO compliance
Failure Domains
Comprehensive fault isolation:
- Host-level isolation contains hardware/hypervisor failures
- Storage fault containment decouples compute from storage failures
- Network path redundancy eliminates single points of failure
Storage
Software-Defined Storage
Strategic storage architecture balancing performance, resilience, and cost.
Hyperconverged
Ceph and ZFS providing distributed, fault-tolerant storage with compute co-location.
Shared SAN/NAS
Centralized storage arrays with iSCSI/NFS protocols for legacy integration.
Hybrid Models
Performance tiering combining SSD for hot data and HDD for capacity.
Data Locality
Awareness of data placement to optimise latency and bandwidth utilisation.
Resilience
Backup & Disaster Recovery
Backup Strategy
Image-level and application-aware backups ensuring recovery consistency for stateful workloads.
Off-Cluster Replication
Geographically separate replication for comprehensive disaster tolerance.
RPO/RTO Alignment
Defined recovery objectives meticulously aligned with business continuity requirements.
Regular Testing
Full-lifecycle restoration exercises validating the entire recovery chain.
Continuous Monitoring
Proactive failure detection ensuring backup integrity and performance.
Isolation & Immutability
Air-gapped or immutable storage protecting recovery capability from production faults.
