Enterprise Virtualisation & High-Availability Power Redundancy
Server consolidation and automated off-site replication for a regional distribution enterprise
The client operated six ageing physical servers with no hardware redundancy. Power outages frequently caused corrupted database indexes, while manual backups to portable drives were erratic and untested under recovery drills.
Engineered a consolidated dual-node hyperconverged cluster using Proxmox VE with live storage replication. Integrated dual enterprise online double-conversion UPS units tied to clean inverter solar inputs, complemented by automated nightly air-gapped snapshots.
Technical Overview & Background
The client operates high-volume distribution hubs requiring continuous access to inventory and billing systems. Prior to HiTa Synergy’s architectural intervention, intermittent power fluctuations in Harare led to periodic filesystem corruptions on legacy bare-metal servers.
Architectural Solution
HiTa Synergy deployed a redundant two-node virtualisation cluster backed by high-speed ZFS storage with automatic failover.
Key Architectural Components
- Isolated Storage Network: Dedicated 10GbE backplane for low-latency block-level replication.
- Clean Power Filtering: High-efficiency double-conversion power units that isolate equipment from voltage spikes and harmonics.
- Automated Verification: Nightly sandbox boot tests verifying backup integrity without disrupting live operations.
