Look beyond the server
A data centre also depends on networking, storage, power, cooling, monitoring, fire protection and physical security.
Data-centre components
| Component | Purpose |
|---|---|
| Rack server | Provides CPU, memory and local storage in a standard enclosure. |
| GPU server | Accelerates AI, analytics and simulation workloads. |
| Storage system | Retains datasets, applications, backups and model artefacts. |
| Network switch | Connects servers, racks and external networks. |
| UPS and PDU | Protects and distributes electrical power. |
| Cooling system | Removes heat and maintains safe operating conditions. |
| Monitoring sensors | Track temperature, power, airflow, faults and access. |
Reliability principles
- Remove single points of failure where the service requires continuous availability.
- Monitor temperature, power, capacity and hardware health.
- Separate production traffic, management traffic and storage traffic where appropriate.
- Plan maintenance, replacement and secure disposal across the hardware lifecycle.
