Tier-2 Datacenter Build
End-to-end design and deployment of a Tier-2 datacenter facility including power, cooling, network architecture, security zoning, and operational readiness.
Overview
Led the complete design and deployment of a Tier-2 datacenter facility supporting production infrastructure for a global technology organization. The project encompassed facility planning, power and cooling design, network architecture, security zoning, rack elevation, and operational readiness.
Requirements
Tier-2 availability with redundant power and cooling. Support for 100+ physical servers, SAN storage, and network infrastructure. Security zoning compliant with ISO27001. Scalable design for 5-year growth projection.
Power Architecture
Dual utility feeds with automatic transfer switching. N+1 UPS configuration with 30-minute battery runtime. Diesel generator backup for extended outages. Per-rack PDU monitoring with power capacity tracking.
Cooling Strategy
Hot-aisle/cold-aisle containment strategy. N+1 CRAC unit configuration with redundant chilled water supply. Environmental monitoring at rack-level with threshold alerting. Thermal mapping for capacity validation.
Network Design
Three-tier architecture: core switches (redundant), distribution layer, access switches per rack row. Separate VLANs for management, production, backup, and DMZ. Structured cabling with fiber backbone and copper access.
Security Design
Physical access control with badge and biometric authentication. Network segmentation with firewall policies between zones. CCTV coverage of all facility areas. Visitor management and escort procedures.
Monitoring
Environmental sensors for temperature, humidity, and power at rack level. Centralized NOC dashboard for facility health. Automated alerting for threshold breaches. Integration with enterprise monitoring platforms.
Operational Readiness
Runbook documentation for all operational procedures. Maintenance schedule for power, cooling, and network equipment. Incident response procedures and escalation matrix. Staff training and knowledge transfer program.
Business Continuity
Disaster recovery site connectivity with replicated data paths. Backup power tested monthly with documented results. Recovery time objectives defined and validated. Annual business continuity exercise program.

Lessons Learned
- Capacity planning must account for 3-5 year growth, not just current requirements
- Cable management standards established early prevent costly remediation later
- Environmental monitoring integration is critical for proactive maintenance
- Operational documentation is as important as the physical infrastructure
