Key Cost Drivers
- •Rack space power (kW) and cooling colocation fees
- •Hardware capital depreciation (CAPEX amortized over 4 years)
- •Data center cross-connect fees
Waste Vulnerabilities
- •Single-drive failures causing network rebalance storms
- •Under-utilized rack space commitments
Mitigation Playbooks
- •Enforce 4-year hardware lifecycle replacement schedules
- •Throttling Ceph recovery bandwidth during business hours
