Which strategy most directly improves data center energy performance without compromising reliability when properly engineered...

Huawei green data center concepts focus on reducing energy consumption through engineering controls rather than sacrificing resilience. Raising the allowable supply air temperature is a proven efficiency lever because it reduces compressor workload, expands economization opportunities where applicable, and can reduce fan energy when airflow is optimized. However, it must be implemented with airflow management—especially hot/cold aisle containment—to ensure server inlet temperatures remain within safe limits. Adaptive control is critical: monitoring rack inlet temperatures, cooling unit performance, and environmental conditions allows the system to dynamically adjust cooling output, fan speed, and setpoints to match real IT load. This avoids the common inefficiency of “overcooling for safety.” When combined with standardized O&M procedures, alarm thresholds, and continuous trend analysis, the strategy improves overall energy performance while preserving reliability and service continuity. In contrast, permanent oversizing or forcing all redundant systems to run fully loaded wastes energy and can reduce operating efficiency. Properly engineered, monitored optimization delivers efficiency gains with controlled operational risk.
