Overview

ISO/IEC 30134-4:2017 defines IT Equipment Energy Efficiency for servers (ITEEsv) - a Key Performance Indicator (KPI) for quantifying the energy efficiency capability of servers in a data centre. ITEEsv measures the maximum processing performance per kilowatt across all servers (or a defined server group) using standardised or context‑specific server performance benchmarks. The standard is intended to help data centre owners/operators track and improve the aggregate energy effectiveness of their server fleet.

Key Topics and Requirements

Definition and purpose: ITEEsv represents maximum server performance per kW and focuses on capability (performance per unit energy), not real‑world utilization or power‑management behavior.
Primary formula: ITEEsv = (sum of SMPEi) / (sum of SMPOi)
- SMPE = Server Maximum Performance (peak performance from an accepted benchmark)
- SMPO = Server Maximum Power (average power during the benchmark run), in kW
Benchmark rules:
- Use a single benchmark method for all servers in a group; do not mix benchmark types across the same group.
- Benchmarks must report both power and performance and have a run‑to‑run effectiveness variation ≤ 5%.
- Benchmarks should correlate strongly with server power consumption and be generally accepted for the server class (examples: SERT, SPECpower).
- Recommended characteristics include portability across architectures,
