How should we measure data center efficiency in the AI era? For years, PUE and WUE have been the standard benchmarks for infrastructure efficiency. However, the rise of AI workloads is introducing a new metric to the conversation: Tokens per watt. Since AI output is measured in tokens, analyzing efficiency through this lens helps organizations understand the direct computational value generated per watt. While optimizing for token output is critical for business performance, the industry still faces the challenge of aligning these processing gains with broader environmental commitments. At Iron Mountain Data Centers, we view this shift as an opportunity to support both performance and sustainability. As we integrate advanced liquid cooling and design for high-density architectures, our focus remains on helping colocation partners scale efficiently. By pairing these technical advancements with solutions like our Green Power Pass, we aim to ensure that high-performance compute and progress toward decarbonization goals move forward together. The metrics are evolving, but the core objective remains the same: balancing operational performance with responsible growth. 👉 Read the full analysis from Data Center Dynamics: http://spr.ly/6041BD176P
