WP#58 - The Green Grid Data Center Storage Productivity Metrics (DCsP)
This white paper proposes a new set of metrics, data center storage productivity (DCsP), as part of the IT/Energy Efficiency & Effectiveness block within The Green Grid’s framework for improving data center resource efficiency.
DCsP metrics are defined as the ratio of useful storage system work to energy consumed. They make it possible for data center operators to determine the energy productivity of their storage resources, which in turn will allow operators to identify areas of inefficiency and potential improvements.
In addition to defining several specific DCsP metrics (DCsPcap, DCsPio, and DCsPmb), this white paper provides basic guidance on how to measure and use results to drive a storage strategy that increases useful work and/or decreases energy consumption over time.
