Fast Guide to measuring efficiency and productivity

 

Efficiency Metric Formula
Asset Efficiency (AE) Asset Efficiency (AE) = (IT Energy Efficiency) x (IT utilization)
Corporate Average Data Center Efficiency (CADE) CADE = Facility Efficiency (FE) x Asset Efficiency (AE)
Data Center Density (DCD) DCD = (Total CPU Cycles) / (Total Data Center Square Footage)
Data Center Infrastructure Efficiency (DCIE) DCIE = (Total IT Equipment Power) / (Total Facility Power)
Data Center Productivity (DCP) DCP = (Useful computing work) / (Total Facility Power)
Deployed Hardware Utilization Efficiency (DH-UE) DH-UE = (Minimum Number of Servers Required for Peak Load) / (Total Number of Servers Deployed)
Deployed Hardware Utilization Ratio (DH-UR) DH-UR = (Number of Servers Running Live Applications) / (Total Number of Servers Actually Deployed)
Facility Efficiency (FE) Facility Efficiency (FE) = (Facility Energy Efficiency) x (Facility Utilization)
Power Usage Effectiveness (PUE) PUE = (Total Facility Power) / (Total IT Equipment Power)
Storage Automation (SA) Storage Automation = (Human Operators) / (Storage Density)
Storage Density (SD) Storage Density = (Storage Utilization) / (Total Data Center Square Footage)
Storage Utilization (SU) Storage Utilization = (Server, Network and Backup Storage in Use) / (Total Storage Available)

The Telecommunications Infrastructure Standard for Data Centers, TIA-942, contains best practices and design considerations for every single aspect of the modern data center. Read a description of the TIA-942 at SearchDataCenter.com or download it from IHS Global Engineering Documents.

Syska Hennessy suggests rating of data center performance on a scale of one to 10 on its Criticality Levels, measuring 11 different points, including power, HVAC, fire and life safety, security, IT infrastructure, controls and monitoring, commissioning and testing, operations, maintenance, operations and maintenance procedures, and disaster preparedness. Read more about Criticality Levels at Syska.com.
