10. 10 © Copyright 2007 EMC Corporation. All rights reserved. Measuring Energy Consumption When provisioning a data center power and cooling, would you… 1.Add up all of the circuits and calculate sum of circuit ratings? Total current = 100A 2.Calculate the sum of all of the equipment specification sheets? E.g., total current = 38A 3.Calculate from actual measurements? E.g., total current = 28A Typical IT load is significantly less than design capacity. 50A Circuit  Configuration  Workload  Duty cycle  Battery recharge state  Redundant power feeds  Safety ratings Additional Considerations

11. 11 © Copyright 2007 EMC Corporation. All rights reserved. Prior to installation you need to understand:  Specific equipment configurations  Normal and abnormal operating modes Calculate:  Base system power –System enclosure –Disk enclosures  Component power –Disk drives by speed –Front-end components –Back-end components –Memory modules  Actual power consumption and heat dissipation for: –Typical load –Maximum load –Special conditions Energy Consumption of YOUR Storage Array
