Power Usage Effectiveness Index- Electrical Systems DATA CENTER Hareesha K Texas Instruments EFFICIENCY –MACRO LOOK LESS EFFICIENT SYSTEMS OPTIMISED EFFICIENT SYSTEMS IT IS OUR RESPONISIBLITY TO CREATE & OPERATE HIGHER EFFICIENT SYSTEMS TO BE IN BUISENSS AS WELL AS TO REDUCE IMPACT ON ENVIRONMENT DATA CENTER – POWER DISTRIBUTION Case for need LIGHTING POWER, 0.8% Misc POWER, 1.0% UPS COOLING POWER, 3% BLOWER INPUT POWER, 6% All Power Measured in KW COOLING INPUT POWER, 22% UPS INPUT POWER, 68% Power Usage Effectiveness (PUE) = Total Power Total Server Power Datacenter Infrastructure Efficiency (DCiE) = UPS Electrical Power -68% Cooling Power -31% Lighting & Misc -1% 1 PUE NEED TO LOOK AT ELECTRICAL SYSTEM AS IT CARRIES 68% OF TOTAL POWER CONSUMED BY DATA CENTER BUILD PROCESS CYCLE DATA CENTER INFRASTRUCTURE TEAM/FACILITIES TEAM BUSINESS MODEL BUISNESS REQUIREMENT INPUT OUTPUT PROCESS CONSULTANTS EXPERIENCE INTERNAL STANDARDS Monitoring Design concept Selection process Design process ENERGY = POWER X PAST Changes are the only constant Requirements, Design concept and Technology is always TIME FUTURE CHANGING • The system efficiency depends on Technology available at the point of time of project execution. •Total Cost of Owner ship is not completely thought of. • Knowledge of availability of efficient products in the market • Known devil is better than a angle • Increased Components compared to normal Electrical Systems due to CAPACITY, RELIABILITY, AVIABILITY requirements • The replacement cost of equipment is huge • No standards for ground level tweaking for better efficiency. ONLY CONSERVATION IS CONSTANT AND POSITIVE WHAT WE LEARNT Procure & Operate Single operating Voltage System Xfrmer Maintaining single operating voltage reduces unnecessary voltage conversions, regulation losses G Operate at higher voltage level at Server Input Operate at higher voltage level at Server Input reduces the current requirement, this will reduces the losses. 415V Max Voltage (90-260VAC) Nominal Voltage (100-240VAC) (Source: Web site) TYPICAL ELELCTRICAL SYSTEM Concentrate on the component which directly impact your Energy Consumption WHAT WE LEARNT Evaluate your Devices used in Datacenter for Energy consumption Evaluate devices planned to use in Data center for power , cooling, environmental requirements. This will help us to choose between similar capable devices in terms of energy consumption and hence reduce your power consumption.
