1. Power Usage Effectiveness Index- Electrical Systems DATA CENTER Hareesha K Texas Instruments

2. ENERGY EXPENSE ENVIRONMENT ENERGY EXPENSE ENVIRONMENT 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

3. Power Usage Effectiveness (PUE) = Total Power Total Server Power All Power Measured in KW UPS Electrical Power -68% Cooling Power-31% Lighting & Misc-1% Datacenter Infrastructure Efficiency (DCiE) = 1 PUE NEED TO LOOK AT ELECTRICAL SYSTEM AS IT CARRIES 68% OF TOTAL POWER CONSUMED BY DATA CENTER DATA CENTER – POWER DISTRIBUTION Case for need

4. BUILD PROCESS CYCLE PROCESS OUTPUT INPUT BUISNESS REQUIREMENT DATA CENTER INFRASTRUCTURE TEAM/FACILITIES TEAM BUSINESS MODEL CONSULTANTS EXPERIENCE INTERNAL STANDARDS ENERGY = POWER X TIME Design concept Selection process Design process Monitoring PAST FUTURE 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. Changes are the only constant Requirements, Design concept and Technology is always CHANGING ONLY CONSERVATION IS CONSTANT AND POSITIVE

5. WHAT WE LEARNT Xfrmer G 415V TYPICAL ELELCTRICAL SYSTEM Procure & Operate Single operating Voltage System Maintaining single operating voltage reduces unnecessary voltage conversions, regulation losses 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. Nominal Voltage (100-240VAC) Max Voltage (90-260VAC) (Source: Web site) Concentrate on the component which directly impact your Energy Consumption

6. 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. TEST before you USE ( Get best out of customers) WHAT WE LEARNT
