Need for energy efficiency in Datacenters Continuously increasing Energy consumption for growing computing needs!!!!!! Need for energy efficiency in Datacenters Continuously increasing Energy consumption for growing computing needs!!!!!! Energy use of computing devices is an increasing concern – Total U. S use is about 100 B Kwh. in 2006* – Projected to grow 3 -4% per year* – Supply – Demand gap for India continues to increase – Energy costs likely to continue increasing – Supply issues; potential climate change regulations 3 3 The same is reflected in the Datacenter energy consumption also. . U. S. data center electricity use ~30 B Kwh/yr. * Energy is top data center operating cost Public perception that data centers are driving up energy use Worldwide server shipments 7 M/ year and growing 10% per year * * Source – Energy Efficient computing – Tim Higgins, Intel Dt: 5/8/07 3/17/2018

Challenges to Energy Efficiency in Data centers – Right Sizing of facility infrastructure considering Challenges to Energy Efficiency in Data centers – Right Sizing of facility infrastructure considering appropriate load diversity. – Facility side redundancies not in line with business needs. – Legacy servers yielding less performance per watt of power consumed as compared to the current generation multi core servers. – Lack of energy efficiency as a key decision vector for appropriate , optimum work load allocation to Servers. – Lack of correlation of Facility utilization and IT performance measurements. “ A clear consistent way of measuring DC Efficiency which includes business value, IT performance and Facility Utilization aspects would helps us address the above challenges ” 4 4 3/17/2018

The outcome of facility utilization measurements. . The actionable triggered from the analysis of The outcome of facility utilization measurements. . The actionable triggered from the analysis of the measurements. . 1. Paralleling of UPS to increase the utilization levels thereby reducing efficiency and distribution Losses. 2. Increasing the PAC tempt Set point from 19 Deg C to 23 Deg C. 3. Humidity controls made operational as needed in DC (was found to be required only for 3 Months in Bangalore) 4. Effective Air management inside the DC. 5. LED lighting for emergency lighting inside the DC. 6. Regular lighting utilization also controlled and managed. The above activities were rolled out in the DC at various times during the year based on the inputs identified from metering and measuring of the facility consumption in the DC and this resulted in improving the PUE to 1. 81 from 1. 99 13 3/17/2018

What next after Facility Efficiency…. Why facility efficiency is just the beginning and means What next after Facility Efficiency…. Why facility efficiency is just the beginning and means but not the end? ? ? ? ? – Refer the cost savings in our case study. . – An annual power cost savings of 77 K USD realized in 2008 by improving PUE from 1. 99 to 1. 81 – Potential annual power cost savings of additional 55 K USD targeted in 2009 by improving PUE from 1. 81 to 1. 68. – However improving PUE is still a finite activity. Beyond a reasonable value improvements in PUE will not yield an effective ROI as the returns are of diminishing nature. To ensure a significant ROI in the DC efficiency initiatives the need is to focus holistically including the IT utilization aspects and its impact on facility efficiency. 16 3/17/2018
