Proactive and reactive thermal optimization techniques to improve energy efficiency in data centers

Marina Zapater presents her work at the PICATA Workshop. This workshop is intended to know the diverse groups of people recently incorporated thank to PICATA programme of Moncloa campus and who are researching and assessing the clusters.

The Program for International Talent Recruitment (PICATA) has focused on bringing in students and researchers from all over the world, in a determined effort towards internationalization and talent recruitment with different actions. The PICATA Programme offers sholarships for the development of PhD thesis marked by at least two practising doctors from the two associated Universities, the UCM and the UPM, with the possibility of participation by doctors from the other associated Institutions within the context of the Campus Moncloa in these areas: Global Change and New Energies, Materials for the Future, Agri-food and Health, Innovative Medicine, and Heritage.

4. Motivation Marina  Zapater  |  Workshop  PICATA  |  14-­‐02-­‐2013   4   •  Power  consumpQon  in  data  centers   –  1.3%  world  energy  producQon  in  2010   –  USA:  80  billion  KWh/year  in  2011  =  1.5xNYC   –  250  billion  KWh/year  in  2010   •  More  than  43  Million  tons  of  CO2  /  year   •  More  water  than  paper,  automoQve,  petrol,  wood   or  plasQc  industry                      Jonathan  Koomey.  2011.  Growth  in  Data  center  electricity  use  2005  to  2010  
5. Motivation Marina  Zapater  |  Workshop  PICATA  |  14-­‐02-­‐2013   5   •  It  is  expected  for  total  data   center  electricity  use  to   exceed  400  GWh/year  by   2015.   •  The  required  energy  for   cooling  will  conQnue  to  be  at   least  as  important  as  the   energy  required  for  the   computaQon.   •  Energy  op4miza4on  of   future  data  centers  will   require  a  global  and  mulQ-­‐ disciplinary  approach.   0   5000   10000   15000   20000   25000   30000   35000   2000   2005   2010   High-­‐end  servers   Mid-­‐range  servers   Volume  servers   0   50   100   150   200   250   300   2000   2005   2010   Infrastructure   CommunicaQons   Storage   High-­‐end  servers   Mid-­‐range  servers   Volume  servers   5,75  Million  new  servers  per  year   10%  unused  servers  (CO2  emissions   similar  to  6,5  million  cars)   World  server  installed  base  (thousands)   Electricity  Use  (billion  KWh/year)  
6. State of the Art Energy Savings for different abstraction levels AbstracQon  level   •  Higher  levels  of   abstracQon  bring   more  benefits   •  ApplicaQon-­‐level   sQll  has  to  be   explored.   SoluQons  proposed  by  the  State  of  the  Art   6   Marina  Zapater  |  Workshop  PICATA  |  14-­‐02-­‐2013  
7. Our perspective   •  Using  the  knowledge  about  the  energy  demand  of  the   applica4ons,  the  features  of  the  computa4on  and   cooling  resources  to  apply  proacQve  opQmizaQon   techniques   •  Global  strategy  to  integrate  mulQple  informaQon   sources  and  coordinate  decissions  to  reduce  overall   power  consumpQon.   Marina  Zapater  |  Workshop  PICATA  |  14-­‐02-­‐2013   7   Proactive and reactive holistic approach
