  3. 3. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 European Commision code ● http://re.jrc.ec.europa.eu/energyefficiency/
  4. 4. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Basic requirements for IT-equipment ● Power Supply „CBEMA“-Curve ● Air Conditioning 20 - 26 °C 20 - 80% rF ● Availability Tier 1 to 4
  5. 5. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Energy Costs, Trend: rising ● 0,12 € per kWh is an average value for electrical power costs in Europe ● Based on that price the annual cost of power supplied to 1 kW of IT-equipment is around 1.000,- €. (365 x 24h = 8760h x 0,12 Kr = 1.051,20 €) ● The Network Critical Physical Infrastructure needs around the same amount of power ! => 1.000 € per kW per year ● During the typical 10-year-Lifetime of a datacenter every 1 kW of IT-load cost around 20.000,- € ! and 1kWh = 600g CO2 !
  6. 6. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Where does Hardware inefficiency go? .001% 99.9997% of WATTS IN becomes heat .0003% of WATTS IN becomes computation Silicon Business Apps 99.999% .001% Inefficiency (waste) Useful Work Computing Hardware 60% 40% 60% 50% Physical Layer 50% 50% IN
  7. 7. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Data Center Infrastructure Efficiency DCiE = Watts delivered to IT load Watts IN to data center This definition follows the US Environmental Protection Agency ENERGY STAR Program. Detailed information can be found in APC-MGE Whitepaper 157 This ratio gives a value between 0 and 1 and is normally expressed in % => Higher value = higher efficiency
  8. 8. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Optimising the IT ●Remove all old or unused hardware ●Use modern IT-equipment with high efficiency power supplies (90%+) and intelligent power management ●Virtualization for efficient loading of IT-equipment (increase from 15% to 80% load) ●Don‘t forget the peripherals and desk-tops („Stand-by“)
  9. 9. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Rightsizing ! 2(N+1) power N+1 cooling
  10. 10. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Save Energy with State-of-the-Art UPS systems size with minimal oversizing, „hot-add“ power if needed  very high efficiency, even at low load and in redundant configuration, Values for 100% load are not sufficient for E.eff. installations
  11. 11. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Sample: Saving by right sizing Given: 1 MW of IT power Increase efficiency factor of UPS from 0.92 to 0.96 saves 58.856,- €/a or 294 tons CO2/a
  12. 12. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 IDC Research ● “Through it’s research IDC has found that an increasing number of datacenters are close to reaching their power and cooling thresholds, or are anticipating doing so in the near future.” ● “This in turn is constraining IT’s ability to expand to keep pace with business requirements, as well as increasing the risk of failures associated with hotspots in the datacenter.” ● “IDC believes datacenter operators will require enhanced tools to optimize energy efficiency and to maximize capacity within their environments.” ● “The cost to power and cool the installed base of servers is increasing a growth rate that is four times the growth rate of new server spending.” ● Surce: September 19, 2008
  13. 13. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Optimising the Datacenter cooling ●rising the acceptable air-inlet-temperature of the IT-equipment to 20 -26°C leads to higher efficiency ●higher the chilled water temperature (e.g. 12°C instead of 6°C) means that the compressor needs less power ●use of chilled water allows the „indirect free cooling“ (Eco-Mode) which is even more efficient with higher chilled water temp and higher air inlet temps ●avoid dehumidifying by higher heat exchanger temps saves the additional humidifying energy Savings: ~ 4% per °C 10-15% ~ 33% 3-5%
  14. 14. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Gartner Rerearch ●The most important result - Containment hot or cold aisles can reduce data center energy costs by 30%. ●“For any data center that is under pressure to cut costs or that just wants to improve energy efficiency, containment can provide a method for substantially reducing energy costs associated with cooling and can extend the capacity of cooling plants.” ●“Hot-aisle containment is well-suited for new data center construction or for extensive data center renovation projects.” ●“Hot-aisle containment is typically implemented using specialized racks with in-row cooling (such as the APC InfraStruXure system), or by establishing other types of barriers to contain the exhaust air in the hot aisles” ● Source Gartner Research Publication Date: 17 October 2008
  15. 15. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Hot Air Containment Systems ! High density and high efficiency over 30 kW of cooling per rack possible
  16. 16. APC by Schneider Electric – Eduard Bodor – 02. Dec. 2009 Cooling/Power savings by Fan Laws Operating Point A: RPM = 250 Static pressure (SP) = 1,2 bar Power consumption (P) = 35Watt What happens if we change the air flow demand to be tripled? Air Flow related directly to RPM: => RPM triples = 750 SP varies as the square of RPM: => SP = 10,8 bar (Not important for our discussion) Power consuption raises by power of 3: => Power consumtion = 900 Watt Operating Point B: RPM = 750 Static pressure = 10,8 bar Power consumption = 945Watt SP (new) RPM (new) SP (old) RPM (old) =( ) 2 P (new) RPM (new) P (old) RPM (old) = ( ) 3 AirFlow (new) RPM (new) AirFlow (old) RPM (old) =
