  2. Designing & building efficient data centers

  3. Data Centers There are four steps to building and operating a data center. • Evaluation of alternatives • Construction • Maintenance and Operations • Expansion

  4. Evaluating Alternatives • Buy • Only financial feasible for large organizations • Logistically cumbersome • Rent • High monthly cost: up to $45 sq ft / month1 • Rapid deployment • Construct • 1Grubb & Ellis, “Study: Telco Vacancies at 45 Percent”.

  5. Construction • Entirely Custom solution. • Average cost $500-600 / sq ft to build.1 • 12-18 months expected completion time.2 • Often built with little or no prior experience. • Takes away from the organization’s core business. • Often not built with future growth in mind. • 1CIO Update, ” Selecting a collocation data center”. • 2Energy User News, “Consultants face Difficult New Questions in Evolving Data Center Design”

  6. …what matters most to the computer designers at Google is not speed but power – low power, because data centers can consume as much electricity as a city.1 - Eric Schmidt, Google CEO 1 New York Times Technology Section, 29 September 2002; “Intel’s Huge Bet Turns Iffy”

  7. Operation and Maintenance • Modern data centers generate 75-200 Watts / sq ft.1 • 10x increase in the last 20 years. • Cooling accounts for 40 – 60% of the electrical load in a data center.2 1Energy Users News; “Taking the Data Center Power and Cooling Challenge” 2Rawlson King, the WHIR.com

  8. Expansion • In five years, the average company will manage ten times the amount of data that it does today.1 1Energy Users News; “More Power Needed”

  9. There is a window of opportunity to define and implement best practices for data centers before the next information technology serge.

  10. PlanetTen Approach Use commodity enclosures to build productized data centers tailored to individual customer needs.

  11. PlanetTen Data Centers • 40’ or 20’ standard portable data center • Delivered ready in 90 days. • Racks or shelving • All equipment for transportation. • Focused on efficient thermal layout.

  12. HVAC • Modular 5 ton units with economizers • Capable of dissipating 12.1kW (95F ambient) each • Economizer Mode • ~10% power of normal AC Mode • 45% overall savings in power usage

  13. Thermal Layout • Hot aisle, cold aisle design for maximum efficiency • Hot air is returned to the outside by ceiling ducts. • Cold air is forced through the machine.

  14. Decision Process • System components: • Processor • Storage • Network • Mounting: racks or shelves? Cooling and electrical layout are based on the answers to the above questions.

  15. Example Data Center • White-box storage cluster: • AMD 2100 Processors • 4 Maxtor 250 GB Hard drives • Shuttle MK35N Motherboard • CasEdge DF-137 case • Resulting Data Center • Space for 720 units • 93.6 kW peak power usage • 8 HVAC units • Total price: $96,000.

  16. Energy Savings • Assumptions: • A1 Commercial PGE Rate = $0.17668 / kWh • 80% average system utilization = 74.88 kW • Power with conventional cooling = 149.76 kW • Economizers used 50% of the time (San Francisco climate) • Power bill per year: • Traditional: $231,786.07 • With economizers: $153,558.27 • Savings: $52,151.87

  17. Building the next generation data center

  18. Appendix

  19. Electrical Layout • Three 20A circuits per rack; 1 per 2 levels. • 72+1 110V circuits, 8 220V circuits • Additional 110V circuit is for lighting • Circuit breakers located in front of container • Emergency shutoff inside left of doors.

  20. Tolerances Source: “Enterprise Data Center Design and Methodology”, Rob Snevely. Sun Microsystems Press (A Prentice Hall Title), 2002.

  21. Shelving • 24 36’x18” shelves • 6 shelf levels • Center aisle is 30” • Outside aisles are 12”.

  22. Digital Data • Digital data is growing at 90% annual according to Meta Group. • Increased use of rich media will require greater storage capacity. • IDC estimates that email volume alone will increase from 31 billion messages per day to 60 billion per day in three years.

  23. Bandwidth • SF to Sydney: 14days • 6800 TEU => 3400 Petabytes • 6.94 Gigabits/sec per container • 3,219,596 Gigabits/sec (1,287,838 OC-48 lines)
