6. 6 Old Way Rackable Way A Vast Improvement

7. 7 The Data Center Dilemma Density Density Power Power Heat Heat Operations Operations

8. 8 Maximum Density Highly differentiated server & cabinet designs –Half-depth form factors for back-to-back mounting –2x density levels = 88 servers per cabinet = 352 cores –Ability to cool fully populated cabinet of systems Back-to-back mounting 352 cores per cabinet Foundation Series Rack Mount Servers & Storage Scale Out Hybrid Blade Servers Back-to-back and side- to-side mounting 352 cores per cabinet

9. 9 Total flexibility and configurability –Open architecture, X86 designs –Customer and order specific bill of material –Rapid new technology adoption –Range of memory, disk formats (SCSI, SATA, IDE, SAS) and RAID configurations Leading edge development around AMD and Intel chipsets Best-of-breed partners –Full support for range of software platforms World-class OS expertise –Linux, Windows, Solaris Flexible Configurations

10. 10 Lower Power Consumption Reduce power consumption in the server –Use low wattage parts (CPU, memory, fans) –Eliminate unnecessary components –Map designs to data center power availability –Less power = less heat = greater reliability Reduce losses associated with getting power to servers –Industry’s first DC Power technology AC-to-DC conversion at cabinet, row and data center level 10-30% lower power draw* 20-40% elimination of heat at server level* Maximize density to available power in legacy data centers Only supplier to provide Direct DC powered servers and storage –In AC systems, carefully match power supply to system power draw *Source: Lawrence Berkeley/California Energy Commission, 6/2006

11. 11 Distributed DC Power Which would you rather have in your server? Rackable Systems DC Power Supply Competitors’ AC Power Supply Small: 29 cu in (no moving parts!) 2 million hours MTBF Dual power feed 93% efficiency Very low thermal signature Big: 240 cu in 100,000 hours MTBF Need (2) for Dual power feed 73% efficiency High thermal signature Choose the cooler, more efficient, more reliable solution:

12. 12 Cabinet DC Power Technology Highly reliable DC power supply (93% efficient) replaces standard AC power supply (73% efficient)* Rectifiers convert AC input to DC power for 10% increase in power efficiency DC distribution bars inside cabinet deliver N+M redundant DC power to individual servers 20-40% elimination of heat* Deployed in any existing AC data center *Source: Lawrence Berkeley/California Energy Commission, 6/2006 Power Cost Savings and Higher Reliability

13. 13 Row Level –One rack used to power entire row of cabinets –Added redundancy, reduced cost –Reduce number of circuits –Eliminate need for AC PDUs in data center Row & Data Center DC Solutions Data Center Level –Additional efficiency benefit (up to 30%) –Improved thermal shift/corresponding HVAC benefits –Maturing technology Server Cabinets DC Bus Duct Distribution System Power Cabinets

15. 15 Customer Case Study

16. 16 DC Power Testimonials DC Power Testimonials “Rackable has allowed us to increase our global hardware capacity by more than 50% without increasing our electricity costs.” – CIO of Webex to Forbes Magazine, June 2006 “DC Power keeps the units considerably cooler within the chassis themselves and saves us somewhere between 10 and 20 percent over the AC-powered alternative." – Lead Engineer at University of Florida to CNET, March 2006 By purchasing a DC-powered solution, eWEEK Labs believes organizations will increase server reliability while lowering monthly power costs. – eWeek Labs, March 2006 “We saw the power savings right away when we put in the Rackable Systems servers.” – President of Spectrum to eWeek, March 2006 “Using DC powered [servers], we're saving money on energy, while receiving 20% more compute power in the same footprint." – VP Technology of Right Media to Tech Target, Jan 2006

17. 17 Cooling Strategies Better heat evacuation –Back-to-back mounting enables central air plenum in cabinet –Louver system allows vectoring of air to returns (either upward or downward inside plenum) –Elimination of ‘hot aisle/cold aisle’ phenomenon –Reduces requirements on air handlers –No additional power needed to evacuate hot air Every 100W of power consumed by a server requires 70W power for HVAC to cool it –Reduced power = less heat = reduced HVAC costs = higher MTBF

18. 18 Operational Savings Better serviceability –I/O in front for easy access –Roamer™ remote management –Modular power mating –Elimination of rail kits & clean cabling Turnkey deployments –Designed to meet customer-specific data center space and power requirements –Fully racked, stacked and cabled –System/cabinet-level power optimization –Configurations specific to customer –Comprehensive support and sparing packages –World-class technical consulting
