Flexible Configurations n Total flexibility and configurability – – Open architecture, X 86 designs Customer and order specific bill of material Rapid new technology adoption Range of memory, disk formats (SCSI, SATA, IDE, SAS) and RAID configurations n Leading edge development around AMD and Intel chipsets n Best-of-breed partners – Full support for range of software platforms n World-class OS expertise – Linux, Windows, Solaris 9

Lower Power Consumption n Reduce power consumption in the server – – n 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 10

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

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

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

Customer Case Study 15

DC Power Testimonials n “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 n “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 n By purchasing a DC-powered solution, e. WEEK Labs believes organizations will increase server reliability while lowering monthly power costs. – e. Week Labs, March 2006 n “We saw the power savings right away when we put in the Rackable Systems servers. ” – President of Spectrum to e. Week, March 2006 n “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 16

Cooling Strategies n Every 100 W of power consumed by a server requires 70 W power for HVAC to cool it – Reduced power = less heat = reduced HVAC costs = higher MTBF n 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 17

Operational Savings n Better serviceability – – n 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 18
