Sun Microsystems Completes Next-Generation, Energy Efficient Datacenters in US, UK and India

Consolidation and Design Breakthroughs in Santa Clara, Calif. Datacenter Reduce Sun's Energy Bill by 60 % and Garner Nearly
$1 Million in Utility Rebates and Awards

Santa Clara, Calif., August 21, 2007 / PRNewswire / – As part of the company's ongoing commitment to greening its global operations, Sun Microsystems (NASDAQ: SUNW) today publicly unveiled three active, new datacenters in Santa Clara, California; Blackwater, U.K.; and Bangalore, India. Put into operation between January and June of this year, all three datacenters were built using breakthrough designs and next-generation energy efficient systems, power and cooling. Sun estimates that the company's datacenter efforts will save the planet nearly 4,100 tons of CO2 per year and trim 1% from Sun's total carbon footprint.

The Santa Clara datacenter is the largest of the three datacenters at 76,000 square feet. Phase One of the Santa Clara project began with a hardware consolidation and refresh project that took three months, increased compute power by more than 450% and is expected to save $1.1 million in energy costs a year. Accomplished in an aggressive 12 months, Phase Two involved designing the Santa Clara space and installing the new hardware. Sun estimates that Phase Two will yield an additional 30% savings in energy costs. Silicon Valley Power, a local utility company, has recognized the breakthrough efficiencies and design of Sun's Santa Clara datacenter by giving Sun nearly $1 million in rebates and awards.

"There are many projects, big and small, that businesses can begin today to make a difference. It doesn't have to be complicated and the ROI can be larger than you'd imagine," said Dave Douglas, Vice President of Eco Responsibility for Sun Microsystems. "We're opening the doors on our new global datacenters today to show what's possible in a relatively short time frame and because we believe strongly that sharing is the path to a greener world."

Through its efforts in California, the UK and India, Sun has reduced 267,000 square feet of datacenter space worldwide into approximately 133,000. Today, Sun will hold an event for customers at the Santa Clara facility to share best practices from the company's global datacenter efforts. Building on Sun's heritage of sharing and open source, the company will post key learnings from the project free of charge at
www.sun.com/aboutsun/environment/green/datacenter.jsp to help other companies green their own datacenters and be kinder to the planet.

"New standards in datacenter design and management are not only good for the environment, but they are also good for a company's bottom line," said Sun Microsystems CIO Bob Worrall, who is responsible for reducing Sun's corporate datacenter energy usage by 20% in fiscal year 2008. "Most CIOs don't even see an energy bill, which makes little sense given that datacenters can consume a significant portion of a company's total energy draw. By working together, CIOs and CFOs can direct their efforts to successfully squeeze 'green' into – and out of – the datacenter."

The three new datacenters run exclusively on Sun's line of energy efficient products, including Sun Fire(TM)T1000/T2000 servers, Sun's x64 servers and the Solaris(TM) Operating System. Today Sun also announced a suite of programs and solutions under its Eco Innovation(SM) Initiative to help customers architect more energy efficient datacenters and save money. For more, please visit

About Eco Responsibility at Sun

Sun's Eco Responsibility Initiative is guided by three principles: Innovate, Act and Share. Sun innovates by making products and services that are both good for the environment and good for business. Sun acts by operating in an open, eco-conscious way. Sun shares by making information and technology available to others so that we can all move forward and participate in an increasingly sustainable way. One of Sun's many Eco Innovation (SM) products includes the Sun Fire/Sparc Enterprise T1000/T2000 server, which is three to five times more energy efficient than its nearest competitor. Sun also takes responsibility for its products through end of life with its Global Takeback Program, which has allowed 95% of returned products to be recycled or reused. Sun is greening its own operations through programs like Open Work, which saves our environment 30,000 metric tons a year by allowing employees to work from home or in a flexible office.
