Sun’s Robust Ecosystem for Solaris on x86 Expands to Include 15 New Financial Services Applications

SANTA CLARA, Calif.
September 21, 2005

During its quarterly Network Computer ’04 launch today, Sun Microsystems, Inc. (Nasdaq: SUNW) announced the growth of the Solaris x86 Operating System (OS) ecosystem with more than 1,100 solutions currently available from more than 700 of Sun’s business application software partners, an increase of 17 percent in the last six months. Independent software vendors (ISVs) around the world have adopted the Solaris OS for Sun’s AMD Opteron and Intel Xeon processor-based systems. At an event in New York City today, Sun also announced it has added 15 new premier financial services application software partners to the Solaris ecosystem.

“The operating system is irrelevant if it lacks world-class ISV support. And a server without that OS is a doorstop,” said Jonathan Schwartz, president and COO at Sun Microsystems. “Unlike some of our competitors, Sun is making it easy for ISVs to qualify to our systems. We’re making every business-critical application our customers need available for Solaris on AMD Opteron processor-based systems so that customers benefit from the broadest possible range of choices.”

The application momentum underscores Sun’s successful strategy to provide the market’s most widely adopted UNIX(R) operating system – the Solaris OS – with its rock solid security and enterprise-class features, at highly competitive prices on a wide variety of Sun platforms.

“VERITAS’ decision to broaden its support of the Sun platform to include Solaris on x86 and Sun’s decision to expand its already significant commitment to VERITAS solutions represents a win for customers and a win for each company,” said Gary Bloom, chairman, president and CEO, VERITAS Software. “With the collective strength of our partnership and our established track record among the Global 2000, VERITAS and Sun are uniquely positioned to deliver customers a high-performance, scalable infrastructure while simultaneously lowering operating costs.”

ISVs spanning multiple industries worldwide have already committed to Sun as a partner. Today’s featured financial services partners include: BMC Software, Inc., Computer Associates International, Inc., EMC Legato Software, Hyperion Solutions, Mainsoft Corporation, Oracle, Rogue Wave Software, Stellent, Inc., Sybase, Inc., TIBCO Software, and VoiceGenie. Other application software partners include: Bright Software, ECnet Ltd., EcQuaria, Excellence Network Co., FatWire Corporation, iESLab, IMAZIC, Jaatayu Software, Lasersoft, Oracle, Neusoft, Runqian, Tarantella, Inc., Transversal e Networks Pvt.
