HP Receives Top UNIX Ranking from D.H. Brown

HP-UX 11i Rated No. 1 UNIX Operating System

HP (NYSE:HPQ) today announced that its HP-UX 11i operating system has been rated the No. 1 UNIX® operating system in a recent report from industry analyst firm D.H. Brown Associates, Inc. Entitled "2002 UNIX Function Review," the report evaluated the industry's top UNIX operating systems according to an extensive and stringent set of criteria for enterprise customers.

HP-UX 11i garnered the top spot in all five of the report's categories against competitive offerings that included Sun's Solaris 8 and IBM's AIX 5L operating systems. HP-UX 11i led the D.H. Brown scorecard in reliability, availability and serviceability; Internet and Web application services; directory and security services; systems management; and scalability.

"HP's focus and investment in HP-UX have effectively moved this key operating environment to the forefront of the UNIX industry," said Tony Iams, vice president, D.H. Brown Associates. "In addition to taking the top overall spot in our report and securing an unprecedented top ranking in every category, HP-UX had a particularly strong lead in the Internet and Web application services category, and it surged forward in the intensely competitive reliability, availability and serviceability category."

HP-UX is a proven operating system that offers the enterprise market world-leading functionality. HP packages UNIX operating systems as integrated operating environments, providing customers with business-critical capabilities to improve their operational efficiencies and reduce their total cost of ownership.

With HP-UX 11i, HP provides customers a clear and stable path to the future by offering complete binary compatibility between the PA-RISC and Intel® Itanium™ architectures. A broad range of independent software vendors support HP-UX, allowing HP's enterprise customers to run key applications that are not available on other operating systems.

"HP-UX 11i is the only operating system that offers the end-to-end performance and scalability needed to handle the wide range of demanding applications on the market," said Mark Hudson, worldwide marketing manager, HP Business Critical Systems. "The results of the D.H. Brown report further validate the strength of HP-UX 11i and clearly reflect HP's ongoing commitment and investment in HP-UX."

HP Tru64 UNIX, now an integral part of HP's UNIX portfolio, also showed strong results in the report, tying HP-UX for the No. 1 spot in the scalability and systems management categories. In addition to continuing to improve the HP-UX advanced feature set, HP plans to bring key features from HP Tru64 UNIX into HP-UX, including TruClusters and Advanced File System capabilities.

"Customers can continue to invest with confidence in HP Tru64 UNIX," said Hudson. "By combining the industry's leading UNIX operating system with a broad product portfolio that ranges from the smallest HP blade server to the largest HP Superdome server, HP is providing enterprise customers unmatched value. And with the addition of key features from HP Tru64 UNIX, HP-UX will be absolutely unstoppable."
