Today, thousands of companies worldwide rely on the HP-UX operating environment running on HP 9000 and HP Integrity servers. In 2007 HP introduced HP-UX 11i v3, the latest version of HP-UX which came bundled with new features and applications designed to make HP-UX more reliable, robust and easier to deploy and manage. TechWise® Research conducted this current study to determine whether or not v3 is delivering on its promises of increased performance, manageability, and reliability. This paper explores this question by conducting Total Cost of Upgrade (TCU) analyses based on data provided by 130 respondents in 14 different countries.
