What is HP-UX 11i Version 1?

With HP-UX 11i, HP delivers a highly available, secure, and manageable operating

system that meets the demands of end-to-end Internet-critical computing. HP-UX 11i

supports enterprise, mission-critical, and technical computing environments. HP-UX 11i

is available on both PA-RISC systems and Itanium

-based systems.

HP-UX 11i version 1 provides new hardware enablement, additional software

functionality, and various HP-UX applications bundled into Operating Environments.

HP-UX 11i version 1 is the recommended next-level enterprise release for all HP-UX

systems currently running HP-UX 10.x or 11.0.

See the HP-UX 11i Installation and Update Guide for information on disk and memory

requirements.

HP-UX 11i Release Names and Release Identifiers

Each HP-UX 11i release has an associated release name and release identifier. The

uname (1) command with the -r option returns the release identifier. The following table

shows the releases available for HP-UX 11i.

Performance Considerations

The performance of HP servers and applications with the HP-UX 11i Operating

Environments is as good or better as compared to HP-UX 11.0 installed in the same

configuration. It must be kept in mind, however, that in the vast majority of cases,

HP-UX is likely to be installed as part of one of the predefined HP-UX 11i Operating

Environments.

The HP-UX 11i Operating Environments provide numerous benefits, including lower

cost as well as simplification of product ordering, installation, integration, and support.

While the HP-UX 11i Operating Environments provide these desirable benefits, they all

involve more software components and daemons than a base HP-UX 11.0 or HP-UX 11i

operating system. Because of this, an Operating Environment may have somewhat

greater system overhead compared to a base operating system installation. This increase

in system overhead, while modest, can nevertheless make it erroneously appear that
