HP-UX

HP-UX is based on the UNIX System V Release 4 and was designed by HP for the RISC architecture of Motorola. It is a pure server operating system with high availability and flexible memory and security management.

HP-UX is equipped with a variety of tools for use in enterprises for the monitoring (costs, work load) as well as for the logging and visualization. Next to the base version there is a Enterprise Edition with resource management and the Mission Critical Edition for companies with enterprise critical applications for highest availability and security. This operating system has a built-in host intrusion detection (H-IDS). This operating system is used for content servers, web server, dedicated server, databases or also for cluster systems.
The VUE (Visual User Environment) and CDE are available as a GUI, the last named is the standard GUI since the HP-UX version 10.20. HP develops HP-UX 11i version 4 and plans HP-UX 11i version 5 as a longer-term goal. HP-UX 11i version 3 still shall be ready in autumn 2006. The PA-RISC platform shall be cancelled to 2012, the migration to Itanium HP systems becomes accomplished.

HP-UX 11i version 3 (Release February, 2007) offers at average an 35 percent higher performance on Itanium systems than the previous HP-UX version. Improvements in the security management, integrated Multi-Pathing for the access to the same storage system with redundant controllers and the parallel use of HP certified operating systems are part of the innovations. A combined cluster can be created with the help of the Serviceguard and Integrity Virtual Machines. HP-UX can adress 100 Petabyte (100,000 TByte) of memory.

Tru64 UNIX

This UNIX derivative of the company DIGITAL was developed for the alpha platform. Originally it resulted from the operating system OSF/1 out and is also called DUNIX (DIGITAL UNIX). It is used on alpha servers and HP TruCluster servers. Tru64 UNIX was certified for the security level C2 and supports ACL.

OpenVMS

VMS (Virtual Memory System) was designed in 1976 especially for 32-bit computers and used on VAX computer as well as the PDP-11. There also is a 64-bit version of the operating system for alpha systems. DIGITAL (DEC, Digital Equipment Corporation) were founded by Ken Olsen on 25. Octobers 1977. PDP system as well as the VAX and VMS architecture lasts never developed without DIGITAL. It is used for mainframes, servers and clusters and in the desktop area too. With Ultrix DIGITAL had a BSD based UNIX. In the 80s DIGITAL has placed itself as No.2 behind IBM. OpenVMS is used at most in the application area of health service, CPU production, stock exchanges and lotteries. 1996 were counted about 500,000 installations with OpenVMS. The complete technology was taken by Compaq in 1998, HP took the company Compaq and thus also OpenVMS in 2002.
