What Does Hewlett-Packard Unix (HP-UX) Mean?

Hewlett-Packard Unix (HP-UX) is an implementation of the Unix operating system that is based on the UNIX System V, developed by Hewlett-Packard and first released in 1984. It was originally developed for HP’s proprietary Integral PC and then made to run on 9000 series business servers. HP-UX was the first Unix-like operating system that offered access control lists as a viable alternative to the standard permissions system of Unix.

HP-UX

HP-UX is a closed source operating system that is provided by HP Enterprise. It is a Unix-like operating system whose design is based on Unix System V. It is basically designed for HP computers. Its target systems is server. It is one of the five commercial operating systems that have versions certified to UNIX 03 standard of The Open Group. The first version of HP-UX was launched in 1983. It has a Monolithic kernel with dynamically loadable modules.

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 monitoring (costs, workload) as well as for logging and visualization. Next to the base version, there is an Enterprise Edition with resource management and the Mission Critical Edition for companies with enterprise-critical applications for the 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 servers, dedicated servers, 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 canceled to 2012, the migration to Itanium HP systems becomes accomplished.

HP-UX 11i version 3 (Release February 2007) offers at an average an 35 percent higher performance on Itanium systems than the previous HP-UX version. Improvements in security management, integrated Multi-Pathing for 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.

Techopedia Explains Hewlett-Packard Unix (HP-UX)

Hewlett-Packard Unix was first released in 1984 on the HP Integral PC as version 1 and version 2 in 1986 on the 9000/500 series of servers utilizing HP FOCUS architecture. It had very strong influences from BSD Unix from the beginning up to version 9.x. Version 10 and onward are closer to System V Unix, with the latest version, 11, catering to more modern concepts such as cluster and cloud computing.

The first version, released in 1984, was nothing more than an embedded ROM version released on the HP Integral PC with the kernel running from the ROM, while other commands ran from the disk. The latest version, which is HP-UX 11i, is geared towards cluster computing, infrastructure as a service (IaaS) and overall cloud computing. It offers operating-system-level virtualization such as hardware partitions, individual OS partitions on cell-based servers and HP virtual machines on Integrity servers.

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.
