Among all Unix based operating systems, HP-UX is the one, which is widely used  on Hewlett-Packard (HP) computers.  HP engineers designed and developed this proprietary implementation of Unix, which was released in 1984. The early versions of HP-UX were designed to run on Motorola 68000 processor based HP Integral PC and FOCUS processor based HP 9000 series computer systems. The latest versions support the Intel’s Itanium architecture based HP Integrity and PA-RISC  architecture based HP 9000 series computer systems. HP-UX has some unique features which the other Unix based operating systems do not have. One of such features is access control list, which is required for file access permissions. Built-in logical volume manager is another example.

Brief History

The first version, i.e. HP-UX 1.0 was released in 1984. The basic kernel software used to be programmed into the Read Only Memory or ROM. That is why it was also known as embedded ROM version. Other commands were executed from disk. Since then, several versions have been released regularly with new and improved features. The latest version is HP-UX 11i v3 which was launched on 15th February,2007. It runs on PA-RISC and Itanium based HP computer systems. Some of the new features are Integrity Virtual Machine, multi volume Veritas file system, Veritas cluster file system, unified file cache, etc. Updates for HP-UX 11i v3 have been released at regular intervals. In march 2012, the latest update was released.

Features

The designers of HP-UX have always focused on security, reliability, partitioning and workload management. Reliability has been improved considerably through error diagnosis and rectification. The clustered file system is supported by a single root disk. To improve the performance, workload is controlled by HP Global Workload Management system. The security system of HP-UX is quite robust. In the version of 11i v2,new security features, such as role based access management, security partitioning, stack buffer overflow protection, effective random number generation, kernel based intrusion detection and other security tools have been added. This features enhanced the security system considerably. System partitioning, which is also known as operating system level virtualization, is  achieved by hardware partitioning and isolated operating system virtual partitions. The memory partitioning should be done very carefully with the help of an experienced Computer support provider.

Hardware

HP-UX has been designed for Motorola 680×0 processor based HP 9000/300,HP Focus and HP PA-RISC computer systems. Initially, HP-UX was developed to run on HP 9000/500 system. Later, it was upgraded to support HP 9000/300 and HP 9000/400 computer systems. Versions earlier than 11.00 were designed as 32 bit system and the latter versions supported 64 bit systems. For highly efficient operations, the proper hardware should be selected for a particular HP-UX version with the assistance of a HP support provider.

Supported File Systems

Along with a very flexible and simple file systems, HP-UX also provides very effective volume management tools which allow the user to manage the environment dynamically. Apart from that, expanding file system, adding new hardware components and creating virtual volumes have become much easier, compared to other operating systems. Veritas File System or VxFS is supported by HP-UX. The files systems which could be read, written and formatted by HP-UX are jfs, hfs and lif formats. Other than these formats, FAT, UFS, BFFS and NFS file formats could also be read and written.

Network Support For HP-UX

HP Support providers render extensive services for HP-UX problems. Apart from that, many third party vendors provide excellent Computer support to the HP-UX users.
