HP-UX (singkatan dari Hewlett-Packard Unix) adalah salah satu sistem operasi keluarga UNIX yang diimplementasikan oleh Hewlett-Packard yang banyak digunakan di komputer mainframe. HP-UX dibuat berdasarkan sistem UNIX System V (meski pada awalnya adalah UNIX System III). Sistem operasi ini berjalan di atas jajaran prosesor HP PA-RISC dan keluarga Intel Itanium (karena memang Intel dan Hewlett-Packard bekerja sama dalam mengembangkan Itanium), dan juga kemudian dapat berjalan di atas sistem Apollo/Domain. Sistem-sistem versi terdahulu bahkan dapat berjalan di atas komputer HP 9000 Series 200, 300 dan 400 yang menggunakan prosesor Motorola 68000 series, dan juga HP 9000 Series 500 yang menggunakan prosesor dengan arsitektur HP FOCUS.
HP-UX merupakan versi UNIX pertama yang menerapkan fungsi access control list untuk izin akses berkas dibandingkan dengan izin akses UNIX yang biasa digunakan. HP-UX juga merupakan salah satu sistem UNIX pertama yang mengintegrasikan Logical Volume Manager (LVM). HP juga memiliki kerjasama dengan VERITAS, sehingga mereka menggunakan sistem berkas VxFS sebagai sistem berkas utamanya. Meskipun demikian, karena berbagai sebab, sistem berkas yang digunakan sebagai perangkat booting tetap menggunakan Hi Performance File System (HFS).
Hingga rilis HP-UX 11i versi 2, sistem operasi ini dapat mendukung:
128 prosesor (dapat diperluas hingga 256 prosesor)
1 Terabyte memori utama
32 Terabyte maksimum ukuran sistem berkas
2 Terabyte ukuran berkas maksimum
[sunting] Sejarah
Versi HP-UX pertama adalah HP-UX 1.0 yang dibangun pada tahun 1983. Sistem operasi tersebut dibuat berbasiskan UNIX System III dan kemudian UNIX System V.
HP-UX pertama, yang ditujukan untuk sistem FOCUS (komputer HP seri 500) menggunakan kernel yang ditulis dengan menggunakan bahasa MODCAL (sebuah bahasa pemrograman Pascal yang dimodifikasi dengan tambahan pemrograman tingkat rendah). Pascal/Modcal pun menjadi bahasa utama untuk pengembangan sistem operasi HP pada awal dekade 1980-an hingga pertengahan 1980-an. Kernel ini pun diletakkan di atas level lebih rendah dibandingkan kernel yang disebut SUNOS (tidak ada korelasi dibandingkan dengan SunOS, sistem operasi UNIX milik Sun Microsystems) dan sistem berkas yang diemulasikan yang mirip dengan UFS yang berjalan di atas sistem berkas HP-peculiar, yang disebut Structured Directory Format. Pada komputer HP Seri 200 dan 300, HP-UX pada awalnya menggunakan sistem UNIX System III, sebelum kemudian menggunakan UNIX System V. ROM HP-UX untuk HP Integral PC memiliki dua versi, yakni versi 1.0 yang merupakan HP-UX yang berbasiskan UNIX System III dan versi 5.0 yang merupakan HP-UX yang berbasis UNIX System V.
HP pun kemudian merilis arsitektur RISC miliknya, yang disebut sebagai HP Precission Architecture Reduced Instruction Set Computing (disingkat PA-RISC) pada semester kedua tahun 1986, dan digunakan pada dua buah jajaran komputer, yakni HP3000 series 930 (yang memiliki persamaan dengan HP 9000 series 840) dan HP3000 series 950 (yang memiliki persamaan dengan HP9000 8xx). Tidak seperti sistem-sistem PA-RISC yang terbaru, pada 3000/930 dan 9000/840, prosesor PA-RISC disebarluaskan melalui beberapa papan Transistor-to-Transistor Logic (TTL).
Pada waktu itu, HP tidak memiliki jumlah perangkat keras yang mencukupi untuk dikirimkan kepada pengguna, tapi memiliki beberapa perangkat keras yang diinstal dalam beberapa tempat pengembangan pihak ketiga.

HP-UX (Hewlett Packard UniX) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on System V (initially System III). It runs on the HP 9000 PA-RISC-based range of processors and HP Integrity Intel's Itanium-based systems, and was also available for later Apollo/Domain systems. Earlier versions also ran on the HP 9000 Series 200, 300, and 400 computer systems based on the Motorola 68000 series of processors, as well as the HP 9000 Series 500 computers based on HP's proprietary FOCUS processor architecture.
HP-UX was the first Unix to use access control lists for file access permissions rather than the standard Unix permissions system. HP-UX was also among the first Unix systems to include a built-in logical volume manager. HP has had a long partnership with Veritas Software, and uses VxFS as the primary file system. HP-UX 11i is currently credited with leadership in integrated mission-critical virtualization[1] , observed performance, high availability and manageability.[2]
The current shipping release is HP-UX 11i v3 (11.31) with Update 4 (0903).

[edit] Characteristics
Since about 2000 the focus of HP-UX has increasingly been on enhanced reliability, security, workload management, and partitioning. The reliability is provided through clustering technology and application failover on a system outage, as well as error monitoring and correction. HP-UX 11i offers a common root disk for its clustered file system. HP provides HP Serviceguard as the clustering solution for HP-UX 11i, as well as for Linux. HP Global Workload Management adjusts workloads to optimize performance, and integrates with Instant Capacity on Demand so installed resources can be paid for in 30-minute increments as needed for peak workload demands.
Security features have significantly increased with 11i v2, with the addition of kernel-based intrusion detection, strong random number generation, stack buffer overflow protection, security partitioning, role-based access management, and various open source security tools. The system partitioning (virtualization) ranges from hardware partitions to isolated OS virtual partitions, and most recently the Virtual Server Environment (VSE).
HP-UX 11i v3 scales as follows:
128 processor cores
2 TB main memory
32 TB maximum file system
16 TB maximum file size
100 million ZB storage
With the acquisition of Compaq in 2001, HP obtained another Unix-based system, the Tru64 for AlphaServer hardware platform. HP continues to sell Tru64 UNIX, together with TruCluster software, but discontinued AlphaServer manufacturing in 2007.
[edit] Release history
Prior to the release of HP-UX version 11.11, HP used a decimal version numbering scheme with the first number giving the major release and the number following the decimal showing the minor release. With 11.11, HP made a marketing decision to name their releases 11i followed by a v(decimal-number) for the version. The i was intended to indicate the OS is Internet-enabled, but the effective result was a dual version-numbering scheme. The name change was apparently made to pay homage to the World War I Armistice anniversary,[citation needed] which occurs on 11.11 in nations that use decimal dates.
[edit] Versions
1.0 (1984)
Support for the HP Integral PC (embedded ROM version)basic kernel runs from ROM other commands are disk based.
2.0 (1987)
First release for series 800. There may have been a different 2.x version for series 200 at an earlier date.
3.x (1988)
Series 600/800 only. Note: 2.x/3.x (for series 600/800) were developed in parallel with 5.x/6.x (for series 200/300/400), so, e.g., 3.x was really contemporary with 6.x. The two lines were united at 7.x (with different minor numbers for different series), so that series 800 jumped from 3.1 to 7.0 and series 300 from 6.5 to 7.01.
5.0 (1985)
Updated and renamed HP-UX 1.0 for the HP Integral PC. Supported series 200, 300 and 500.
6.x (1988)
Support for 300 series only. Introduced sockets from 4.3BSD. This version (together with 3.x) also introduced a feature of context dependent files (CDF), a method of allowing a fileserver to serve different configurations and binaries (and even architectures) to different client machines in a heterogeneous environment. A directory containing such files had its suid bit set and was made hidden from both ordinary and root processes under normal use. Such a scheme was sometimes exploited by hackers to hide exploits.[3] CDF's and the CDF filesystem were dropped with release 10.0.
7.x (1990)
Support for 300/400, 600/700 (in 7.03) /800 HP systems.[4] Provided OSF/Motif.
8.x (January 1991)
Support for 300/400 600/700/800 HP systems.[4] Shared libraries introduced.
9.x (July 1992?1995)
9.00, 9.02, 9.04 (s600/s800), 9.01, 9.03, 9.05, 9.07 (s300/s400/s700), 9.08 (s700), 9.09 (s700), 9.09+ (s700), 9.10 (s300/s400 only). These provided support for the series 300, 700 and 800 HP systems. Introduced SAM.The Logical Volume Manager (LVM) was presented at 9.00 for s800 as a replacement for the older methods of disk management. The easiest was to determine the platform that a version of HP-UX 9.x would run on was by the last digit. Even numbers ran on servers, odd numbers ran on workstations.
10.0 (1995)
This major release saw a convergence of the operating system between the series 700 (workstation) and series 800 (server) systems. (The OS no longer supported the older series.) There was also a significant change in the layout in the system files and directories, based on the AT&T SVR4 UNIX standard. Applications were removed from /usr and moved under /opt; startup configuration files were placed under /etc/rc.config.d; users were moved to /home from /users. Software for HP-UX was now packaged, shipped, installed, and removed via the Software Distributor (SD) tools. LVM was made available for s700, too.
10.01 (1995)
10.02 (1995)
10.03 (1996)
10.08 (1996)
10.09 (1996)
10.10 (1996)
10.16 (1996)
10.20 (1996)
This release included support for PA-RISC processors that support PA2.0, including 64-bit data registers. Pluggable Authentication Modules (PAM) were introduced for use within CDE. The root file system could be configured to use the Veritas File System (VxFS). For legacy as well as technical reasons, the file system used for the boot kernel remained Hi Performance FileSystem (HPFS; a variant of UFS) until version 11.23. 10.20 also supported 32-bit user and group identifiers. The prior limit was 60,000, or 16-bit. This and earlier releases of HP-UX are now effectively obsolete, and support by HP ended on June 30, 2003.
10.24
This is a Virtual Vault release of HP-UX, providing enhanced security features. Virtual Vault is a compartmentalised operating system in which each file is assigned a compartment and processes only have access to files in the appropriate compartment and unlike most other UNIX systems the superuser (or root) does not have complete access to the system without following correct procedures.
10.30 (1997)
This was primarily a developer release with various incremental enhancements. The use of PAM continued to expand in the system security components. Various changes to system calls were also made. This OS also provided the first support for Kernel Threads, with a 1x1 thread model (each user thread is bound to one kernel thread). 10.30 was also the first release of HP-UX that was fully year 2000 compliant.
11.00 (1997)
The first HP-UX release to also support 64-bit addressing; previous releases had been 32-bit only. It could still run 32-bit applications on a 64-bit system. This release was also deemed Y2K-compliant. It supported 1×1 kernel threads, symmetric multiprocessing, fibre channel, and NFS PV3. It also included tools and documentation to convert 32-bit code to 64-bit.
11.04
Virtual Vault release.
11.10
This was a limited release to support the V2500 SCA (Scalable Computing Architecture) and V2600 SCA servers. Other versions supported the V-class server in a single cabinet configuration, 11.10 ran on the SCA versions where two servers are stacked on top of each other, interconnected by a hyperplane crossbar. 11.10 also added JFS 3.3, 128-CPU support, AutoFS, and a new ftpd. It was not available separately.
11.11 (2000)
Also known as 11i, this release of HP-UX introduced the concept of Operating Environments. It was released in December, 2000. These are bundled groups of layered applications intended for use with a general category of usage. The available types were the Mission Critical, Enterprise, Internet, Technical Computing, and Minimal Technical OEs. (The last two were intended for HP 9000 workstations.) The main enhancements with this release were support for hard partitions, gigabit ethernet, NFS over TCP/IP, Loadable Kernel Modules, dynamic kernel tunable parameters, kernel event Notifications, and protected stacks.
11.20 (2001)
Also known as 11i v1.5, this release of HP-UX was the first to support the new line of Itanium-based (IA-64) systems. It was not intended for mission critical computing environments and did not support HP's ServiceGuard cluster software. It did provide support for running PA-RISC compiled applications on IA-64 systems, and for Veritas Volume Manager 3.1.
11.22 (2002)
An incremental release of the Itanium version of HP-UX, it was designated 11i v1.6. This version achieved 64-way scalability, MxN threads, added more dynamic kernel tunable parameters, and supported HP's Logical Volume Manager on IA-64. It was built from the 11i v1 source code stream.
11.23 (2003)
The original release of this version was in September 2003 to support the Itanium-based systems. This version is also identified as 11i v2. In September 2004 the OS was updated to provide support for both Itanium and PA-RISC systems. Besides running on IA-64 systems, this release includes support for ccNUMA, web-based kernel and device configuration, IPv6 and a strong random number generation.
11.31 (2007)
This release is also identified as 11i v3. This release supports both PA-RISC and IA-64.[5] It was released on February 15, 2007.[6] Major new features include native multipathing support, a unified file cache, NFS v4, Veritas ClusterFS, multi-volume VxFS, and integrated virtualization. Hyperthreading is supported on Itanium systems with Montecito processors. HP-UX 11i v3 conforms to the The Open Group's UNIX 03 standard.[7]
[edit] Earlier history
The first version of HP-UX was 1.0, built about 1983. It started out based on System III Unix, and later on System V.
The first HP-UX, for the FOCUS systems (Series 500s), had a kernel written in MODCAL, a modified Pascal with extensions for low-level programming. Pascal/MODCAL was in vogue at HP for operating system work in the early-to-mid 1980s. This kernel in turn was hosted on top of another lower-level kernel called SUNOS (no relation to Sun Microsystems' SunOS) and emulated a file system similar to UFS on top of an HP-peculiar filesystem called Structured Directory Format (which led to curious features like . and .. not actually existing in a directory as opened and read). The userland was a mix of AT&T, UCB, and HP sources.
The series 200/300 history also started out claiming System III and later System V. The HP-UX ROMs for the HP Integral PC had two versions: 1.0 which was System III based and 5.0 which was System V based.
HP announced its Precision Architecture in the second half of 1986, for two hardware lines: the HP3000 series 930 which had an equivalent HP9000 series 840, and the HP3000 series 950 which also had an HP9000 series 8xx equivalent. Unlike later PA-RISC systems, in the 3000/930 and 9000/840, the PA-RISC processor was spread across several boards of TTL.
At the time, HP did not have shippable quantities of hardware, but did have some installed at third-party developers sites. It was another year before MPE/XL was ready for its 1.0 release to customers, and in that time the HP9000 series 840 had shipped with HP-UX and the HP3000 series 930 had been dropped from the price list, not being enough faster than a classic HP3000 series 70 running a similar workload.
When it came time to do a Unix for the first PA-RISC systems (Series 800), at least the kernel was based on 4BSD but then worked over to make it behave more like System V and other HP-UXs. BSD-isms gradually got put back into it over the late 1980s and 1990s. That is, HP started a fresh port of Unix and then layered the old code and APIs on top.
The last release for the series 500 was 5.2.
Series 200 and Series 800 HP-UXs started with versions 1.0 and later got version number bumps up to other ports' version numbers as they became more compatible with those ports. So s200 went from 2.x to 5.0 when it got demand paging and more compatible with s500 5.0, and PA-RISC went from 3.1 to 7.0 when its userland was being built from common sources used in 7.0 on the s300.
By HP-UX 7 even the series 300 port was feeling somewhat BSDish, including the BSD Fast File System and a filesystem with long filenames.
Kernel had common source (across series 700/800 at least, maybe s300/400 too) in 8.0.
[edit] Operating environments
HP sells HP-UX 11i in Operating Environments (OEs). OEs are HP-tested and integrated operating system plus application bundles designed to simplify installation and maintenance while providing the functionality needed for the system's purpose.
In 2008, HP introduced new OEs for HP-UX 11i v3 to align application bundles with today's typical systems' use. OEs for HP-UX 11i v2 remain unchanged. The following lists the currently available HP-UX 11i v3 OEs:
HP-UX 11i v3 Base OE (BOE)
