| HP-UXHP-UX (Hewlett-Packard UniX) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on UNIX System V (initially System III) and first released in 1984. Recent versions support the HP 9000 series of computer systems, based on the PA-RISC processor architecture, and HP Integrity systems, based on Intel's Itanium architecture. Earlier versions of HP-UX supported the HP Integral PC and 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 offer access control lists for file access permissions as an alternative to 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 integrates VxFS as the primary file system. In 2008 HP-UX 11i was credited with leadership in integrated mission-critical virtualization,[1] observed performance, high availability and manageability.[2] The current shipping release is 11i v3 with the September 2012 update release (the 11th update for HP-UX 11i v3).[3] CharacteristicsSince about 2000 the focus of HP-UX has increasingly been on enhanced reliability, security, workload management, and partitioning. The reliability is provided through single-system quality and self-healing, and in multi-system installations, 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 Serviceguard is the cluster solution for HP-UX. 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 is integrated in HP-UX, with full 'trusted mode' shipping with v3.[4] Features 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. System partitioning (virtualization) ranges from hardware partitions to isolated OS virtual partitions on cell-based servers, and HP Virtual Machines (VMs) on all Integrity servers. HP VMs support guests running on HP-UX 11i v3 hosts - guests can run Linux, Windows, OpenVMS 8.4 or HP-UX. HP supports online VM guest migration, where encryption can secure the guest contents during migration. HP-UX 11i v3 scales as follows: With the acquisition of Compaq in 2001, HP obtained another Unix-based system, Tru64 Unix for AlphaServer hardware platform. HP continues to sell Tru64 UNIX, together with TruCluster software, but discontinued AlphaServer manufacturing in 2007. Release historyPrior 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. 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 HP 9000 Series 800. There may have been a different 2.x version for the Series 200 at an earlier date.
- 3.x (1988)
- HP 9000 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, for example, 3.x was really contemporary with 6.x. The two lines were united at HP-UX 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 HP 9000 Series 300 only. Introduced sockets from 4.3BSD. This version (together with 3.x) also introduced the context dependent files (CDF) feature, 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.[5] CDFs and the CDF filesystem were dropped with release 10.0.
- 7.x (1990)
- Support for HP 9000 Series 300/400, 600/700 (in 7.03) /800 HP systems.[6] Provided OSF/Motif.
- 8.x (January 1991)
- Support for HP 9000 Series 300/400 600/700/800 systems.[6] Shared libraries introduced.
- 9.x (July 1992)
- 9.00, 9.02, 9.04 (Series 600/800), 9.01, 9.03, 9.05, 9.07 (Series 300/400/700), 9.08, 9.09, 9.09+ (Series 700 only), 9.10 (Series 300/400 only). These provided support for the HP 9000 Series 300, 700 and 800 systems. Introduced SAM. The Logical Volume Manager (LVM) was presented in 9.00 for the Series 800 as a replacement for the older methods of disk management. The easiest way 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 HP 9000 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 UNIX System V Release 4 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 also made available for Series 700. 10.0 was followed by 10.01 (1995), 10.02 (1995), 10.03 (1996), 10.08 (1996), 10.09 (1996), 10.10 (1996) and 10.16 (1996).
- 10.20 (1996)
- This release included support for PA-RISC 2.0 processors that support 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.[7]
- 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 1:1 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 HP 9000 V2500 SCA (Scalable Computing Architecture) and V2600 SCA servers. Other versions supported the HP 9000 V-class servers 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 Itanium 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, m:n threads, added more dynamic kernel tunable parameters, and supported HP's Logical Volume Manager on Itanium. 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 Itanium 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 HP-UX 11i v3. This release supports both PA-RISC and Itanium.[8] It was released on February 15, 2007.[9] 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 and Tukwila processors. HP-UX 11i v3 conforms to The Open Group's UNIX 03 standard.[10] Updates for the 11iv3 has been released every 6 months,[11] with the latest being update 10,[12] released in March 2012.
Future versionsIn a 2012 HP-UX 11i roadmap by Hewlett-Packard, it showed plans of continued innovation in HP mission-critical converged infrastructure with on-going updates of HP-UX.[13] HP-UX 11i operating environmentsHP sells HP-UX 11i in Operating Environments (OEs).[14] 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 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)
- Delivers the full HP-UX 11i operating system plus file system and partitioning software and applications for Web serving, system management and security. BOE includes all the software formerly in FOE & TCOE (see below), plus software formerly sold stand-alone (e.g. Auto Port Aggregator).
