HP-UX
HP-UX (from "Hewlett Packard Unix") is a discontinued proprietary implementation of the Unix operating system developed by Hewlett Packard Enterprise, now out of standard support (Mature Support on HPE Integrity without Sustaining Engineering through at least 2028); the final versions support HPE Integrity Servers, based on Intel's Itanium architecture. It is based on Unix System V (initially System III) and first released in 1984.
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, the HP 9000 Series 500 computers based on HP's proprietary FOCUS architecture, and later HP 9000 Series models based on HP's PA-RISC instruction set 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.[citation needed] HP-UX was also among the first Unix systems to include a built-in logical volume manager.[citation needed]
Following the discontinuation of Itanium processors, support for HP-UX ended on December 31, 2025. HP-UX 11i (the latest then-supported version) is certified to The Open Group's older UNIX 03 standard. Previous releases were certified to the UNIX 95 standard.
HP-UX 11i offers a common shared disks 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.
HP-UX offers operating system-level virtualization features such as hardware partitions, isolated OS virtual partitions on cell-based servers, and HP Integrity Virtual Machines (HPVM) on all Integrity servers. HPVM supports guests running on HP-UX 11i v3 hosts – guests can run Linux, Windows Server, OpenVMS 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 (on a SuperDome 2 with 32 Intel Itanium 9560 processors):
The 11i v2 release introduced kernel-based intrusion detection, strong random number generation, stack buffer overflow protection, security partitioning, role-based access management, and various open-source security tools.
HP classifies the operating system's security features into three categories: data, system and identity:
