Part of the Operating systems glossary:

MPE/iX is the operating system for the line of e3000 midrange business server s from Hewlett-Packard (HP). Its latest version, MPE/iX Version 7.0, is marketed as " Web -enabled" and "Internet-ready." The operating system includes support for Java and HP describes it as providing " OLTP performance and functionality for business-critical applications." Support also is provided for PCI I/O devices. HP emphasizes the value of an operating system that, since its first release in 1972 has built a reputation for being stable, reliable, and robust .

MPE/iX provides support for applications that use standard POSIX C functions. In 2001, HP plans to run MPE-iX on e3000s that use the Intel Itanium ( IA-64 ) microprocessor architecture. MPE originally stood for "Multi-Programming Executive." The "iX" suggests its new support for POSIX (UNIX-compatible) applications and interfaces and a hierarchical file system. Unlike HP's other major operating system, HP-UX (for the HP 9000 server line), MPE/iX supports all the legacy application s that have been written for HP 3000 computers over the years.
