AIX/370 was IBM's fourth attempt to offer Unix-like functionality for their mainframe line, specifically the System/370 (the prior versions were a TSS/370-based Unix system developed jointly with AT&T c.1980, [12] a VM/370-based system named VM/IX developed jointly with Interactive Systems Corporation c.1984, [citation needed] and a VM/370 ...
z/OS UNIX System Services (z/OS UNIX, or informally USS) is a base element of z/OS. [2] z/OS UNIX is a certified UNIX operating system implementation (XPG4 UNIX 95) optimized for mainframe architecture. It is the first UNIX 95 to not be derived from the AT&T source code.
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
IBM 704 mainframe at NACA in 1957. From 1952 into the late 1960s, IBM manufactured and marketed several large computer models, known as the IBM 700/7000 series.The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors.
The zEnterprise is designed to extend mainframe capabilities – management efficiency, dynamic resource allocation, serviceability – to other systems and workloads running on AIX on POWER7, and Microsoft Windows or Linux on x86. [30]
Transaction Processing Facility (TPF) [2] is an IBM real-time operating system for mainframe computers descended from the IBM System/360 family, including zSeries and System z9. TPF delivers fast, high-volume, high-throughput transaction processing, handling large, continuous loads of essentially simple transactions across large, geographically ...
Multiple operating systems are compatible with LPARs, including z/OS, z/VM, z/VSE, and z/TPF on mainframes, AIX and IBM i on IBM Power Systems, and Linux on both. In storage systems, such as the IBM TotalStorage DS8000, LPARs allow for multiple virtual instances of a storage array to exist within a single physical array.
A copy of the mainframe version of AIX or Linux. In the mainframe environment, these operating systems often run under VM, and are handled like other guest operating systems. (They can also run as 'native' operating systems on the bare hardware.) There was also the short-lived IX/370, as well as S/370 and S/390 versions of AIX (AIX/370 and AIX ...
