In 1986, IBM introduced AIX Version 1 for the IBM RT PC workstation. It was based on UNIX System V Releases 1 and 2, incorporating source code from 4.2 and 4.3 BSD UNIX. [14] AIX Version 2 followed in 1987 for the RT PC. [15] In 1990, AIX Version 3 was released for the POWER-based RS/6000 platform. [16]
IBM announced the System/360 (S/360) line of mainframes in April 1964. [4] The System/360 was a single series of compatible models for both commercial and scientific use. The number " 360 " suggested a "360 degree ," or "all-around" computer system.
A pair of IBM mainframes. On the left is the IBM z13 (while the naming was changed, the z13 line had a zSystems label on doors). On the right is the IBM LinuxONE Rockhopper. IBM Z [1] is a family name used by IBM for all of its z/Architecture mainframe computers.
International Business Machines (IBM) used to dominate the computer industry -- especially in the 1960s when mainframe computers were the only game in town. During the 1970s, that dominance gave ...
[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. Through integration with the rest of z/OS, additional Time Sharing Option (TSO) commands are available alongside the usual UNIX services, making it possible ...
IBM next-gen mainframe will be powered by the Telum II processor. Each chip features eight CPU cores, a large pool of fast cache memory, and a built-in AI accelerator meant for inferencing workloads.
An IBM System z9 mainframe. 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.
Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM mainframe-compatible systems which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space.
