On April 8, 2014, in honor of the 50th anniversary of the System/360 mainframe, IBM announced [23] the release of its first converged infrastructure solution based on mainframe technology. Dubbed the IBM Enterprise Cloud System, [ 24 ] this new offering combines IBM mainframe hardware, software, and storage into a single system and is designed ...
The IBM System z Application Assist Processor (zAAP), previously known as the zSeries Application Assist Processor, is a mainframe processor introduced by IBM in 2004. zAAP engines [1] are dedicated to running specific Java and XML workloads under z/OS, accelerating performance. zAAPs are available for zSeries 990 and 890 servers and later zSeries and zEnterprise models.
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 ...
Linux on IBM Z or Linux on zSystems is the collective term for the Linux operating system compiled to run on IBM mainframes, especially IBM Z / IBM zSystems and IBM LinuxONE servers. Similar terms which imply the same meaning are Linux/390 , Linux/390x, etc.
IBM bought PSI in July 2008, and the PSI systems are no longer available. [41] FLEX-ES, zPDT and the Hercules emulator also implement z/Architecture. Hitachi mainframes running newer releases of the VOS3 operating system implement ESA/390 plus Hitachi-unique CPU instructions, including a few 64-bit instructions. While Hitachi formally ...
An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
IBM stated that it is the world's fastest microprocessor and is about 10% faster than its predecessor the zEC12 in general single-threaded computing, [3] but significantly more when doing specialized tasks. [4] The IBM z13 is the last z Systems server to support running an operating system in ESA/390 architecture mode. [5]
A single-frame IBM z15 mainframe. Larger capacity models can have up to four total frames. This model has blue accents, as compared with the LinuxONE III model with orange highlights. The processor unit chip (PU chip) has 12 cores. The z15 cores support two-way simultaneous multithreading. [3]
