In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family now includes the newest model, the IBM z17, as well as the z16, z15, z14, and z13 (released under the IBM z Systems/IBM System z names), the IBM zEnterprise models (in common use the zEC12 and z196), the IBM System ...
The z14 is a microprocessor made by IBM for their z14 mainframe computers, announced on July 17, 2017. [ 2 ] [ 4 ] Manufactured at GlobalFoundries ' East Fishkill, New York fabrication plant. [ 1 ] IBM stated that it is the world's fastest microprocessor by clock rate at 5.2 GHz, [ 2 ] with a 10% increased performance per core and 30% for the ...
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 collaborated with IBM on the z900-G2/z800 CPUs introduced in 2002, Hitachi's machines are not z/Architecture-compatible.
IBM's Poughkeepsie site is where the z16 mainframe is tested and manufactured, continuing a six-decade history of mainframes at the site.
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. A pair of IBM mainframes. On the left is the IBM z Systems z13. On the right is the IBM LinuxONE Rockhopper. An IBM System z9 mainframe
The cache (e.g. level 3) is doubled from the previous generation z14, while the "L4 cache increased from 672MB to 960MB, or +43%" with the new add-on chip system controller (SC) SCM. Both it and all levels of cache in the main processor from level 1 use eDRAM, instead of the traditionally used SRAM. "A five-CPC drawer system has 4800 MB (5 x ...
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 ...
The HMC is a PC connected to the mainframe and emulates the Support Element. All preceding zSeries mainframes used a modified version of OS/2 with custom software to provide the interface. System z9's HMC no longer uses OS/2, but instead uses a modified version of Linux with an OS/2 lookalike interface to ease transition as well as a new interface.
