In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family will soon include 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 ...
The Processor Unit chip (PU chip) has an area of 696 mm 2 (25.3 × 27.5 mm) and consists of 6.1 billion transistors. [3] It is fabricated using GlobalFoundries' 14 nm FinFET silicon on insulator fabrication process, using 17 layers of metal and supporting speeds of 5.2 GHz, which is higher than its predecessor, the z13.

The IBM z13 is the last z Systems server to support running an operating system in ESA/390 architecture mode. [2] However, all 24-bit and 31-bit problem-state application programs originally written to run on the ESA/390 architecture will be unaffected by this change.
IBM introduced what it says is the world's first 2-nanometer chipmaking technology. ... each generation of computer chips got faster and more power-efficient because their most basic building ...
In fact, Fujitsu/Amdahl now sells used IBM mainframes and offers services to migrate customers to the IBM machines (This migration is straightforward and comparable to upgrading from one IBM model to a newer IBM model). The IBM z13 is the last z Systems server to support running an operating system in ESA/390 architecture mode; [21] z14, and ...
New in z15 is an on-chip nest accelerator unit, shared by all cores, to accelerate compression. [3] 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.
HASP was developed by IBM Federal Systems Division contractors at the Johnson Space Center in Houston. [2] [3] It originally managed job scheduling and print and punch output for a single OS/360 computer. Multi Access Spool capability was added to let peer computers share a common job queue and print/punch output queues. [citation needed]
