IBM Z

IBM's family of 64-bit mainframes, introduced in 2000 as the zSeries. IBM mainframes are robust, mission critical computer systems that run under IBM's z/OS or z/VM operating systems, as well as Linux.

The 21st Century Mainframe
In 2000, IBM's z/Architecture was a major upgrade to the previous ESA/390 mainframes, and the "Z" designation was chosen to reflect zero downtime as models include duplicate parts that take over if the first one fails.

The first Z mainframe was the high-end 900 line, followed in 2002 by the zSeries 800, geared to the mid-size customer. Following is a list of "Z" models over the years. The enterprise class designation refers to high-end machines. See z/OS, zEnterprise, z/Architecture, IBM branding and System/390.

articulated by Chief Information Security Officers and data security experts worldwide, and more than 150 IBM clients around the world who participated and provided feedback in IBM Z's system design over three years.
As a result of this collaboration, IBM Z brings significant advances in cryptography technology, building on a proven encryption platform that safeguards the world's banking, healthcare, government and retail systems.
IBM Z makes it possible, for the first time, for organizations to pervasively encrypt data associated with an entire application, cloud service or database in flight or at rest with one click.
Only IBM Z can protect millions of keys (as well as the process of accessing, generating and recycling them) in "tamper responding" hardware that causes keys to be invalidated at any sign of intrusion and can then be restored in safety.
IBM z/OS Connect technologies can make it easy for cloud developers to discover and call any IBM Z application or data from a cloud service, or for IBM Z developers to call any cloud service.
"The pervasive encryption that is built into, and is designed to extend beyond, the new IBM Z really makes this the first system with an all-encompassing solution to the security threats and breaches we've been witnessing in the past 24 months," said Peter Rutten, analyst at IDC's Servers and Compute Platforms Group.
IBM also announced three groundbreaking new Container Pricing models for IBM Z, providing clients greatly simplified software pricing that combines flexible deployment with competitive economics vs.
IBM Z builds on the capabilities of the world's most powerful transaction engine at the center of global commerce today supporting:
To help financial services organizations more effectively compete in the cloud era, enormous amounts of sensitive data produced by transactions can now be better protected against fraud and cybercrime, analyzed, and monetized using IBM Z -- without causing disruption of day-to-day operations.
The IBM Z, the next generation of IBM's industry-leading CMOS mainframe technology, features the industry's fastest microprocessor, running at 5.2GHz, and a new scalable system structure that delivers up to a 35 percent capacity increase for traditional workloads and up to a 35 percent capacity increase for Linux workloads compared to the previous generation IBM z13.
