This IBM® Redbooks® publication describes the features and functions of the latest member of the IBM Z® platform that was built with the IBM Telum processor: the IBM z16™ (machine type 3931). It includes information about the IBM z16 processor design, I/O innovations, security features, and supported operating systems.

The IBM Z platform is recognized for its security, resiliency, performance, and scale. It is relied on for mission-critical workloads and as an essential element of hybrid cloud infrastructures. The IBM z16 server adds capabilities and value with innovative technologies that are needed to accelerate the digital transformation journey.

The IBM z16 is a state-of-the-art data and transaction system that delivers advanced capabilities, which are vital to any digital transformation. The IBM z16 is designed for enhanced modularity, which is in an industry standard footprint.

This system excels at the following tasks:

  • Providing AI inference with Integrated Accelerator for Artificial Intelligence
  • Making use of multicloud integration services
  • Securing data with pervasive encryption
  • Accelerating digital transformation with agile service delivery
  • Transforming a transactional platform into a data powerhouse
  • Getting more out of the platform with IT Operational Analytics
  • Accelerating digital transformation with agile service delivery
  • Revolutionizing business processes
  • Blending open source and IBM Z technologies

This book explains how this system uses new innovations and traditional IBM Z strengths to satisfy growing demand for cloud, analytics, and open source technologies. With the IBM z16 as the base, applications can run in a trusted, reliable, and secure environment that improves operations and lessens business risk.
