Preface Authors This IBMfi Redbooksfi publication describes the new member of the IBM Zfi $^{ }$family, IBM  z14™ Model ZR1 (Machine Type 3907). It includes information about the Z environment and  how it helps integrate data and transactions more securely, and can infuse insight for faster  and more accurate business decisions. The z14 ZR1 is a state-of-the-art data and transaction system that delivers advanced  capabilities, which are vital to any digital transformation. The z14 ZR1 is designed for  enhanced modularity, in an industry standard footprint. A data-centric infrastructure must always be available with a 99.999% or better availability,  have flawless data integrity, and be secured from misuse. It also must be an integrated  infrastructure that can support new applications. Finally, it must have integrated capabilities  that can provide new mobile capabilities with real-time analytics that are delivered by a secure  cloud infrastructure. IBM z14 ZR1 servers are designed with improved scalability, performance, security, resiliency,  availability, and virtualization. The superscalar design allows z14 ZR1 servers to deliver a  record level of capacity over the previous IBM Z platforms. In its maximum configuration, z14  ZR1 is powered by up to 30 client characterizable microprocessors (cores) running at  4.5 GHz. This configuration can run more than 29,000 million instructions per second and up  to 8 TB of client memory. The IBM z14 Model ZR1 is estimated to provide up to 54% more  total system capacity than the IBM z13sfi Model N20. This Redbooks publication provides information about IBM z14 ZR1 and its functions,  features, and associated software support. More information is offered in areas that are  relevant to technical planning. It is intended for systems engineers, consultants, planners, and  anyone who wants to understand the IBM Z servers functions and plan for their usage. It is  not  intended as an introduction to mainframes. Readers are expected to be generally familiar  with IBM Z technology and terminology. This book was produced by a team of specialists from around the world working at the  International Technical Support Organization, Poughkeepsie Center.
