The z14 symmetric multiprocessor (SMP) system is the next step in an evolutionary trajectory  that began with the introduction of the IBM System/360 in 1964. Over time, the design was  adapted to the changing requirements that were dictated by the shift toward new types of  applications on which clients depend. z14 servers offer high levels of reliability, availability, serviceability (RAS), resilience, and  security. It fits into the IBM strategy in which mainframes play a central role in creating an  infrastructure for cloud, analytics, and mobile, underpinned by security. The z14 server is  designed so that everything around it, such as operating systems, middleware, storage,  security, and network technologies that support open standards, helps you achieve your  business goals. The modular CPC drawer design aims to reduce, or in some cases even eliminate, planned  and unplanned outages. The design does so by offering concurrent repair, replace, and  upgrade functions for processors, memory, and I/O. For more information about the z14 RAS  features, see Chapter 9, “Reliability, avai lability, and serviceability” on page 363. z14 servers include the following features: It is the next implementation of IBM Z servers to address the ever-changing IT environment. The physical packaging of z14 servers is a continuation and evolution of the z13 systems. Its  modular CPC drawer and single chip module (SCM) design address the augmenting costs  that are related to building systems with ever-increasing capacities. The modular CPC drawer  design is flexible and expandable, offering unprecedented capacity to meet consolidation  needs, and might contain even larger capacities in the future. z14 servers continue the line of mainframe processors that are compatible with an earlier  version. Evolutionfi brings the following processor design enhancements: It uses 24-bit, 31-bit, and 64-bit addressing modes, multiple arithmetic formats, and multiple  address spaces for robust interprocess security. The z14 system design has the following main objectives:
