GLYPH<SM590000> Improved branch prediction GLYPH<SM590000> Improved co-processor functionality GLYPH<SM590000> IBM Integrated Accelerator for zEnterprise Data Compression (zEDC) (on-chip  compression accelerator) GLYPH<SM590000> Offer a data-centric approach to information (data) security that is simple, transparent, and  consumable (extensive data encryption from inception to archive, in-flight and at-rest). GLYPH<SM590000> Offer a  flexible infrastructure  to concurrently accommodate a wide range of operating  systems and applications, from the traditional systems (for example, z/OS and z/VM) to  the world of Linux, cloud, analytics, and mobile computing. GLYPH<SM590000> Offer state-of-the-art  integration  capability for server consolidation by using virtualization  capabilities in a highly  secure environment : – Logical partitioning, which allows 85 independent logical servers. – z/VM, which can virtualize hundreds to thousands of servers as independently running  virtual machines (guests). – HiperSockets, which implement virtual LANs  between logical partitions (LPARs) within  the system. – Efficient data transfer that uses direct memory access (SMC-D), Remote Direct  Memory Access (SMC-R), and reduced storage access latency for transactional  environments - zHyperLink Express. – The IBM Z Processor Resource/System Manager (PR/SM) is designed for Common  Criteria Evaluation Assurance Level 5+ (EAL 5+) certification for security, so an  application that is running on one partition (LPAR) cannot access another application  on a different partition, which provides essentially the same security as an air-gapped  system. – A new feature was introduced: Secure Exec ution, which not only securely separates  second-level guest operating systems running under KVM for Z from each other but  securely separates access to second-level guests from the hypervisor. GLYPH<SM590000> Offer  high-performance computing  to achieve the outstanding response times that are  required by new workload-type applications. This performance is achieved by  high-frequency, enhanced superscalar processor technology, out-of-order core execution,  large high-speed buffers (cache) and memory, an architecture with multiple complex  instructions, and high-bandwidth channels. GLYPH<SM590000> Offer the  high capacity  and  scalability  that are required by the most demanding  applications, from the single-system and clustered-systems points of view. GLYPH<SM590000> Offer the capability of  concurrent upgrades  for processors, memory, and I/O connectivity,  which prevents system outages in planned situations. GLYPH<SM590000> Implement a system with  high availability  and  reliability.  These goals are achieved with  redundancy of critical elements and sparing components of a single system, and the  clustering technology of the Parallel Sysplex environment. GLYPH<SM590000> Have internal and external  connectivity  offerings, supporting open standards, such as  Gigabit Ethernet (GbE) and Fibre Channel Protocol (FCP). This configuration allows for a logical and virtual server coexistence and maximizes  system utilization and efficiency by sharing hardware resources. It uses 24-, 31-, and 64-bit addressing modes, multiple arithmetic formats, and multiple  address spaces for robust inter-process security. The z15 system design has the following main objectives: Chapter 3. Central processor complex design  91
