These innovations can help you create new applications while providing opportunities to optimize qualities of service for competitive advantage. IBM Systems z Systems Data Sheet z/ OS V2.2 Helps You Transform to the Era of Digital Business Enterprises are embarking on a digital transformation to synthesize data to more effectively compete in today’s economy. z/OS availability They are changing the way they assimilate, process, and deliver security information to workforces, customers, and business partners. scalability Companies must also support exceptional SLAs for traditional workloads while developing innovative mobile and social applications. Indeed most cloud and mobile transactions use core enterprise data on z Systems; it is estimated that over 70 percent of business transactions touch the mainframe at some point. The enhancements in z/OS V2.2 help you process huge amounts of data securely, analyze it to gain insight quickly to support mobile clients. IBM z/O S V2.2 leverages the IBM z13 capabilities ●●●Customers can gain outstanding qualities of service with z/ OS V2.2, which offers support for the IBM z13, IBM zEnterprise® EC12, zBC12, z196, and z114, as well as System z10® Enterprise Class and z10 BC servers. ●●●z/OS V2.2 supports up 85 LPARS on a single server with z13, a 40 percent increase over 60 LPARS on a single server with zEC12 (30 LPARS with zBC12). ●●●Support for the new vector extension facility (SIMD) instruc- ●●●Support for up to 4 TB of maximum available RAIM memory tions is available on z13 servers.

Extended format BSAM/QSAM sequential data, DFSMSdss™ and DFSMShsm™, Java 8 workloads and SMF log data can all benefit from zEDC compression. ●●●Support for the SMC-R protocol that uses RoCE (RDMA over converged Ethernet), designed for low latency, high- bandwidth communications. SMC-R (Shared Memory Communications-RDMA) is application transparent, and can be used without requiring any changes to applications code. SMC-R allows existing TCP/IP applications to quickly and efficiently transfer data between z/OS hosts. Now the RoCE adapter, the PCIe card, can be shared to support up to 31 z/OS images on the z13 for improved cost efficiencies. IBM z13 3 IBM Systems z Systems Data Sheet Drive Data Transformation and Analytics The strength of z/OS in managing and delivering huge volumes of data has established IBM z Systems as the ideal platform for data serving applications. Businesses running transactional and batch applications on z/OS value traditional high availability, scale, and security, while enjoying the freedom to run z/OS seamlessly alongside new mobile, social and other workloads. The ability to run new applications in close proximity to data gives you the business performance and the agility you need while providing easier integration with your core applications. z/OS V2.2 features many capabilities to allow you to capture the value of your transactional and operational data by strengthening the capabilities of batch processing, transaction processing, support for IBM z13 enhancements in the input/ output (I/O) subsystem and more.
