This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM DS8870. The WhitepaperRedpaperbook provides reference information to assist readers who need to plan for, install, and configure the DS8870. The IBM DS8870 is the most advanced model in the IBM DS8000® series and is equipped with IBM POWER7+™ based controllers. Various configuration options are available that scale from dual 2-core systems up to dual 16-core systems with up to 1 TB of cache. The DS8870 features an integrated High-Performance Flash Enclosure (HPFE) with flash cards that can deliver up to 250,000 IOPS and up to 3.4 GBps bandwidth. A High-Performance All-Flash configuration is also available. The DS8870 now features 16 Gbps host adapters. Connectivity options, with up to 128 Fibre Channel/IBM FICON® ports for host connections, make the DS8870 suitable for multiple server environments in open systems and IBM z™ Systems environments. DS8870 Release 7.5 brings new and enhanced IBM z Systems™ synergy features. These features are covered in detail in IBM DS8870 and IBM z Systems Synergy, REDP-5186. The DS8870 supports advanced disaster recovery solutions, business continuity solutions, and thin provisioning. All disk drives in the DS8870 storage system have the Full Disk Encryption (FDE) feature. The DS8870 also can be integrated in a Lightweight Directory Access Protocol (LDAP) infrastructure. The DS8870 can automatically optimize the use of each storage tier, particularly flash drives and flash cards, through the IBM Easy Tier® feature, which is available at no extra charge. This edition applies the IBM DS8870 Release 7.5.

This IBM® Redbooks® publication describes data migrations between IBM DS8000® storage systems, where in most cases one or more older DS8000 models are being replaced by the newer DS8870 model. Most of the migration methods are based on the DS8000 Copy Services. The book includes considerations for solutions such as IBM Tivoli® Productivity Center for Replication and the IBM Geographically Dispersed Parallel Sysplex™ (GDPS®) used in IBM z/OS® environments. Both offerings are primarily designed to enable a disaster recovery using DS8000 Copy Services. In most data migration cases, Tivoli Productivity Center for Replication or GDPS will not directly provide functions for the data migration itself. However, this book explains how to bring the new migrated environment back into the control of GDPS or Tivoli Productivity Center for Replication. In addition to the Copy Services based migrations, the book also covers host-based mirroring techniques, using IBM Transparent Data Migration Facility (TDMF®) for z/OS and the z/OS Dataset Mobility Facility (zDMF).

IBM TotalStorage Productivity Center for Replication Version 3, Release 1 brings support for the advanced copy services capabilities on the DS8000 and DS6000, in addition to the support for ESS model 800 and SVC. This support focuses on automating administration and configuration of these services, operational control (starting, suspending, resuming) copy services tasks and monitoring and managing the copy services sessions. In addition to the support for FlashCopy and Metro Mirror, TotalStorage Productivity Center for Replication V3R1 supports Global Mirror on the ESS800, DS8000, and DS6000 hardware platforms. Advanced disaster recovery functions are also supported with failover/failback (planned and unplanned) from a primary site to a disaster recovery site. TotalStorage Productivity Center for Replication also can monitor the performance of the copy services that provide a measurement of the amount of replication and the amount of time that is required to complete the replication operations. This IBM Redbooks publication provides the information you need to install TotalStorage Productivity Center for Replication, and create and manage replication sessions on AIX. Scenarios are provided that document the work performed in our laboratory setting, using the GUI and CLI.

This IBM Redbooks publication will help you plan, install, and configure the IBM System Storage DS6000 Copy Services functions in System z environments, and provides the details you need to implement and manage these functions. The book includes hints and tips.

This IBM Redbooks publication helps you install, tailor, and configure Copy Services in open systems environments on the IBM System Storage DS6000 storage server series. It should be read in conjunction with the IBM System Storage DS6000 Series: Architecture and Implementation, SG24-6781. This book gives you the details necessary to configure each of the Copy Services functions in an open systems environment. There is a companion book that supports the configuration of the Copy Services functions in a z/OS environment, IBM System Storage DS6000 Series: Copy Services with System z servers, SG24-6782. This book helps you design and create the storage map and install Copy Services in an open systems environment. This book helps you design and create a new Copy Services installation or to migrate from an existing installation, as well as addresses design functions and changes in terminology from other IBM Copy Services products. We include hints and tips to maximize the effective installation. It also includes a section on System i and an overview of the TotalStorage Productivity Center for Replication.

This IBM Redbooks publication will help you to migrate batch VSAM applications to exploit transactional VSAM. DFSMStvs is available in a z/OS environment and offers the ability for VSAM data to be shared for both read and write operations while maintaining integrity and recoverability. DFSNStvs allows logging of changes to recoverable VSAM data sets. Batch programs can use commit and backout functions. This book assumes that you are familiar with the material in the companion book DFSMStvs Overview and Planning, SG24-6971, and refers extensively to material published in that book. We also assume some familiarity with CICS Transaction Server and z/OS. The book is intended for application developers who want to understand how to change applications to make best use of the facilities offered by DFSMStvs and to coexist well with other batch applications and with CICS systems sharing the same VSAM data sets. We assume that you are familiar with the development of batch applications and with the facilities and use of VSAM. The tasks involved in setting up DFSMStvs and the hardware and software prerequisites are not discussed in this book; they are described in DFSMStvs Overview and Planning, SG24-6971.
