Preface
This IBM® Redbooks® publication covers IBM TS7700 R4.1 through R4.1.2. The IBM TS7700 is part of a family of IBM Enterprise tape products. This book is intended for system architects and storage administrators who want to integrate their storage systems for optimal operation.
This publication explains the all-new hardware that is introduced with IBM TS7700 release R4.1 and the concepts associated with it. TS7700 R4.1 can be installed only on the IBM TS7720, TS7740, and the all-new, hardware-refreshed TS7760 Models. The IBM TS7720T and TS7760T (tape attach) partition mimics the behavior of the previous TS7740, but with higher performance and capacity.
The IBM TS7700 offers a modular, scalable, and high-performance architecture for mainframe tape virtualization for the IBM Z® environment. It is a fully integrated, tiered storage hierarchy of disk and tape. This storage hierarchy is managed by robust storage management microcode with extensive self-management capability. It includes the following advanced functions:
•Policy management to control physical volume pooling
•Cache management
•Redundant copies, including across a grid network
•Copy mode control
TS7700 delivers the following new capabilities:
•7 and 8 way Grid support through approved request for price quotation
•16 Gb IBM FICON® adapter support for TS7760 (R4.1.2)
•Optimized host data compression which is based on software (not FICON adapter hardware) compression algorithm (R4.1.2)
•Control-unit initiated reconfiguration (CUIR) for code load improvement (R4.1.2)
•Grid Resiliency Improvements (R4.1.2)
•System Events Redesign (R4.1.2)
•Remote System Log Processing Support in (R4.1.2)
•Improvements to reliability, availability, and serviceability
The TS7760T writes data by policy to physical tape through attachment to high-capacity, high-performance IBM TS1150 and IBM TS1140 tape drives installed in an IBM TS4500 or TS3500 tape library.
The TS7760 models are based on high-performance and redundant IBM POWER8® technology. They provide improved performance for most IBM Z tape workloads when compared to the previous generations of IBM TS7700.
Summary of contents
This book contains valuable information about the IBM TS7700 for anyone who is interested in this product. The following summary helps you understand the structure of this book, and to decide which of the chapters are of the most interest.
In addition to the material in this book, other IBM publications are available to help you better understand the IBM TS7700.
If you have limited knowledge of the IBM TS7700, see the documentation for TS7700:
A series of technical documents and white papers that describe many aspects of the IBM TS7700 are available. Although the basics of the product are described in this book, more detailed descriptions are provided in these documents. For that reason, most of these detailed record descriptions are not in this book, although you are directed to the appropriate technical document. For these additional technical documents, go to the IBM Techdocs Technical Sales Library website and search for TS7700:
Familiarize yourself with the contents of Chapter 1, “Introducing the IBM TS7700” on page 3, Chapter 2, “Architecture, components, and functional characteristics” on page 15, and Chapter 3, “IBM TS7700 usage considerations” on page 111. These chapters provide a functional description of all of the major features of the product, and they are a prerequisite for understanding the other chapters.
If you are planning for the IBM TS7700, see Chapter 4, “Preinstallation planning and sizing” on page 135 for hardware information. Information on planning for Software begins in 4.3, “Planning for software implementation” on page 171. Chapter 6, “IBM TS7700 implementation” on page 225 describes the implementation and installation tasks to set up an IBM TS7700.
If you already have an IBM TS7700 or even an IBM 3494 Virtual Tape Server (VTS) installed, see Chapter 7, “Hardware configurations and upgrade considerations” on page 243. Chapter 8, “Migration” on page 299 describes migrating to a TS7700 environment.
Chapter 9, “Operation” on page 339 provides information about the operational aspects of the IBM TS7700. This information includes the layout of the MI windows to help with daily operational tasks. Chapter 9 “Host console operations” provides information about commands and procedures that are initiated from the host operating system.
If you have a special interest in the performance and monitoring tasks as part of your operational responsibilities, see Chapter 11, “Performance and monitoring” on page 613. Although this chapter gives a good overview, more information is available in the technical documents on the Techdocs website.
For availability and disaster recovery specialists, and those individuals who are involved in the planning and operation that is related to availability and disaster recovery, see Chapter 12, “Copy Export” on page 735.
Information that is related to disaster recovery can be found in Chapter 5, “Disaster recovery” on page 201 and Chapter 13, “Disaster recovery testing” on page 767.
In addition, the following appendixes conclude this book:
•For information about feature codes and requests for price quotation (RPQ), see Appendix A, “Feature codes and RPQ” on page 805, which lists all of the features available for the IBM TS7700.
•For information about implementation with various IBM systems, such as IBM z/VM®, IBM z/VSE®, the IBM TPF Operations Server, and IBM z/Transaction Processing Facility (IBM z/TPF), see Appendix B, “IBM TS7700 implementation for IBM z/VM, IBM z/VSE, and IBM z/TPF environments” on page 813. This appendix gives a short overview and scheme for the IBM TS7700 implementation.
•For information about job entry subsystem 3 (JES3), an operating system component, see Appendix C, “JES3 examples and information” on page 829. This appendix provides additional information to assist you if you are running an IBM z/OS® system with JES3.
•For information about the layout of a new command that can be helpful with the IBM TS7700 configuration in z/OS, see Appendix D, “DEVSERV QLIB command” on page 849.
•For information about job control language, see Appendix E, “Sample job control language” on page 853, which gives you examples of jobs that are needed for installation and operational tasks.
•For information about categories, see Appendix F, “Library Manager volume categories” on page 877, which gives you a full list of all category codes that are used in both the IBM TS7700 and the IBM 3494 VTS.
•For information about parameters, see Appendix G, “IBM TS7700 parameter examples” on page 887, which provides parameter examples in different grid configurations.
•For information about the input/output definition file (IODF) and the input/output configuration program (IOCP), see Appendix H, “Extra IODF examples” on page 907.
