Preface
This IBM® Redbooks® publication highlights IBM TS7700 Virtualization Engine Release 3.2 (IBM TS7700). IBM TS7700 is part of a family of IBM System Storage® Enterprise tape products. This book is intended for system architects who want to integrate their storage systems for smoother operation.
The IBM TS7700 offers a modular, scalable, and high-performing architecture for mainframe tape virtualization for the IBM System z® environment. It integrates IBM 3592 tape cartridges, high-performance disks, and a new disk cache subsystem into a storage hierarchy. This storage hierarchy is managed by robust storage management firmware 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
The IBM TS7700 Virtualization Engine offers enhanced statistical reporting. It also includes a standards-based Management Interface (MI) for IBM TS7700 management. The IBM TS7700 Release 3.2 continues the next generation of IBM TS7700 Virtualization Engine servers for System z tape:
•IBM TS7720 features encryption-capable, high-capacity cache using 3 terabyte (TB) serial-attached Small Computer System Interface (SAS) disk drives with Redundant Array of Independent Disks (RAID) 6, providing the ability to scale to very large capacities with the highest level of data protection.
•IBM TS7740 features encryption-capable 600 gigabyte (GB) SAS drives with RAID 6 protection.
Both models write data by policy to physical tape through attachment to high-capacity, high-performance IBM TS1140 and earlier IBM 3592 model tape drives installed in IBM TS3500 tape libraries. Physical tape support is optional on IBM TS7720.
These Virtualization Engines are based on IBM POWER7® technology. They offer improved performance for most System z tape workloads compared to the first generation of IBM TS7700 Virtualization Engine servers.
IBM TS7700 Virtualization Engine Release 3.2 builds on the existing capabilities of the IBM TS7700 family. It also includes the following enhancements to the IBM TS7700 family:
•25 GB logical volume sizes
•Options for attaching back-end physical tape to IBM TS7720 systems
•Up to eight repository partitions in a tape-attached IBM TS7720
Summary of contents
This book contains valuable information about the IBM TS7700 Virtualization Engine for anyone 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 Virtualization Engine. This information is part of this book.
If you have limited knowledge of the IBM TS7700 Virtualization Engine, see the IBM Knowledge Center for TS7700:
If you have more knowledge, a series of technical documents and white papers describing 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:
For a short description of all available technical documents, see “Technical documents on the IBM Techdocs website” on page 932.
Familiarize yourself with the contents of Chapter 1, “Introducing the IBM TS7700 Virtualization Engine” on page 3, Chapter 2, “Architecture, components, and functional characteristics” on page 13, and Chapter 3, “IBM TS7700 usage considerations” on page 97. These chapters provide a functional description of all major features of the product, and they are a prerequisite for understanding the other chapters.
If you are planning for the IBM TS7700 Virtualization Engine, see Chapter 4, “Preinstallation planning and sizing” on page 115. If you already have an IBM TS7700 Virtualization Engine or even an IBM 3494 Virtual Tape Server (VTS) installed, see Chapter 6, “Hardware configurations and upgrade considerations” on page 199. Chapter 5, “IBM TS7700 implementation” on page 183 describes the hardware implementation.
Chapter 5, “IBM TS7700 implementation” on page 183 also describes the major software considerations for the IBM TS7700 Virtualization Engine. For more information about software, see Chapter 4, “Preinstallation planning and sizing” on page 115, and Chapter 7, “Migration” on page 251.
Chapter 8, “Operation” on page 289 provides information about the operational aspects of the IBM TS7700 Virtualization Engine. This information includes the layout of the MI windows to help with daily operational tasks.
If you have a special interest in the performance and monitoring tasks as part of your operational responsibilities, see Chapter 10, “Performance and monitoring” on page 597. 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 related to availability and disaster recovery, see Chapter 11, “Copy Export” on page 697.
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 797, which describes all of the features available for the IBM TS7700 Virtualization Engine.
