Abstract

This IBM® Redbooks® publication highlights IBM TS7700 Release 4.0. 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.

The IBM TS7700 offers a modular, scalable, and high-performance architecture for mainframe tape virtualization for the IBM z™ Systems 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


The IBM TS7700 offers enhanced statistical reporting. It also includes a standards-based Management Interface (MI) for IBM TS7700 management. IBM TS7700 R4.0 continues the next generation of IBM TS7700 for z Systems® tape:


  • The IBM TS7760 is an all new hardware refresh and features Encryption Capable, high-capacity cache that uses 4 TB serial-attached Small Computer System Interface (SAS) HDDs in arrays that use dynamic disk pool configuration. This setup can scale to large capacities with the highest level of data protection.
  • Release 4.0 introduces the option to attach to a TS4500 tape library, and to the previous TS3500 tape library, which contains back-end physical tape drives and policies to manage up to eight of the disk repositories in a tape-attached TS7760T. This TS7760T (Tape Attached) configuration mimics the behavior of a TS7740, with additional features that go beyond what a TS7740 can provide.


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 z Systems tape workloads when compared to the previous generations of IBM TS7700.
