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 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.
