IBM Virtualization Engine TS7700 with R3.1

An IBM Redbooks publication

Note: A new draft version of this publication is now available


This IBM® Redbooks® publication highlights TS7700 Virtualization Engine Release 3.1. It is intended for system architects who want to integrate their storage systems for smoother operation. The IBM Virtualization Engine TS7700 offers a modular, scalable, and high-performing architecture for mainframe tape virtualization for the IBM System z® environment. It integrates 3592 Tape Drives, 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 TS7700 Virtualization Engine offers enhanced statistical reporting. It also includes a standards-based management interface for TS7700 Virtualization Engine management.

The new IBM Virtualization Engine TS7700 Release 3.1 continues the next generation of TS7700 Virtualization Engine servers for System z tape:

  • IBM Virtualization Engine TS7720 Server Model VEB with 3956-CS9 and 3-TB SAS drives with RAID 6 protection
  • IBM Virtualization Engine TS7740 Server Model V07 with 3956-CC9 with 600-GB SAS drives with RAID 6 protection

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 TS7700 Virtualization Engine servers.

TS7700 Virtualization Engine Release 3.1 builds on the existing capabilities of the TS7700 family. It also introduces the following capabilities:

  • 8-Gb IBM FICON® adapters for host attachment
  • Up to eight FICON channel host attachments, doubling the previous number of channels available
  • Up to 512 logical path definitions per FICON channel, doubling the previous number of logical paths per channel
  • IBM FlashCopy® for disaster recovery testing
  • Support for a second TS7720 expansion frame attached to a TS7720 system for a total TS7720 system capacity up to 1 PB before compression
  • New Time Delayed Copy policy
