  • Proactively monitor archived data with policy-based media verification
  • Strengthen security and compliance with encryption and WORM media
  • Simplify user access to data stored on tape via IBM Spectrum Archive
  • Provide a flexible upgrade path to expand tape storage as needs grow
  • Reduce the storage footprint and simplify cabling with 10U of rack space

IBM TS4500 tape library

Big data offers vast opportunities for business insight, but you need the right technology to help you manage and use that data. IBM cloud solutions can help you harness the power of big data while reducing costs and enabling a secure environment.

The next-generation IBM TS4500 tape library is designed to help midsized and large enterprises meet cloud storage challenges, including data volume growth, rising storage footprint costs, data migration efforts and the increased complexity of IT training and management as staff resources shrink.

TS4500 answers those business needs by incorporating the latest generation of industry-leading LTO technology that will help organizations handle the growing data demands of modern tape use cases like big data, cloud, media and entertainment, ultra high-definition editing, digital video surveillance, Internet of Things (IoT), active file archiving and, of course, backup.

TS4500 delivers the density that today’s data growth requires—along with the efficiency and manageability to grow with business needs while preserving your existing investments in IBM tape library products. You can achieve both a low per-terabyte cost and high density, with up to 8.76 PB of data in a single 10 square-foot library using LTO Ultrium 8 cartridges or 12.37 PB with 3592 cartridges.

TS4500 provides advanced capabilities for integrated tape drive and media management, delivered within a single-pane-of-glass management console. The TS4500 graphical user interface (GUI) is based on the unified interface used in other IBM storage solutions. It includes key features to help guide storage administrators in completing critical tasks. For example, you can monitor a tape library via persistent, at-a-glance library utilization and health status indicators.

IBM TS4500 features such as automatic control-path and data-path failover, tape-drive encryption, dual robotic accessors and WORM media support improved management and help to reduce risk in the cloud.

In addition, IBM TS4500 now supports IBM z14, the latest generation of IBM Z servers. Mainframe administrators can trust TS4500 to help reduce floorspace costs and increase overall capacity.

Automates solutions for cloud environments

TS4500 is a tape drive integration leader, with features including a persistent worldwide name, multipath architecture, drive/media exception reporting, remote drive/media management and host-based path failover. TS4500 L25, D25 and S25 frames support the IBM TS1160, TS1155, IBM TS1150, and IBM TS1140 tape drives, while TS4500 L55, D55 and S55 frames support LTO Ultrium 8, 7, 6 and 5 tape drives. LTO Ultrium tape drives and TS1160, TS1155, TS1150 and TS1140 tape drives can be mixed within the TS4500 library, frame by frame. The L-frame and D-frame models help boost efficiency with improved hot-swappable drive packaging. All of the frames include high-density (HD) slot technology that can greatly increase a library’s total capacity.

TS4500 frame models can be placed in any active position, so the library can grow from both the right and the left side of the first L frame for floorspace flexibility. A dual-accessor option can help increase mount performance and overall system reliability and availability. Accessors can be serviced at the ends of the library, eliminating the need for a dedicated service bay frame.

A top-rack offering can also provide 10U of rack space on top of the library for Fibre Channel switches, tape data movers or IBM Spectrum Archive nodes.

Delivers capacity on demand

The TS4500 library frame provides a more flexible upgrade path for users who want to expand their tape storage as their needs grow. Capacity-on-demand configurations for TS4500 L-frame models include an entry-level configuration, an intermediate configuration and a base-capacity configuration. All models also support HD capacity-on-demand configurations.

Includes advanced features

TS4500 is designed with advanced features to deliver cutting-edge performance and long-term value. For example, the Advanced Library Management System (ALMS) feature supports dynamic storage management, enabling you to create and change logical libraries and configure any drive into any logical library. TS4500 also offers automatic control-path and data-path failover to help improve business continuity and disaster recovery, and policy-based automatic media verification can help minimize data risk.

Centralizes management of tape resources

IBM offers a wide range of management software options for TS4500. The management software options include:
  • IBM Spectrum Archive—Allows users and applications to directly access files and directories stored on tape
  • IBM TS4500 command-line interface (CLI)—Provides access to TS4500 library management commands
  • Rocket Servergraph Professional—Enables administrators to monitor and report on storage devices
  • IBM Tape System Library Manager—Allows multi-library environments to be managed as a single system
  • IBM Security Key Lifecycle Manager—Simplifies encryption key management with an intuitive user interface
