Next-generation storage

The IBM® TS4500 Tape Library is designed to help midsized and large enterprises respond to cloud storage challenges. It incorporates the latest generation of industry-leading linear tape-open (LTO) and IBM enterprise class technology that will help organizations handle the growing data demands of modern tape use cases.

These challenges include high data volume growth in cloud and hybrid cloud infrastructures, increasing cost of storage footprints, the difficulty of migrating data across vendor platforms, and more.



Benefits Implement flexible growth

Grow from both the right and the left side of the first L frame, as models can be placed in any active position.

Support capacity on demand

Use support for entry-level, intermediate and base-capacity configurations.

Utilize dynamic storage management

Create and change logical libraries and configure any drive into any logical library.

Increase overall system availability

Help increase mount performance and overall system availability with dual robotic accessors.

Gain file-level access to data

Access data at the file-level without the need for proprietary applications.

Upgrade with a flexible path

Provide a flexible upgrade path when you want to expand your tape storage as your needs grow.


Features Scalability in a small footprint

Store up to 1.05 EB compressed data per 18-frame library and up to 39 PB compressed in 10 square foot library with 3592 cartridges.

Maximize storage capacity and density with LTO 9 technology

Store up to 1.04 EB compressed data per 18-frame library and up to 39 PB compressed data in a 10 square foot library.

Policy-based automatic media verification

Monitor archived data proactively with policy-based automatic media verification.

Data encryption and WORM media

Strengthen security and regulatory compliance with data encryption and write once read many (WORM) media.

Support for multiple tape drive combinations

Support any combination of LTO Ultrium 9 - 5, and IBM TS1160, TS1155, TS1150, and TS1140 tape drives.

IBM Spectrum® Archive support

Simplify access to data stored on tape cartridges through IBM Spectrum® Archive, featuring IBM Linear Tape File System (LTFS) technology.

Compatibility with IBM LTO Ultrium technology

Support up to 45 TB of compressed data storage per cartridge (18 TB native). Use new LTO generation 9 cartridges.

Optional 5U or 10U of rack space available above the library

Reduce your storage footprint and simplify cabling with extra rack space above the library for power distribution units, and more.

Supports for open-system servers 

Simplify your storage environment and enable flexibility for growth and change in your data center.


We currently have 1.2 PB of data on tape, and 2.5 PB on disk. Despite retaining more data, our cost per TB is excellent, and we are now meeting our storage needs in far more cost-effective way.”
