Feature spotlights

Uncompressed data storage in a single frame

Store up to 8.76 PB of data in a single 10 square-foot library using LTO 8 cartridges or 8.25 PB with 3592 cartridges.

Policy-based automatic media verification

Proactively monitor archived data 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 Linear Tape-Open (LTO) Ultrium 8, 7, 6, and 5, and IBM TS1155, TS1150, and TS1140 tape drives.

IBM Spectrum Archive support

Simplify user access to data stored on tape cartridges via IBM Spectrum Archive™ featuring IBM Linear Tape File System™ technology.

Compatibility with new IBM LTO Ultrium 8 technology

Supports the latest generation of Linear Tape-Open (LTO) technology, offering up to 30 TB of data storage per cartridge (12 TB native), twice the compressed capacity of the previous LTO Ultrium 7 cartridges. Also, an initialization feature will allow you to use new LTO generation 7 cartridges as LTO-8 Type M media cartridges ready to be initialized on site to increase capacity from 6 TB to 9 TB. Initialization capability will be enabled on TS4500 by updating to the latest library firmware.

Optional 10U of rack space available above the library

Reduce the storage footprint and simplify cabling with 10U of rack space on top of the library.

Supports most open-system servers including IBM Z®

Helps to simplify the storage environment and enable flexibility for growth and change in your data center.
