IBM TS4500

A next-generation tape solution that delivers higher storage density and integrated management


The IBM TS4500 tape library is a next-generation storage solution designed to help midsized and large enterprises respond to storage challenges. Among these are high data volumes and the growth in data centers, increasing cost of data center storage footprints, the difficulty of migrating data across vendor platforms, and increased complexity of IT training and management as staff resources shrink.

In TS4500, IBM delivers the density that today’s and tomorrow’s data growth requires—along with the cost efficiency and the manageability to grow with business data needs while preserving existing investments in IBM tape library products. Now, organizations can achieve both a low cost per terabyte (TB) and a high TB density per square foot. In fact, TS4500 can store up to 2.2 PBs of data in a single 10 square foot library frame, up to 3.4 times more capacity than the IBM TS3500 tape library.
