The Scalar® i6 tape library delivers the highest storage density in LTO automation, scaling up to 12PB in a standard 19-inch rack, providing the lowest cost per GB within a single rack. Integrated iLayer™ features like policy-based data integrity checking, automated in-library vaulting, and in-depth system monitoring and reporting ensure valuable content is available when needed, making Scalar i6 the best choice for demanding workflows. And it’s a Scalar, the market share leader in LTO automation, so you know it’s reliable.

What is Scalar i6?

Scalar i6 is an intelligent tape library designed for enterprise data centers and the world’s most demanding workflows. The embedded iLayer software is proven to reduce management time and improve system uptime. And with its fully refreshed, modern intuitive user interface, administrative tasks are further automated and simplified, saving valuable user time. With scaling capacity up to 12PB within a single 19-inch rack (4.8PB uncompressed), Scalar i6 is ideally suited for retaining valuable rich media content, video surveillance footage, and unstructured data archives. And its highly efficient features, like the best storage density and 80 PLUS®-certified power supplies, reduce your data center footprint—minimizing long-term storage, power, and cooling costs.

Massive growth of unstructured data is challenging IT organizations across all industries. The sheer scale of data under management and its rapid growth rate is requiring new levels of storage efficiency. Organizations are realizing the best approach is an intelligent, multi-tiered storage solution that balances performance and cost, and scales easily while providing users with simple access to all their stored content. As the lowest-cost storage technology, tape is playing an important role in these new solutions. Scalar® i6 provides the most efficient, lowest-cost storage solution for these demanding workflow environments.

High Efficiency

Scalar i6 delivers best-in-class storage density with up to 12PB in a single 19-inch rack, minimizing valuable data center footprint. 80 PLUS®-certified power supplies require the lowest power and cooling, further minimizing ongoing operating costs, while iLayer™ software features like Proactive Diagnostics and RESTful web services save valuable library administration time.

Data Integrity And Security

Policy-based data integrity checks are automated with the Extended Data Life Management (EDLM) feature, ensuring stored content remains readable. With intelligent data management applications like Quantum’s StorNext®, suspect tapes can have content migrated automatically to a new tape, creating a self-healing archive. And in-library vaulting provides protected long-term storage in the security of the customer’s data center. Additional security features like AES 256-bit encryption and media removal notifications ensure valuable content is protected from unauthorized access.


A modular design simplifies scalability for managing growth. Each Scalar i6 module supports up to three full-height LTO tape drives and 100 storage slots, for up to 1.5PB of storage per module. Capacityon-Demand (CoD) slot licensing in 25-slot increments provides small granularity to better manage your storage costs in a pay-as-you-grow approach, with capacity scaling from 750TB up to 12PB within a single 19-inch rack.
