Efficient. Intelligent.
Enterprise Scale.

The Scalar® i6 tape library delivers the highest storage density in LTO automation, scaling up to 24 PB 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 24 PB within a single 19-inch rack (9.6 PB 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.

Featured Benefits


Maximize Efficiency

Scalar i6 is the most efficient tape library on the market when it comes to time, space, power and cooling needs. The refreshed iLayer management software automates tasks such as report generation and distribution, and can be easily customized using RESTful web services, minimizing library management time. With the highest rack density in the market—providing up to 24 PB in a single 19-inch rack (9.6 PB uncompressed)—Scalar i6 reduces your data center footprint while the 80 PLUS certified power supplies minimize power and cooling needs, saving on ongoing operating expenses.


Minimize Downtime

Scalar i6 has a comprehensive set of high-availability features to ensure the system remains operational and accessible. Redundant power supplies and path failover (for both robotic control and data path) provide the fault tolerance needed in an enterprise system. Additionally, intelligence built into the iLayer software provides a higher level of availability as advanced features like environmental and power monitoring, proactive diagnostics, and media-drive cross-tab reporting, identify trends and notify users of potential issues before faults occur—enabling proactive control of the library system to ensure maximum uptime.


Ensure Data Integrity and Security

Intelligent features available in Scalar i6 ensure that data stored for long-term retention remains both secure and preserved in a readable state. Extended Data Life Management (EDLM) runs policy-based integrity checks to ensure the data stored on tape remains readable. When coupled with intelligent data management applications, like Quantum StorNext®, content on suspect tapes can migrate automatically to a new tape, retaining data integrity levels set by the user-defined policies. Active Vault provides protected, automated, in-library vaulting for long-term storage in the security of a customer’s data center at a fraction of the cost of other vaulting solutions. And the EDLM feature can operate in the Active Vault partition, ensuring vaulted content remains available when needed. Additional security features like AES 256-bit encryption, with set-and-forget library-controlled key management, and media removal notifications, ensure valuable content is protected from unauthorized access.


Manage Data Growth

Scalar i6 has a modular design that simplifies adding storage slots for capacity growth and drives for greater performance. Each 6U module supports up to three full-height LTO tape drives and 100 storage slots, for up to 3 PB of storage per module. Capacity-on-Demand (CoD) slot licensing in 25-slot increments, provides a level of storage granularity to help you better manage your storage costs in a pay-as-you-grow approach, with capacity scaling from 1,500 TB up to 24 PB based on LTO-8 compressed capacity. Users can also save costs by using unlicensed slots with the optional Active Vault feature for secure in-library vaulting.
