The Scalar® i3 tape library is designed for ease of use, from initial setup to ongoing management. Features like iLayer™ proactive diagnostics, Capacity-on-Demand (CoD) scalability, 80 PLUS-® certified power supplies, and best-in-class storage density ensure that Scalar i3 will save money on more than just the initial purchase. You’ll see why Scalar is the market share leader in LTO automation.

What is Scalar i3?

Scalar i3 is a tape library designed for small-to-medium size environments with a feature set focused on saving time and money. The Scalar iLayer management software—proven to reduce management time and improve system uptime—has been fully refreshed for even greater efficiencies and a modern, intuitive user experience. Scalar i3 can scale from 25 cartridge slots up to 200 slots, or 3PB on-demand, simplifying capacity planning and budgeting. And its highly efficient design—with features like the best storage density and 80 PLUS-certified power supplies—allows customers to reduce their tape footprint as part of their backup/DR strategy and for departmental archives.

Tape remains a popular storage choice for data backup and DR, longterm data retention, and unstructured data archives. Tape’s cost benefit, durability, portability, and off-line protection from ransomware are among the reasons for its sustained popularity. As IT organizations wrestle with rapid unstructured data growth and the increased risk of ransomware attacks, along with the business realities of resource constraints, it’s critical for IT solutions to maximize efficiencies beyond just acquisition costs.

Ease of Use

The Scalar® i3 tape library is designed for ease of use from initial setup to ongoing management. The Scalar iLayer™ management software, proven to reduce management time and improve system uptime, has been fully refreshed for even greater efficiencies and a modern, intuitive user experience. Its mobile-first user interface design allows library management from anywhere with a network connection on virtually any device.

High Efficiency

With features like best-in-class storage density, providing up to 0.75PB in just 3U and up to 3PB in 12U, along with 80 PLUS®-certified power supplies, Scalar i3 enables users to reduce their tape footprint and lower their power and cooling costs, ensuring savings on more than just the initial purchase.


Scalar i3 simplifies growth management with a modular design and Capacity-on-Demand (CoD) scalability. It can scale cartridge slots from 25 slots up to 200—instantly— with CoD software licensing, providing compressed capacities from 375TB up to 3PB. And users can add read/ write performance as needed, with support for up to 12 tape drives. With the partitioning feature, Scalar i3 can provide data protection and archiving in a single library as a valuable tool to address today’s IT challenges.
