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 6 PB 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.

Quantum’s iLayer management software, at the core of every Scalar library, has been fully refreshed, bringing system setup and management to a whole new level of ease. An intuitive, mobile-first designed management interface guides users quickly through the setup process. And its proactive diagnostic feature ensures the system stays up and running with minimal administrative involvement—saving valuable time and operating expenses.

While Scalar i3 is designed as an easy-to-manage, cost-effective, entry-level tape library, it has the flexibility to grow as storage needs change. Scalar i3 can scale cartridge slots from 25 up to 200, in 25-slot increments with Capacity-on-Demand (CoD) software licensing, increasing compressed LTO-8 capacity from 750 TB up to 6 PB. Scalar i3 also supports from 1 to 12 tape drives, allowing users to balance read/write performance as needed.

Scalar i3 comes packed with high-efficiency features designed to minimize the total storage costs. Features like best-in-class storage density (reducing data center footprint with up to 6 PB in just 12U), and 80 PLUS certified power supplies (requiring the lowest power and cooling needs), minimize the operating costs of storing data off-line for ransomware protection or the long-term preservation of archive data.
