Mid-sized Environments Face Unique Backup Challenges

Mid-sized Environments Face Unique Backup Challenges

Medium-sized businesses and remote office locations often struggle to keep backup working effectively while keeping costs low.  Many disk backup products can leave data vulnerable to malware, and they can make it difficult to get copies of files off-site for true DR protection.  

Tape traditionally has been an answer, but unpredictable data growth makes it hard to plan backup systems, and most tape libraries make scaling complex and expensive.  On top of that, traditional tape libraries can cost IT admin staff hours and hours in management time. 

Modular Tape System Solves the Problems

Scalar i3 was designed specifically to give mid-sized IT environments the kind of protection provided by LTO media, while solving the problems associated with cost, scaling, and management. The Scalar i3 can start as a single, 3U unit, providing dense, cost-effective backup storage of up to 750 TB.  But then it can scale in 25-cartridge increments as data volumes increase—all the way up to 12 PB.  Its Capacity-on-Demand (CoD), software-key growth makes growing the system easy and economical.

The Scalar i3 features simple cartridge-based media handling, and it uses Quantum’s intelligent iLayer™ management software to monitor library systems and provide intuitive, proactive alerts. The result is the industry’s best tape backup protection at the lowest total ownership cost.

Modular Tape System Solves the Problems

Featured Benefits


Reduce Administration Time

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 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.


Manage Data Growth

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 400, in 25-slot increments with Capacity-on-Demand (CoD) software licensing, increasing compressed LTO-8 capacity from 750 TB up to 12 PB. Scalar i3 also supports from 1 to 24 tape drives, allowing users to balance read/write performance as needed.


Maximize Efficiency, Minimize Costs

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 12 PB in just 24U), and 80 PLUS® certified power supplies (requiring the lowest power and cooling needs), minimize the operating costs of storing data offline for ransomware protection or the long-term preservation of archive data.
