Tape Storage

Scalar Tape Libraries

Low-cost, secure storage for long-term data archiving and cyber protection.

Scalar Security Framework Features

Low-Cost, Reliable Long-Term Data Storage for Massive Data Growth

Tape is the most cost-effective, secure storage option that requires very little power to store data for long periods and is a crucial component in the fight against cyber threats. Tape has also emerged as a key part of cloud and hyperscale infrastructures because it provides secure, long-term storage for compliance, digital media, and image archiving. As a result, the largest data centers on the planet are using tape extensively.

Quantum Scalar Tape Libraries Make Tape Easier to Manage

Quantum Scalar® Tape Libraries start as small as three rack units and 25 slots and can scale as large as over 20 racks in size. Every module offers Capacity-on-Demand (CoD) licensing, with configurable designs to accommodate data growth.

Quantum is the Leader in Hyperscale Cold Storage Archives

Scalar iLayer™ proactive diagnostics software is constantly monitoring the tape library environment, including media, tape drives, and the tape library itself. Degraded conditions, including media and drive conditions, can be detected and alerted proactively to make tape easier to manage and minimize downtime.

Key Components That Make Quantum Scalar Tape Libraries the Most Secure

Scalar Tape Libraries offer a cyber resilient solution that can be as small as a few tapes, scale within a rack, or can start at a full rack to grow according to your storage needs. Our automated security features enable you to efficiently store and manage your offline copies and keep them out of the reach of ransomware or other malware.

The Scalar Security Framework includes exclusive features with increasing levels of security, such as Active Vault, Logical Tape Blocking, and Ransom Block.

The Benefits of a Scalar Tape Library

Lowest-Cost Long-Term Storage

LTO tape continues to provide the lowest-cost long-term storage solution, and for PB-scale data sets is a fraction of the cost of public cloud and other cold storage solutions. Scalar Tape systems further reduce total cost with space efficient designs, iLayer® Proactive diagnostics and analytics, automated monitoring and reporting, and integration with cloud-based AIOps software to reduce administrative time.

Easily Manage Data Growth

A modular design that simplifies adding storage slots for capacity growth and drives for greater performance. Capacity-on-Demand (CoD) slot licensing 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 1,125 TB up to 540 PB based on LTO-9 compressed capacity.

Ensure Data Integrity and Security

Our Scalar Tape Libraries are the most secure tape libraries on the market, with over 25 unique features and capabilities that form a comprehensive security framework which controls system access, provides system monitoring and event detection, data security and encryption, and unique features for cyber protection and data integrity.

Minimize Downtime

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 and tape drive reporting identify trends and notify users of potential issues before faults occur—enabling proactive control of the library system to ensure maximum uptime.

Making the Grade with Video Archive

"When you look at not only cost per gigabyte, but harder to measure figures like the cost of cooling and power, the price advantage of tape is compelling. Add to that the scalability of Quantum libraries and the ability to better control what data goes on disk and what is archived or backed up on tape, and you’ll understand why we’re excited about all the things we can do with Quantum’s Scalar LTFS."
