What is QXS Hybrid Storage?

QXS hybrid storage is a family of primary storage systems that make it easy to select the perfect system for your environment and budget. QXS hybrid systems are customizable and scalable by alternating key elements. While all QXS hybrid systems are available with intelligent tiering, the QXS-3 Series features a balanced mix of reliability and availability; the QXS-4 Series delivers the optimal mix of performance, cost and storage density while the QXS-6 meets the IOPS requirements of the most demanding workflows.

Why QXS is the Best Solution:

Intelligent Data Tiering

Tiering data based on usage is a necessity. Keeping in-demand data in the highest-performing storage is the smart thing to do. QXS hybrid storage incorporates intelligent data access algorithms to ensure the most requested data is in the highest-performing tier seamlessly and automatically. This enables the optimal use of higher-cost, high-performance storage.

Intelligent data tiering
Designed for speed

Designed for Speed

All-flash performance for a fraction of the cost. We built QXS hybrid storage to be fast—really fast. QXS hybrid systems maximize performance regardless of disk type or configuration—all disk, all flash or flash and disk. With as little as 10% capacity dedicated to flash, QXS hybrid performance is up to 200,000 IOPS and is on par with all-flash arrays at a fraction of the cost. Designed for demanding sequential I/O performance, we use multi-core processing, active-active controllers, and separate paths for internal management and external data access.

Systems Pre-configured for Optimization

Confidence when installing new storage systems. QXS hybrid storage is offered with 1-button configurations. These 1-button configurations are optimized for specific workflows and applications that have been extensively tested by Quantum. There is no risk or uncertainty when you install pre-defined, thoroughly tested QXS hybrid storage systems.

Built for reliability

Built for Reliability

Achieve 99.999% availability. By design. With QXS industry-leading reliability, you can be assured that your mission-critical applications will always be available. With the dual, redundant design, QXS systems eliminate single points of failure. Designed to meet military and telecommunications specifications, the systems will perform, without failure, in extreme conditions.

Exceed Requirements; Stay Within Budget

Managing unrelenting storage growth requires a strong partner. QXS true hybrid storage systems’ automatic, intelligent tiering optimizes flash and disk to keep performance up and costs down. For most applications, up to 95% of IOPS can come from as little as 10% flash. Flexibility and scalability are required to manage an efficient storage environment. QXS systems are available in a variety of configurations, including up to 3 tiers of storage within an array, and seamlessly support additional SSDs, HDDs, and expansion chassis when needed.

Exceed requirements; stay within budget


Optimize your storage investment by ensuring frequently accessed data is in the highest performing storage.

QXS hybrid storage is customizable using a variety of controllers, chassis, devices and software tools to create the optimal solution for your business.
