DXi Backup Appliances

DXi® backup appliances provide high-performance, scalable storage for backup and multi-site disaster recovery, with the industry’s most efficient design. Variable-length deduplication maximizes data reduction, our unique replication engine enables multi-site protection and DR, and the high-efficiency design enables customers to maximize backup performance while minimizing data center footprint.

Backup Has Become a Critical, Enterprise-wide Challenge

Backup and DR protection have never been more important than they are today. Losing an organization's data can be catastrophic, and threats like ransomware increase every year. At the same time, data volumes are exploding, multi-site protection is mandatory, and while virtualization can save time and money, it can also make it harder to protect data. 
Unfortunately, many disk backup and software-based dedupe products can’t solve those problems. IT departments end up with disappointing data reduction, slow backups, replication that doesn’t work, incompatibility with backup apps, and expensive forklift upgrades that fill data centers with more and more spinning disk.

DXi Family Offers Solution for Organizations of All Sizes

Quantum’s DXi disk backup appliances provide a uniquely powerful solution. They start with the industry’s most effective variable-length deduplication—patented technology that minimizes disk requirements and dramatically shrinks the bandwidth needed for replication. Then they add the fastest disk backup and restore performance to keep backup windows short, and the smallest footprint so they use less data center space—along with power and cooling.  

DXi models fit from the smallest office to the largest Enterprise data center—some models even eliminate the need for new hardware by running as VMs—and they scale easily so that you can meet changing requirements at the lowest cost. Finally, DXi appliances integrate into the largest range of backup software in the industry, making it easy for you to protect data now and to change applications in the future.

Featured Benefits


Maximize Data Reduction

All DXi appliances leverage Quantum’s patented variable-length deduplication algorithm to maximize data reduction, minimize disk storage and minimize WAN traffic when replicating.


Maximize Production System Availability

DXi appliances provide high-performance ingest and restore capabilities for all leading backup applications.


Scale Capacity with Ease

DXi appliances make it easy to scale capacity more linearly as your data grows, often simply via a license key, and in more granular increments than other solutions.


Reduce Data Center Power and Cooling

DXi appliances deliver the most efficient design in the market, with best-in-class storage densities that enable customers to protect their data with fewer disks, which means less rack space, less power and less cooling.
