The Limitations of Conventional Enterprise Disk Backup

Using disk deduplication appliances for Enterprise-scale backup presents major problems for many IT departments. Large-scale disk backup systems often can’t deliver the kind of backup performance, data reduction rates, and replication capability needed to protect Enterprise assets or to centralize data from branch and remote offices. And interfaces with backup software are frequently limited, making it hard to switch applications or to move data to a tertiary layer, like tape, for DR protection.

Conventional appliances also become more and more expensive as they mature. They often balloon in size, forcing IT departments to dedicate more and more space, power and cooling to them. And upgrade costs, including surprise maintenance fee hikes, often make expanding systems unaffordable. 

Enterprise Backup and Replication

DXi9000 is a true enterprise-scale disk backup system. It provides industry leading performance of up to 99 TB per hour with Accent and up to 20.4 PB logical capacity. DXi9000 is completely compatible with all leading backup software, and up to 128 partitions can present themselves as CIFS/NFS shares, VTLs, or OST LSUs for maximum flexibility. Replication, encryption, full hardware redundancy, and an integrated path to tape are standard features, keeping costs low and predictable.

DXi9000 solves two costly data center issues: resource use and growth. It offers the smallest data center footprint of any leading disk backup system, along with lowest power and cooling needs. And it provides the industry’s least disruptive scalability—even providing a capacity-on-demand option that allows users to add capacity by simply turning on a software key. 

Two smiling co-workers in data center



The DXi9000 is designed for the core of Enterprise data centers, with scalability from 51 TB to 1 PB. The DXi9000 uses the latest SSD technology to speed every aspect of system performance and uses 12 TB HDDs and a new high-density chassis design to provide the best density in the market.

Maximize Data Reduction

All DXi appliances leverage Quantum's variable-length data 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.

Support for OST is a standard feature for all DXi9000 backup appliances, allowing users to write data to OST logical storage units (LSUs) and enabling application-aware replication in NetBackup and Backup Exec environments. Support includes Optimized Duplication, Auto Image Replication (AIR), and Granular Restore Technology (GRT). OST path-to-tape introduced in NetBackup 6.5.4. OST Optimized Synthetic Full Backups is also supported to reduce network I/O and shorten time to perform full restore from incremental backups.

The DXi Dynamic Application Environment (DAE) enables the installation of a KVM hypervisor to support virtual machines running many different operating systems on DXi appliances. DXi supports Veritas NetBackup and Nakivo Backup & Replication running in DAE for customers who wish to save money and data center space by eliminating the need to deploy a separate server to run their backup application. Customers may run NAS and OST backups directly from their DXi appliance running NetBackup within the DAE.

The integration of DXi and Veeam enables the Veeam Data Mover Service (VDMS) to be used to move data between the Veeam proxy server and the DXi appliance. The VDMS communicates with the Veeam proxy server to efficiently manage the data flow between Veeam and DXi, greatly reducing the time it takes to create synthetic full backups with Fast Clone by up to 15x and run VM instant recovery. DXi appliances are a Veeam Ready Integrated storage solution. This program offers Veeam Alliance Partner Program members the opportunity to create solution offerings that complement or enhance Veeam features or functions. Through more extensive product integration, joint development and testing, these enhanced solutions help customers achieve optimal performance or create unique abilities together with Veeam Backup & Replication™ APIs or technologies. The DXi when defined as a repository for Veeam supports the use of the Veeam Data Mover Service (VDMS), which optimizes performance between the DXi and the Veeam proxy server.

DXi Accent software, a standard feature on all DXi9000 backup appliances, allows the backup server to collaborate in the deduplication process, off-loading part of the data reduction activity so that only unique blocks are sent over the network to the DXi appliance. This distributed approach provides faster backups over bandwidth-constrained LANs or WANs. DXi Accent can be enabled or disabled on a per-media server basis. Initial support for DXi Accent is provided through the NetBackup Backup Exec OpenStorage (OST) API, AccentFS for Oracle RMAN, and Linux OS over LAN/WAN.

Data-at-rest encryption uses self-encrypting drive (SED) technology to secure all data stored on the DXi9000 and helps render breached data useless to anyone not authorized to access it. This includes file data and metadata, configuration files, and the DXi software and operating system. When data-at-rest encryption is enabled, all hard drives in the DXi are paired with the disk controllers using encryption keys. Then, accessing data on the drives requires the same encryption keys and controllers that were used to write the data. This ensures that a drive that is physically removed from the DXi cannot be read using another system or device.

DXi Advanced Reporting, which is included on all DXi appliances, sets new standards for onboard intelligence by giving users a detailed view of internal appliance operations, providing them with years of backup and replication data for extended trend analysis. DXi Advanced Reporting reduces administration time, improves operations, streamlines performance tuning, and helps users maximize the value of their DXi appliances.

Replication is supported for any DXi to any Quantum DXi appliance and is encrypted (AES 256-bit) and asynchronous. Customers can choose a desired replication strategy: one to one, one to two, or fifty to one. Every partition in a DXi unit can be a source and target, similar to peer-to-peer replication. Replication starts as backup ingest occur to reduce replication time.
