The Dell DR Series system is a high-performance, disk-based
backup and recovery appliance that is simple to deploy and manage
and offers unsurpassed Total Cost of Ownership benefits. Features
such as innovative firmware and an all-inclusive licensing model ensure
optimal functionality and provide the assurance of no hidden costs
for valuable future features.

A purpose-built disk platform, the DR Series system
provides advanced deduplication and compression technology to store
data most efficiently. The DR Series hardware appliances are 2U, rack-based,
system backup storage repositories, that include deduplication and
compression technology in their operating systems. A virtual machine
(VM) version is also available (that is combined with a DR Series
hardware appliance) to provide robust, disk-based data backup capability
on VMs, while taking advantage of a deduplication-enabled appliance.
Using Dell deduplication and compression algorithm
technology, a DR Series system can achieve data reduction levels ranging
from 10:1 to 15:1. This reduction in data results in less incremental
storage needs and a smaller backup footprint. By taking advantage
of deduplication and compression features and removing redundant data,
the system:
- Delivers fast, reliable backup and restore functionality
- Reduces media usage and power and cooling requirements
- Improves overall data protection and retention costs
The benefits of data deduplication can be extended
across the enterprise—through the deduplicated replication functionality—to
provide a complete backup solution for multi-site environments. The
shorter Recovery Time Objectives (RTO) and attainable Recovery Point
Objectives (RPO) are also assured as critical backup data remains
on disk and online longer. Capital and administrative costs are diminished
at the same time as internal service level agreements (SLAs) are more
easily met.
The DR Series system includes the following features:
- Advanced data protection and disaster recovery
- Two management interfaces, a command line interface
(CLI) or a system graphical user interface (GUI) for the system software
to manage storage containers
- Wide variety of data backup installations and environments
- A simple installation process that provides full,
intuitive remote setup and management capabilities
The DR Series system is available in a variety of drive
capacities and is ideal for SMB, enterprise, and remote office environments.
For details about specific drive capacities and types available in
the DR Series system, see the
DR Series System Interoperability
Guide
or the latest
DR Series System Release Notes.

NOTE: DR Series system hardware
also supports the use of external data storage expansion shelves (also
known as expansion enclosures). An added expansion shelf enclosure
must be equal to or greater than each DR Series system internal drive
slot capacity (0–11). For more information about expansion enclosures,
see the topic, “Expansion Unit Limits,” in the
Dell DR Series System
Interoperability Guide
and the related Expansion Shelf topics
in this guide.
