Understanding the DR Series System
The 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 the assurance of no hidden costs for desired future features.
NOTE: Unless otherwise noted, later references to "the system" or "DR Series system" are used interchangeably to
represent the Dell DR Series system.
The DR Series system has a simple installation process with full, intuitive remote setup and management capabilities. It
is available in many 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
Drive and Available Physical Capacities .
NOTE: The DR Series system also supports using 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 “Expansion Unit
Limits” in the
Dell DR Series System Interoperability Guide
and Installing an Expansion Shelf License , DR Series
System - Expansion Shelf Cabling , and Expansion Shelf Licenses in this guide.
Using Dell deduplication and compression algorithm technology, this 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
removing redundant data, the system provides deduplication and compression that 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
function—to provide a complete backup solution for multi-site environments.
The shorter Recovery Time Objectives (RTO) and more attainable Recovery Point Objectives (RPO) can also be 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:
• Advanced data protection and disaster recovery
• Simple management interface (using the system GUI)
• Wide variety of data backup installations and environments
The Dell DR Series system contains data backup and management software preinstalled on a Dell hardware appliance,
which provides you with a robust disk-based data backup capability installed on a deduplication-enabled appliance.
The system supports two interface types, and the system software manages the storage containers using the following
interfaces:
• A command line interface (CLI)
• A graphical user interface (GUI)
