2 Understanding the DR Series System 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 allinclusive licensing model ensure optimal functionality and provide the assurance of no hidden costs for valuable future features. NOTE: Unless otherwise noted, later references in this guide to "the system" or "DR Series system" are used interchangeably to represent the Dell DR Series system. 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. 12
