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.
メモ: 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 the following drive capacities—2.7 Terabytes (TB), 5.4 TB, 9 TB, 18 TB, and 27 TB (the 27 TB drive capacity
was added in Release 2.0), and is ideal for both small enterprise and remote office environments. The DR Series system
and corresponding drive capacities are as follows:
• 300 Gigabyte (GB) drive capacity: 2.7 TB system (this system version does not support the addition of expansion
shelf enclosures)
• 600 GB drive capacity: 5.4 TB system
• 1 TB drive capacity: 9 TB system
• 2 TB drive capacity: 18 TB system
• 3 TB drive capacity: 27 TB system
メモ: To better understand the drive capacity and the available physical capacity for the drive types available in
the DR Series system, see Drive and Available Physical Capacities.
メモ: Release 2.0 also supports using an external data storage expansion shelf (also known as expansion
enclosures). The DR Series system supports up to two expansion enclosures per system. 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
Installing an Expansion Shelf License, DR Series System - Expansion
Shelf Cabling, and Expansion Shelf Licenses.
Using Dell deduplication and compression algorithm technology, this system can achieve data reduction levels ranging
from 10:1 to 50:1. 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)
