The Dell DR4000 system contains data backup and management software
pre-installed 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)
About the DR4000 System
The Dell DR4000 system is a solution designed to reduce your backup data
footprint using file-aware and content-aware backup and deduplication
operations that optimize storage savings. The system consists of:
•
Software
—the
system software supports record linkage and context-based
lossless data compression methods.
•
Hardware
—the
system appliance includes twelve 3.5-inch SAS or Nearline
SAS chassis drives that are hot-swappable, two power supplies for power
redundancy, and two cabled 2.5-inch SAS drives for the operating system.
NOTE:
The operating system is installed on two internal drives in a RAID 1
configuration.
Data Storage Terminology and Concepts
Data Deduplication and Compression
The DR4000 system design draws upon a wide variety of data-reduction
technologies that include the use of advanced deduplication algorithms, in
addition to the use of generic and custom compression solutions that are
effective across a large number of differing file types.
The system uses a concept of content-awareness where it analyzes data to
better learn and understand the structure of your files and data types. Once
this is learned, it uses this method to improve your data reduction ratios while
reducing resource consumption on the host.
The system uses block deduplication to address the increasing data growth,
and this is well suited to providing the best results for routine and repeated
data backups of structured data.
