Understanding the DR4000 System
The DR4000 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 "DR4000 system"
in this guide are used interchangeably to represent the Dell DR4000 system.
The system has a simple installation process with full, intuitive remote setup
and management capabilities and is available in the following usable
capacities—2.70 Terabytes (TB), 5.4 TB, or 9 TB (or up to 18 TB with two
drives in this release), and is ideal for both small enterprise and remote office
environments.
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 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 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.

Block-level deduplication works efficiently where there are multiple duplicate
versions of the same file. This is because it looks at the actual sequence of the
data–the 0s and 1s–that comprise the data.
Whenever a document is repeatedly backed up, the 0s and 1s stay the same
because the file is simply being duplicated. The similarities between two files
can be easily identified using block deduplication because the sequence of
their 0s and 1s remain exactly the same. In contrast to this, there are
differences in online data.
Online data has few exact duplicates. Instead, online data files include files
that may contain a lot of similarities between each file. For example, a
majority of files that contribute to increased data storage requirements come
pre-compressed by their native applications, such as:
• Images and video (such as the JPEG, MPEG, TIFF, GIF, PNG formats)
• Compound documents (such as .zip files, email, HTML, web pages, and
PDFs)
• Microsoft Office application documents (including Powerpoint, MS-Word,
Excel, and Sharepoint)
NOTE: The DR4000 system experiences a reduced savings rate when the data it
ingests is already compression-enabled by the native data source. It is highly
recommended that you disable data compression used by the data source, and
especially for first-time backups. For optimal savings, the native data sources need
to send data to the DR4000 system in a raw state for ingestion.
Block deduplication is not as effective on existing compressed files due to the
nature of file compression because its 0s and 1s change from the original
format.
Data deduplication is a specialized form of data compression that eliminates
a lot of redundant data. The compression technique improves storage
utilization, and it can be used in network data transfers to reduce the number
of bytes that must be sent across a link. Using deduplication, unique chunks
of data, or byte patterns, can be identified and stored during analysis.
As the analysis continues, other chunks are compared to the stored copy and
when a match occurs, the redundant chunk is replaced with a small reference
that points to its stored chunk. This reduces the amount of data that must be
stored or transferred.

By contrast, standard file compression tools identify short repeated substrings
inside individual files, with the intent of storage-based data deduplication
being to inspect large volumes of data and identify large amounts of data such
as entire files or large sections of files that are identical.
Once this has been done, this process allows for the system to store only one
copy of the specific data. This copy may be additionally compressed using
single-file compression techniques.
For example, there may be cases where an email system may contain 100 or
more emails where the same 1 megabyte (MB) file is sent as an attachment
and the following shows how this is handled:
• Without data deduplication, each time that email system is backed up, all
100 instances of the same attachment are saved, which requires 100 MB of
storage space.
• With data deduplication, only one instance of the attachment is actually
stored (all subsequent instances are referenced back to the one saved
copy), with the deduplication ratio being approximately 100 to 1).
NOTE: The DR4000 system does not support deduplication of any encrypted data,
so, there will be no deduplication savings derived from ingesting encrypted data.
The DR4000 system cannot deduplicate data that has already been encrypted
because it considers that data to be unique, and as a result, cannot deduplicate it.
For the case where you self encrypting drives (SEDs) were used, when data is
read by the backup application it is decrypted by the SED or the encryption
layer (for example, as if you were opening an MS-Word document that was
saved on a SED). If you enable encryption in the backup software, you will
lose deduplication savings because each time the data is encrypted, the
DR4000 system considers it to be unique.
Replication
Replication is the process by which the same saved data is saved from
multiple storage devices, with the goal of maintaining consistency between
redundant resources in data storage environments.
Data replication improves fault-tolerance, which improves the reliability of
maintaining saved data, and permitting accessibility to the same stored data.
The DR4000 system uses an active form of replication that lets you configure
a primary-backup scheme in which the system processes data storage requests
from a specified source to a specified destination or replica.

NOTE: It is important to distinguish the difference between data that has been
processed by backup and data that has been processed by replication, since
backup saves a copy of data that remains unchanged for a long period of time.
Replicas on the other hand are frequently updated and can quickly lose any
historical state. The DR4000 system can be considered as a form of a storage
replication process in which the backup and deduplication data is replicated
in real-time or via a scheduled window in a network environment. Replication
in the DR4000 system involves the use of a replication relationship between a
pair of DR4000 systems, a source and a target system.
However, if the source and target systems in a replication pair are in different
Active Directory (AD) domains, then data that resides on the target system
may not be accessible. When AD is used to perform authentication for
DR4000 systems the AD information is saved with the file, which restricts
user access to the data based on type of AD permissions in place.
NOTE: This same authentication information is replicated to the target DR4000
system when you have replication configured. To prevent domain access issues,
ensure that both the target and source systems reside in the same Active Directory
domain.
Reverse Replication
The concept of reverse replication is not supported on DR4000 systems. This
is because replica containers are always in a R-O (read-only) mode on the
DR4000 system, this not making write operations a supported operation.
Under very specific conditions, it might be possible for replica containers to
support a type of write operation whose sole function is to restore data from
an archival target. For example, data could be replicated back to the remote
site where a data management agent (DMA) is connected to allow this data
to be restored directly.
This specific case applies only to configurations where data is backed up from
a remote location to a local container, and then replicated over a WAN to a
replica container that is backed up to tape. The data needs to be restored
from the tape backup to the original location; first back to a DR4000 system
replica container, and then back to the original source location of the data on
the other side of the WAN link.
NOTE: If you choose to use this alternate workaround method, you must set up a
new data storage unit in the DMA and import the images before a restore to the
original location can occur.

To support this effort to leverage deduplication across the WAN to allow this
scenario, complete the following:
1
Make sure that the replication operation has completed (between source
and target).
2 Delete current replication relationship, and re-create replication
relationship (reversing the source and target roles).
3 Restore data to the original target container (now the source).
4 Make sure that the replication operation has completed.
5 Delete replication relationship and re-create replication relationship
(restoring original source and target destinations).
Under this scenario, a fraction of the data to be recovered is sent across the
WAN link. This could speed up a remote restore significantly. However, there
are some downsides to this type of scenario:
• If step 1 is not followed correctly, any changes not fully replicated are lost.
• During steps 2 and 3, any data that is written to the original DR4000
system source container may be lost.
• During step 4, if the data is not fully replicated back before the switch is
made, it may be lost.
Alternatively, you still could support this effort by completing the following:
1
Create a new container on the target DR4000 system.
2 Set up replication from this container back to the source DR4000 system
container.
3 Set up a new disk storage unit in the DMA and make sure that the DMA is
aware of any new images.
4 Import the old images back into the DMA from the target DR4000 system
(the original source location).
5 Use a new disk storage unit in the DMA, and then restore the data back to
the original client.
Supported File System Protocols
The DR4000 system supports two types of file system protocols:
•NetworkFileSystem(NFS)
• Common Internet File System (CIFS)

NFS
NFS is a network file system protocol that is designated to be a file server
standard, and its protocol uses the Remote Procedure Call (RPC) method of
communication between computers.
Clients can access files via the network similar to the way that local storage is
accessed. NFS is a client-server application in which a client can view, store,
and update files on a remote system just like they are working on the local
system. Administrators can mount all or a portion of a file system, and the file
system (or portion) that is mounted can be accessed using the privileges
assigned to each file. The NFS protocol supports UNIX, Macintosh,
OpenVMS, and the Microsoft Windows operating systems.
CIFS
CIFS is an alternative remote file access protocol and is also known as Server
Message Block (SMB). SMB occurs more commonly than NFS on systems
that run the Microsoft Windows operating system. CIFS allows programs to
request files or services on remote computers.
CIFS also uses the client-server programming model, whereby the client
requests access to a file or passes a message to a program running on the
server. Servers review all requested actions and return a response. CIFS is a
public (or open) variation of the SMB that was originally developed and used
by Microsoft.
NOTE: For details on CIFS feature restrictions, see the Dell DR4000 System
Interoperability Guide , at support.dell.com/manuals.

DR4000 System and Data Operations
Data is stored and resides on the Dell DR4000 system, which is a 2-Rack Unit
(RU) appliance, and the system software is pre-installed. The internal drives
of the system are configured as a Redundant Array of Independent Disks
(RAID) 1 on the RAID Controller, which is considered to be volume 1. The
data being backed up is stored on virtual disks that reside on the appliance.
The hot-swappable data drives that are attached to the RAID controller are
configured as:
• 11 drives operating as RAID 6, which act as virtual-disks for data storage.
• The remaining drive (drive 12) acts as the global hot-spare drive for the
system.
The DR4000 system supports RAID 6, which allows the appliance to continue
read and write requests to the RAID array virtual disks even in the event of
concurrent disk failures, providing protection to your mission-critical data.
The system design supports double-data drive failure survivability if either of
the following service operations are performed:
• System board replaced
• Boot disks are reinitialized or system software is reinstalled
If the system detects an unconfigured drive, then the data is automatically
copied from the global hot spare (GHS, drive slot 0). The global hot spare
again behaves as a spare. This scenario is usually encountered when a faulty
data drive is replaced.

Setting Up the DR4000 System
Interacting with the DR4000 System
You interact with the system using the web-based DR4000 system GUI using
a browser-based connection. The system provides a single, comprehensive
data management interface that lets you create new data containers, modify
or delete already existing containers, and perform a number of data-related
operations using its features and settings.
Any container you can manage is a defined space where you can store your
backup and deduplication data. A data container is a shared file system that is
imported using a client, and is accessible via NFS or CIFS filesystem
protocols.
The system provides real-time summary tables, detail tables, and graphs that
let you monitor the status of the data capacity, storage savings, and the
throughput of the containers you are managing using its features.
Networking Preparations for the DR4000 System
Before you can start using the system, ensure that:
• An active network is available using Ethernet cables and connections.
NOTE: If your DR4000 system is equipped with a 10-GbE NIC, you must use
CAT6 copper cabling.
NOTE: If your DR4000 system is equipped with a 10-GbE enhanced small form-
factor pluggable (SFP+) NIC, you must use Dell-supported SFP+ LC fiber-optic
transceivers or twin-axial cabling.
• IP addresses are assigned to the DR4000 system. The system ships with a
default IP address and subnet mask address, which should only be used
for an initial system configuration.
To perform an initial configuration, you need:
NOTE: Have an IP address available to replace the default IP address if you
choose the static mode of IP addressing, or select to use the DHCP mode of IP
addressing.

– An IP address for the system
– A subnet mask address
– A default gateway address
–ADNSsuffixaddress
– A primary DNS server IP address
– (Optional) A secondary DNS server IP address
• NIC connection bonding: by default, the DR4000 system will configure
its NIC interfaces together as a bonded team
(and only one IP address is
needed because the bonded NICs assume the primary interface address).
NIC connection bonding can use either of these configurations:
– Adaptive load balancing (ALB), which is the default setting, does not
require any special network switch support. Ensure that the data
source system must be on the same subnet as the DR4000 system. For
more information, see "Configuring Networking Settings" on page 31.
– 802.3ad or dynamic link aggregation (using the IEEE 802.3ad
standard). 802.3ad requires special switch configuration before using
the system (contact your network administrator for 802.3ad
configuration).
NOTE: To configure a 10-GbE NIC or 10-GbE SFP+ bonded configuration,
connect only the 10-GbE/10-GbE SFP+ NICs (1-GbE NICs are disabled when
the 10-GbE/10-GbE SFP+ NICs are present).
• DNS: you need a DNS domain available, and you need to know the
primary DNS server IP address (and a secondary DNS server IP address,
if you choose to configure one).
• Replication ports: the replication service in the system requires enabled
fixed ports be configured to support replication operations being
performed across firewalls (TCP ports 9904, 9911, 9915, and 9916). For
more information about system ports, see "Supported Ports: DR4000
System" on page 129.
