Chapter 1: System Description
Overview
Quantum DXi4700 User’s Guide 16
Overview
The DXi4700 is Quantum’s entry level and midrange disk backup solution that integrates data deduplication
and replication technology to connect backup and DR (disaster recovery) protection across distributed
corporate environments. The DXi4700 disk-based backup appliance uses Quantum’s patented data
deduplication technology to increase disk capacities by 10 to 50 times, and make WAN replication a
practical, cost-effective part of disaster recovery planning. With Capacity-on-Demand scalability from 5 TB
up to 135 TB, the DXi4700 is designed for departmental and medium business customers.
Advanced Data Deduplication Increasing Disk Retention
for Backup Data
The DXi4700 leverages Quantum’s patented data deduplication technology to dramatically increase the role
that disk can play in the protection of critical data. With theDXi4700 solution, users can retain 10 to 50 times
more backup data on fast recovery disk than with conventional arrays.
Remote Replication of Backup Data Providing Automated
Disaster Recovery Protection
With the DXi4700, users can transmit backup data from a remote site to a central, secure location to reduce
or eliminate media handling. DXi™-Series replication is asynchronous, automated, and operates as a
background process.
Enterprise Features Provide Secure Repository
The DXi4700 features Capacity-on-Demand scalability from 5 TB up to 135 TB. The DXi4700 offers three
options for storage presentation:
lDXi4700 NAS Configuration - Presents storage as NAS shares (CIFS/SMB, NFS, Application
Specific) or OST storage servers.
lDXi4700 VTL Configuration - Presents storage as VTL (virtual tape library) partitions.
lDXi4700 Multi-Protocol Configuration - Ability to present storage as NAS shares (CIFS/SMB, NFS,
Application Specific), OST storage servers, and VTL (virtual tape library) partitions.
DXi Accent distributes deduplication between the DXi4700 and the backup server to accelerate backups
over bandwidth-constrained networks. Compatibility with Quantum's vmPRO software provides
consolidated support for backup of physical and virtual servers.
In addition, DXi4700 systems optionally support Data-at-Rest Encryption to secure all data stored on the
DXi4700. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi4700
cannot be read using another system or device.

Note: Quantum recommends installing the DXi4700 system in a controlled or restricted area and
using strong, private passwords to prevent access by untrained personnel. In addition, Quantum
recommends that system installation be performed only by qualified IT personnel with strong
networking experience.
Determining the DXi4700 Model
You will need to determine if the DXi system is a DXi4700 G1 or DXi4700 G2. Model information is located
on the pull-out information tag on the front of the Node (see Figure 1 below).
lThe DXi4700 G2 information tag includes “G2” in the part number (see Figure 2 on the next page).
lThe DXi4700 G1 information tag does not include “G1” in the part number (see Figure 3 on the next
page).

Data Reduction
Data reduction is the process of reducing the amount of storage capacity required to store your data. The
DXi4700 systems provide two techniques to optimize the storage space required on your system:
lData Deduplication below
lCompression on the next page
Data Deduplication
The DXi-Series disk backup and replication systems use Quantum’s patented data deduplication technology
to dramatically increase the role that disk can play in data protection. With DXi-Series solutions, users can
retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays. This advantage
allows IT departments to cost-effectively retain months of backup data on disk for faster, more reliable
restores and more data recovery points. Quantum’s innovative implementation of this core technology
means that users do not have to compromise on performance to take advantage of extended retention
capability. Inline data flow provides streamlined deduplication that offers a maximum combination of total
system performance, manageability, and value.

Chapter 1: System Description
Space Reclamation
Quantum DXi4700 User’s Guide 20
Quantum's deduplication technology uses a sub-file, variable-length approach to identify redundant blocks
in a data stream—blocks that have appeared before in the same dataset or in datasets processed at an
earlier time. When a block appears that has already been stored, the DXi system inserts a reference pointer
to the earlier instance of the data segment instead of storing another copy. The result is a dramatic reduction
in the storage capacity needed to store the data set, and a similar reduction in the bandwidth needed to
replicate deduplicated data sets over a network.
Compression
The DXi4700 systems use compression technology after duplicate blocks have been identified and replaced
as part of the deduplication process. With compression, unique data that has been through the data
deduplication process can be compressed at a typical ratio of approximately 2:1. This enables you to
maximize the storage capacity of your system.
Space Reclamation
The space reclamation process performs multiple functions on the DXi4700.
When data is deduplicated it is stored in a block pool—a pool of all unique data blocks that were captured
during the data deduplication cycle. When subsequent backup jobs occur, the data deduplication engine
searches for new data entering the DXi and uses a variable length compression algorithm to compare new
data to existing data in the block pool. Unique blocks are added to the block pool and known blocks are
indexed.
The space reclamation function searches the blockpool for data blocks that are not referenced by any
pointers (that is, the files associated with the block have been expired and removed). Once such a data block
is identified, the block is removed to make the space reusable.
For correct system operation, space reclamation must be run at regular intervals (at least once a week).
Quantum recommends creating a schedule to automatically run space reclamation (see ).
It may be beneficial to schedule space reclamation for a time when other operations are not normally being
carried out. Therefore it is important to know when to schedule the space reclamation process. As best
practice it is recommended that this process commences at least two hours after your backup job has
completed on a daily basis. It is far more efficient to process a day’s worth of new data than a week’s worth.
Remote Replication
Today most backup occurs on isolated devices, making it difficult to deploy disk backup when disaster
recovery protection is required. DXi-Series solutions use data deduplication and replication to decrease by
up to 50 times the bandwidth required to move backup data over networks and between sites. This dramatic
