Chapter 1: System Description
Overview
Quantum DXi6900 User’s Guide 16
Overview
The DXi6900 is Quantum’s Enterprise disk backup solution that integrates data deduplication, replication,
and direct tape creation technology to connect backup and disaster recovery protection across distributed
corporate environments. The DXi6900 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. Scalable to 510 TB (DXi6900) or 544 TB
(DXi6900-S) usable capacity, the DXi6900 is designed for larger sites and corporate data centers.
Advanced Data Deduplication Increasing Disk Retention
for Backup Data
The DXi6900 leverages Quantum’s patented data deduplication technology to dramatically increase the role
that disk can play in the protection of critical data. With theDXi6900 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 DXi6900, 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
With up to 510 TB (DXi6900) or 544 TB (DXi6900-S) usable capacity, the DXi6900 supports large-scale
Enterprise environments. Presentations include both VTL (Fibre Channel) and NAS (CIFS and NFS) as
well as Symantec OpenStorage (OST) and Oracle® Recovery Manager (RMAN) APIs. Integrated tape
creation writes physical media directly over dedicated Fibre Channel connections, and supports ISV direct
tape creation in NetBackup, Backup Exec, NetWorker, Oracle Secure Backup, and ASG-Time Navigator.
DXi Accent distributes deduplication between the DXi6900 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, DXi6900 systems optionally support Data-at-Rest Encryption to secure all data stored on the
DXi6900. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi6900
cannot be read using another system or device.
Note:DXi6900-S systems support Data-at-Rest encryption to secure all data stored on the Array
module (RBOD) and Expansion module (EBOD) bulk data storage disks.

Note:Quantum recommends installing the DXi6900 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 DXi6900 Model
You will need to determine if the DXi system is a DXi6900 G1, DXi6900 G2, or DXi6900-S. Model
information is located on the pull-out information tag on the front of the Node (see Figure 1 below).
lThe DXi6900-S information tag includes "S" in the part number (see Figure 2 on the next page).
lThe DXi6900 G2 information tag includes “G2” in the part number (see Figure 3 on the next page).
lThe DXi6900 G1 information tag does not include “G1” in the part number (see Figure 4 on the next
page).

Chapter 1: System Description
Data Reduction
Quantum DXi6900 User’s Guide 20
Data Reduction
Data reduction is the process of reducing the amount of storage capacity required to store your data. The
DXi6900 systems provide two techniques to optimize the storage space required on your system:
lData Deduplication below
lCompression below
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.
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 DXi6900 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 DXi6900.
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
