Data Reduction

Data reduction is the process of reducing the amount of storage capacity
required to store your data. The DXi3500 and DXi5500 systems provide
two techniques to optimize the storage space required on your system:

•

Data De-duplication

•

Hardware Compression

Data De-duplication

1

The DXi3500 and DXi5500 systems can reduce the amount of storage
capacity required through a data de-duplication process. The term data

de-duplication refers to the elimination of redundant data. During this
process, duplicate data is ignored, leaving only one copy of the data to be

stored. Indexing data is retained and used to restore the previously de-
duplicated data. Since only the unique data is stored on the system, the
amount of required storage space is reduced. For more information on

data de-duplication ennoblement, refer to

NAS Area

on page 40 and

Adding a Partition

on page 54.

Caution:

Server side software compression, encryption, or

multiplexing should NOT be used with the DXi3500/
DXi5500 system. This can impair the systems ability to de-
duplicate data.

Hardware Compression

1

The DXi3500 and DXi5500 systems are configured with the Optyon™
hardware-based compression card. With an Optyon card installed in
your system, unique data that has been through the de-duplication

process can be compressed at a ratio of 2:1. This enables you to maximize

the storage capacity of your system as well as increase overall backup
performance.
