Prior to using Deduplication get an accurate snapshot of your system requirements. The first steps include determining what supported deduplication storage device and the type of deduplication you are going to use prior to installing the Deduplication Option.
Use the Hardware Compatibility List to help establish the storage device type.

Storage Types:
There are currently two main options to choose from:
1. Backup Exec Deduplication disk storage devices:
o A 64-bit Backup Exec server.
o A Backup Exec server with either one quad-core processor or two dual-core processors.

NOTE: Basic Requirements for any installation of the Deduplication Option on ether types for storage:
