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.
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.
o The location needs to be on a dedicated / non-removable volume.
2. OpenStorage devices:
o The OpenStorage device requires a plug in or connector which is purchased from the devices vendor.
NOTE: Basic Requirements for any installation of the Deduplication Option on ether types for storage:
• 8 GB RAM, for each 5 TB of deduplicated data.
The required amount of RAM can be determined by an equation
• 1.5 GB x N (the number of TB’s of deduplicated data to be stored). The max amount of stored data = 32 TB.
1.5 GB x N= GB’s of RAM
