NetApp Deduplication for FAS and V-Series Deployment and Implementation Guide
1.4 GENERAL DEDUPLICATION FEATURES
Deduplication is enabled on a per flexible volume basis. It can be enabled on any number of flexible
volumes in a storage system. It can be run one of four different ways:
Scheduled on specific days and at specific times
Manually using the command line
Automatically, when 20% new data has been written to the volume
Automatically on the destination volume, when used with SnapVault
®
Only one deduplication process can run on a flexible volume at a time.
Up to eight deduplication processes can run concurrently on eight volumes within the same NetApp storage
system.
Beginning with Data ONTAP 7.3.1, deduplication checkpoint restart will allow a deduplication process that
was interrupted to continue from the last checkpoint. Prior to Data ONTAP 7.3.1, an interrupted
deduplication process would result in a restart of the entire deduplication process. If the system is restarted
while deduplication is in process, when the system is once again online, the deduplication process will
automatically restart from the last checkpoint.
2 CONFIGURATION AND OPERATION
This section discusses what is required to install deduplication, how to configure it, and various aspects of
managing it. Although it discusses some basic things, in general it assumes both that the NetApp storage
system is already installed and running and that the reader is familiar with basic NetApp administration.
2.1 REQUIREMENTS OVERVIEW
Table 1 specifies the hardware and software required to run deduplication.
