NetApp Deduplication for FAS and V-Series Deployment and Implementation Guide
Here are some additional considerations with regard to max volume sizes for deduplication:
Once an upgrade to Data ONTAP 7.3.1 is complete, the new maximum volume sizes for Data ONTAP
7.3.1 will be in effect.
If considering a downgrade or revert, it is highly recommended that NetApp Global Services be
consulted for best practice.
During a revert from Data ONTAP 7.3.1 to an earlier version of Data ONTAP with smaller volume limits,
volumes should be within the limits of the lower version of Data ONTAP. If downgrading to 7.2.5.1, you
cannot simply resize the volume. Instead, a new flexible volume that is within the max vol size limits
must be created, and the data must be moved to that volume prior to the downgrade.
If a downgrade has occurred from 7.3.1 to 7.3.0, where the volume size was greater than the 7.3.0
volume size limit, then the volume will go offline. If this has occurred, contact NetApp Global Services
for assistance with bringing the volume back online.
WHAT’S SUPPORTED WITH DEDUPLICATION
The following NetApp features are supported with deduplication:
Deduplication is supported on the R200 systems and on all FAS and V-Series systems with the
NearStore option license.
Only flexible volumes are supported. Traditional volumes are not supported.
Starting with Data ONTAP 7.3.1, SnapLock
®
volumes are supported with deduplication in both
enterprise and compliance modes.
LUNs are supported with deduplication.
SnapMirror
®
is supported with deduplication (both qtree SnapMirror and volume SnapMirror).
SnapMirror sync mode is not supported with deduplication.
SnapVault on the source volume is supported with deduplication.
Starting with Data ONTAP 7.3, SnapVault on the destination volume is supported.
Starting with Data ONTAP 7.3, Open Systems SnapVault is supported.
Starting with Data ONTAP 7.3.1, stretch MetroCluster is supported with deduplication.
Starting with Data ONTAP 7.3.1, fabric MetroCluster is supported with deduplication.
Starting with Data ONTAP 7.3, the V-Series product line is supported with deduplication.
Starting with Data ONTAP 7.3, MultiStore
®
is supported with deduplication. Starting with Data ONTAP
7.3.1, deduplication commands are also available from within each MutiStore vFiler
™
unit.
FlexShare
™
is supported with deduplication.
NDMP dump is supported with deduplication.
2.2 INSTALLING AND LICENSING DEDUPLICATION
Deduplication is included in Data ONTAP and just needs to be licensed. Add the deduplication license by
using the following command:
license add <a_sis license key>
To run deduplication on any of the FAS platforms, you also need to add the NearStore option license:
license add <nearstore_option license key>
There is no charge for either license; contact your sales representative to obtain the licenses.
DEDUPLICATION LICENSING IN A CLUSTERED ENVIRONMENT
Deduplication is a licensed option behind the NearStore option license. Both nodes must have the
NearStore option licensed. Deduplication must be licensed on both nodes of the cluster as well.
