Requirements for using ODX
Before you can use ODX for copy offloads with your storage virtual machine (SVM), you need to be aware of certain requirements.
ONTAP version requirements
ONTAP releases support ODX for copy offloads.
SMB version requirements
ONTAP supports ODX with SMB 3.0 and later.
SMB 3.0 must be enabled on the CIFS server before ODX can be enabled:
Enabling ODX also enables SMB 3.0, if it is not already enabled.
Disabling SMB 3.0 also disables ODX.
Windows server and client requirements
Before you can use ODX for copy offloads, the Windows client must support the feature. Support for ODX starts with Windows 2012 Server and Windows 8.
The Interoperability Matrix contains the latest information about supported Windows clients.
Source volumes must be a minimum of 1.25 GB.
Deduplication must be enabled on volumes used with copy offload.
If you use compressed volumes, the compression type must be adaptive and only compression group size 8K is supported.
Secondary compression type is not supported.
