Using Offload features in a VM

jenoptik — Wed, 04 Jun 2025 22:15:05 GMT

Hi everyone,

I got the task to transfer the content of a iscsi LUN to another LUN due to LUN geometry/sizing issues.

Are there any netapp offloading functions i can use in a VM (Windows) to accelerate the copy from one lun drive to another lun drive?

It would be nice to keep the work on the filer and don't stress the network for reading/writing.

Thx 4 any answer.

If you're using a newer version of clustered Data ONTAP, SMB 3, and a compatible version of Windows, then it will use ODX to transfer data...this works SMB3-to-SMB3, LUN-to-LUN and LUN-to-SMB3 (or vice-versa). Some more info is available here.

Be sure to give the "File Access and Protocols Management Guide" for your Data ONTAP version a read just to ensure you understand what the requirements are and what's going on with your data. For 8.2 there is a section titled "Improving Microsoft Remote Copy Performance" which specifically addresses ODX.

Hope that helps.
