Greetings,

I'd heard rumors of issues in high file count environments -- the recommendation was not to go there yet. Does anyone have more information about this?

Thanks for the feedback!  Aside from universal ONTAP version support, are there any other upsides to using XDP?  Depending upon which NetApp rep I ask I get differing answers on whether XDP is file-level copy or block-level.  

But again, thank you for the answers!

You should notice less performance impact on the source and as little bit more on the destination. After the update transfer there are some housekeeping steps that post process on the destination which uses resources.

We've converted all our snapmirrors to XDP. It is slighltly slower
but the benefit of not having to worry about source/destination
versions is worth it for us since we have a bunch of clusters cross
mirroring different volumes and with DP we had to upgrade a dozen
clusters at the same in order to not break snapmirror.
