Let's talk SMB protocol and failovers - what is your approach?

[ Edited ]

So, NetApp documenting really well what happening on the protocol level (http://www.netapp.com/us/media/tr-4100.pdf). and i assume doing large scale test for multiple software while knowing that "it shoulden't work" is not something anyone will invest time in...

 

But in real life what do you do or see? will appreciate if can you try and fill this template:

 

 

Estimate number of workstation:

ONTAP releases you have worked on:

Windows client versions:

Microsoft office versions:

Preferred failover time slot:

Are you notifying your users:

Are you asking the users to take any action:

Have you seen a user data loss as result of failover:

Have you seen consistent behavior or issues on the SMB clients upon failover:

Add your notes:

 

 

 

 

Thanks
