I am currently running a 4 node Server 2016 Hyper-V cluster storage is provided by a DELL MD3200 SAN normal concepts for CSV volume on NTFS are in place as previously nodes where 2012R2 and 2008R2 prior. My main question is I am going to be adding another
SAN DELL MD3420 and I have been wondering whether to use REFS for the file system for VM’s situated on this SAN.

I came across a Veeam article advising moving to this scenario however I would like to get the opinion of you all.

Regards

Chris
