ArcGIS Server (10.4+) cluster shared directory architecture

[Jay_Gregory]

Talking with Esri Support, and looking at documentation, it seems like the only supported architecture for a 2+ node ArcGIS Server cluster is using a network share for the config-store and other arcgisserver directories.  

I'm curious if anyone has had success with using Microsoft Windows Server Cluster Shared Volume (https://blogs.msdn.microsoft.com/clustering/2013/12/02/cluster-shared-volume-csv-inside-out/ ) instead?  

This is a feature of Windows Server 2008 R2 and above that can operate as another shared location between two or more servers - Esri support tells me a network share is the only supported architecture, but I'm curious if that's because they haven't fully tested Cluster Shared Volume, or actually found issues with using Cluster Shared Volume.  

Thanks!

can you share the outcomes of your Department's testing of CSV?

Sure.  I have had two instances of ArcGIS Server (virtual machines) running, using CSV for their shared config store and server directories for almost a year with zero failures or problems.  Obviously this requires robust infrastructure supporting CSV in order to be a success, so it doesn't prove that it's a superior strategy, just that ArcGIS Server doesn't seem to have a problem with it given our specific hardware and network configuration.
