Hi Boris,

The best practice would be not to use bus sharing, as snapshots are not supported for these kind of disks. Usually people use SQL Server AlwaysOn instead of clustering it via Failover Cluster feature. Please review this topic for more info.

Thanks!

I was testing Server 2016 Storage Replica to possibly replaced some old DFSR, but unfortunately that also has to use bus sharing so my plans have been scuppered :(

Hi Vitaliy,

thanks for your reply, but unfortunately AlwaysOn is not the same as a "real" FCI, in my opinion AlwaysOn is like a narrow gauge cluster without the need for shared storage.

An FCI covers everything about the SQL instance - databases, logins, certificates, policies, agent jobs, and more. Whether you have two databases or hundred databases, they will all go together. An AvailabilityGroup will only fail over the data in the databases that are in the group. You must separately manage everything else. The more replicas you add, the more complex management becomes.

maybe this is one reason I'm considering to move away from VMware to Hyper-V because there are snapshot capable shared VHDX available

Ok, thanks for clarification, makes sense. If you're considering VHDX, then please take a look at this topic > Backing up a Windows Failover Cluster with Shared vhdx?
