Windows 2016 General Purpose File Server with Windows 7 Clients

Hello everybody,

I'm missing some experience concerning SMB 2.1 access for newer Versions 2012 R2+ Failoverclusters.

Several industry machines using Windows 7 are planned to store logs on a two-node Server 2016 general purpose fileserver cluster. The machines access the cluster via UNC-Path containing the virtual IP of the cluster, e.g. \\logs

My oppinion at the moment is, that transparent failover is only possible with SMB3 Clients.

How is the failover managed accessing with SMB 2.1? Will there be any restrictions using SMB 2.1?

Thanks in advance & best regards

    Hi @Johannes Tröster ,

    To be able to use SMB Transparent Failover, both the SMB client computer and the SMB server computer must support SMB 3.0, which is introduced in Windows 8 and Windows Server 2012.

    Computers running lower SMB versions, such as 1.0, 2.0 or 2.1 can connect and access data on a file share that has the continuously available property set, but will not be able to realize the benefits of the SMB Transparent Failover feature.

    SMB Transparent Failover is one of the key features in the feature set introduced in Server Message Block (SMB) 3.0. SMB 3.0 is new in Windows Server 2012 and Windows 8.

    So, SMB Transparent Failover only possible with SMB3 Clients. Please check the following article for detailed information:

    How is the Failover handled with SMB 2.1 Clients? Will there be connection losses e.g. if a file is opened writing logs?
