I have configure Microsoft failover clustering as Stretch clustering. I have two sites in the stretch cluster, each site has two nodes and one shared storage. Thus far I have Storage replica enabled and failover is seemless.

I want to know if I can add a third site with two nodes and a third shared storage into the existing stretch cluster and have data replicate and failover without issue? Reading the guides it seems to not be however, I wanted to see someone has actually done this.

    Hi,

    Storage replication in Stretched cluster is one to one correspondence, cluster disk 1 in site 1 already configured SR to cluster disk 1 in site 2 is unable to configure SR to site 3 anymore. However, it might be possible if we have cluster disk 2 in site 1 configure SR to cluster disk 2 in site 3.

    Not like Hyper V replication that can stretch replication to the third one.

    Thanks for your time!
    Best Regards,
    Anne
