Hi Experts,
I am setting up a stretched cluster with windows 2008 r2 and sql 2008 r2 in a 2+ 1 mode. So a local 2 node cluster is already there in primary site.Needs to be extended to the DR site as a node addition. Storage for syncronous replication would be EMC. I understand that there will be some impact on the performance of the SQL server due to the syncronous replication. Is there any link/whitepaper available to showcase the impact that would be there due to the replication and the factors to be taken into consideration to mitigate the impact
