SQL Server 2008 R2 Cluster

Hi,

Please go through the image.

I found this on one of our customer sql server 2008 R2 cluster. This is Active/Passive. In this image i can see 2 nodes are mentioned as Preferred owners? What does it means? is there any impact?

Hi,

These nodes on preffered onwers list basically are on the front in the failover to list. It means that even if your cluster has more nodes these will be taken first for failover. If these nodes fail your resource will failover to other nodes. It sets the order in which resource will failover if all nodes are on the list, however in two node cluster resource may failover only to other node so it doesn't make so much difference.

Some failover scenarios for 3 and more node clusters:
