Hi, For Veritas Cluster 5.0.... We also have Storage Foundation for Oracle.
Currently we use direct connect cables between the two nodes in our Veritas Cluster for the "heartbeat". However, we are switching to new systems and running the direct connect cables is more difficult than it used to be. So, we are considering the use of two VLANs for this purpose. I believe that traffic on these two VLANs is limited to only Cluster heartbeat connections (though not just ours). What is the downside of using VLANs for the heartbeat? In what scenarios could problems develop? I'm concerned that if our network has a serious problem and "goes down" that each Node in the Cluster might be isolated and both Nodes import the disk groups, mount volumes, etc and thus data corruption. Is data corruption a possibility if the entire network goes down or in other scenarios? Does Veritas also use "quorum" or any other methods to protect against split brain induced damage? Thanks
