- In the Windows Failover Cluster, we have two or more cluster nodes, and these nodes communicate with each other on the UDP port 3343. Suppose due to some unforeseen circumstances; nodes cannot communicate with each other. In this case, all cluster nodes assume that they need to bring the resources online. Multiple nodes might try to bring the same resource online at the same time, but it is not possible to do so. This situation is called a Split-Brain situation, and we never want to be in this situation. We might face data corruption issues in this case.
We can avoid a split-brain scenario in Windows Failover Cluster by bringing the resources on a single node. Windows cluster achieve this by implementing a voting mechanism. Quorum checks for the minimum number of votes required to have a majority and own the resources

You deserves millions of subscribers
Videos are amazing and easy to understand from scratch....please cover Replication topic also....
Thank you.
I will cover replication, you may expect it in few weeks
Very useful channel 😊
Great video please make video for combine operation for failover cluster and always on
What if you only have 3 nodes running a SQL availability group with no shared disks. There are two that are in one subnet and one that is in another subnet?
Super brother
Hello, tysm for the video, I have a question, if my cloud witness is in Azure(storage account), do you know how I can find out within the cluster configuration, how to look at that resource to which I am connecting in Azure?
Good 👍
Great
Quarum is no need in Linux environment ?
Sir please post a video on SQL Server Failover Cluster installation also.
I don't have the machine setup in my home environment. But I will try to purchase machine from cloud and try to do it if possible. And unfortunately I cannot show it in my work environment due to security policies.
Do replication also 👌👌👌👌
