yes, you should create quorum witness as best practice. If you do not have quorum witness, there will be 50% probability that your whole cluster fails when one node goes down. Please refer below official doc: learn.microsoft.com/en-us/azure-stack/hci/concepts/quorum#examples
@@arslanov1886thank you very much for the prompt and detailed reply. our environment is on a vxrail. what will be the best witness to use? will a file share witness created on a nas storage work. have you got any good videos for configuring the windows failover cluster. if yes, please share.
As long as you have a constant and stable network between your servers and witness, you can choose any type of witness. There are other small points. Please refer below: learn.microsoft.com/en-us/windows-server/failover-clustering/manage-cluster-quorum#witness-configuration Please make sure that the witness is in another server. I do not have videoes but I would follow the below good docs: Step 1 learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/failover-cluster-instance-prepare-vm?view=azuresql&tabs=single-subnet Step 2 learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/failover-cluster-instance-azure-shared-disks-manually-configure?view=azuresql
