Two node Clsuter
Support Failover Group
Failover group is including the resources that can be run on only one node at a time.
Application will be switch over to standby node at critical reource is failed in a failover group. The resources that included group are online only available node.
For example, user would like to run backup software on both nodes and be managed by the MCCS, backup software should be online on both nodes at the same time. You can use parallel group instead of failover group for this.
Support Parallel Group
Parallel group is a group of resources that are taken online on more than two nodes at the same time. Parallel group cannot failover.
The opposition of this is Failover Group. The group can be online on a node in a cluster within a failover group. However, when configured through parallel group, specified application can be online, monitored and terminated on the multiple nodes at the same time in a cluster.
For example, user would like to run backup software on both nodes and be managed by the MCCS, backup software should be online on both nodes at the same time. You can use parallel group instead of failover group for this.
Support Single Node Group
