• Distribute cluster-wide information
  Learn about the security implications of using and managing cluster-wide information.
• Maintain user profiles on all nodes
  You can use two mechanisms for maintaining user profiles on all nodes within a cluster.
• Considerations for using clusters with firewalls
  If you are using clustering in a network that uses firewalls, you should be aware of some limitations and requirements.
