Planning clusters

Before implementing a high-availability solution, you must ensure that you met all prerequisites for clusters.

Hardware requirements for clusters
To implement a high-availability solution, you need to plan and configure a cluster. A cluster groups systems and resources in a high availability environment.
Software requirements for clusters
In order to use clustering, you must have the correct software and licenses.
Communications requirements for clusters
Use any type of communications media in your clustering environment as long as it supports Internet Protocol (IP).
Performance planning for clusters
When changes are made to a cluster, the overhead necessary to manage the cluster can be affected.
Planning advanced node failure detection
Advanced node failure detection function can be used to reduce the number of failure scenarios which result in cluster partitions.
Planning checklist for clusters
Complete the cluster configuration checklist to ensure that your environment is prepared properly before you begin to configure your cluster.
