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.
