A clear understanding of your high availability objectives will quickly help you to define your hardware requirements and design your system. Use the following questions as a guide for general planning:

  1. What applications must continue to be available in the event of a failure?

  2. What system resources (processing power, networking, SPU memory, disk space) are needed to support these applications?

  3. How will these resources be distributed among the nodes in the cluster during normal operation?

  4. How will these resources be distributed among the nodes of the cluster in all possible combinations of failures, especially node failures?

  5. How will resources be distributed during routine maintenance of the cluster?

  6. What are the networking requirements? Are all networks and subnets available?

  7. Have you eliminated all single points of failure? For example:

    • network points of failure

    • disk points of failure

    • electrical points of failure

    • application points of failure
