Planning a cluster

When planning a cluster, it is important to consider the performance and ability of your hardware. The cluster must have enough CPU power, memory, and disk space to handle the cluster traffic and the number of databases and replicas required.

As you plan your cluster, read the related topics to answer the following questions:

  • How many servers will you have in the cluster?
  • How many replicas will you have and where will they reside?
  • How will databases be distributed across servers to balance work load most effectively?
    Note: Managing and monitoring the cluster helps with workload balancing.
  • Will your cluster traffic need a private LAN?
  • Do you want to create your cluster over a wide area network?
  • Do you want to use fault recovery?

After the cluster is up and running, you can further balance the workload by setting a maximum number of users for each server and setting the availability threshold in a way that does not allow any server to become overloaded. You can track the cluster statistics to determine whether you need to make any changes to the cluster setup.
