About Performance and Tuning for Clustered Installations

Load balancing and high availability are the two main benefits for clustering. You must determine the necessary hardware size, processing requirements, and service level for effective clustering.

Clustering involves these hardware sizing questions:
  • What equipment satisfies processing requirements?
  • What equipment satisfies service level agreements?
These questions relate to the two main benefits for clustering: load balancing and high availability. Multiple approaches can meet these objectives, and you need to understand the reasons behind considering clustering, and to evaluate alternatives to clustering to address these objectives. You should answer the following questions:
  • What are the processing or throughput requirements?
  • What are the service level or availability objectives?

You must answer both of these questions at the complete system level, and not just at the level of the application servers, since many factors can affect the final design.
