To perform a failover test, take the following steps:
Analyze the system and your needs, and use that information to set up performance benchmarks you expect the system to meet in the event failover is necessary.
Set up a plan for your test. Ideally, you want to arrange for several tests—one for each of a variety of situations.
Run each test, taking note of how the system performed.
Analyze the performance data and compare it to the benchmarks in step 1.
