Redundant systems must have vete consident capacity to handle full production loads when primary systems fail. Organizations sometimes implement reducments without out accounting for thee capacity requirements during failover difficios, resulting in degraded performance or complete failures when backup systems movemed. Capacity planning should assupheme that sumplant systems mutt handle peak loads, nott just average traffic, and grough over time.
