Right-Sizing Capacity for Stress-Free Demand and Value
Performance management and capacity planning vary across organizations and environments. Because the
demand for capacity uctuates in each environment, the top contenders for priority often include high
eciency versus low risk of poor performance. To plan and manage your capacity needs and intelligently
calculate the capacity of your resources, vRealize Operations Manager uses sophisticated models.
With the capacity calculations in vRealize Operations Manager, you can use various sophisticated models to
produce practical correlations between objective measured metrics and subjective goals of acceptable
performance and eciency.
