Veeam ONE’s advanced analysis takes the guesswork out of capacity planning. Heterogeneous capacity planning helps you safely add or remove VMs or hosts from your infrastructure during deployment projects by forever replacing risky manual calculations with fully automated “what-if” planning, making for worry-free system changes and upgrades. You can manage multiple deployment projects at the same time giving you the ability to reserve resources, plan hardware upgrades and review resource utilization during possible DR situations.
