After adding new workloads, why is Overall Runway below 365 days and the scenario still...

Nutanix Capacity Planning and Runway calculations analyze CPU, memory, and storage growth trends independently. The “Overall Runway” metric reflects the shortest runway across these three resources. The Capacity Planning documentation explains that “the scenario result may show the cluster in a healthy state if the most critical resource remains sufficiently available, even when the overall runway falls below longer-term thresholds.”

Storage is often the dominant factor in determining long-term viability. If the storage runway remains strong, the system may indicate that the environment is in good shape even though the overall runway appears shorter due to CPU or memory projections. Because the question refers to the scenario still indicating a good cluster state, the most accurate interpretation is that storage runway remains healthy, and thus the system does not consider the cluster at risk.
