Correction (August 25, 2026): This article previously treated a 90-day Time Remaining threshold as if it also configured 90 days of historical input. Those controls have different meanings. The original procedure has been retired so it cannot be followed accidentally.
Use the corrected follow-up instead:
Using a 90-Day Planning Horizon Correctly in VCF Operations
The follow-up separates three independent goals:
- Alerting when capacity is projected to run out within a future planning period.
- Choosing how much historical demand the projection may consider.
- Setting the future horizon used for VM Recommended Size calculations.
It also corrects the earlier maintenance-window advice. For capacity forecasting, use the product’s projection reset and time-range exclusion controls when you need to disregard anomalous history; do not assume that an alert-maintenance schedule is equivalent to a historical-data exclusion.
The current explanation is based on Broadcom’s capacity guidance and KB 437777, including risk levels, historical-data settings, HA reservations, recalculation behavior, and the fact that a projection reset does not delete stored historical metrics.
