Viewing system airflow graph

iDRAC provides an accurate calculation of the server’s Cubic Feet Per Minute (CFM) value. The CFM value is a measure of the

net system airflow to the servers. This value is used in Power Thermal Aware Scheduling (PTAS), balancing the data center

workload, efficient server utilization, and thermal management from a rack level. CFM or the system airflow graph is useful from

a group level (data center, room, aisle, rack, or custom groups). The values are collected only from the devices that support this

feature.
