Visualizing Headroom and Underutilized Racks
35 Managing physical grouping of infrastructure devices in OpenManage Enterprise Power Manager
7 Visualizing Headroom and Underutilized Racks
This section is about how power and space headroom can be observed in physical groups. This helps to
determine current density of infrastructure devices in a data center. The information also helps in data
center planning activities by clearly highlighting the available power and space at each group hierarchy
level.
7.1 Visualizing power and space headroom in Group Details
1. Click PLUGIN GROUPS > Physical Hierarchy > Rack.
2. Click Group Details tab, and then click Headroom tab.
3. Headroom has two sections that show the Power Headroom and Space Headroom.
The Power Headroom shows the used and available power capacity. And, the Space Headroom
shows the used and available space capacity rack.
