Optimizing Data for Capacity
Optimizing data for capacity in vCenter Operations Manager involves finding opportunities for resource
optimization and cost savings.
Determine How Efficiently You Use the Virtual Infrastructure
Determining the efficiency of the vCenter Operations Manager virtual infrastructure involves investigating
the optimal, waste, and stressed virtual machines.
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the arrow under the Efficiency badge to expand the detailed view.
The Efficiency pane displays the subbadges for Reclaimable Waste and Density.
What to do next
Examine the Reclaimable Waste and Density subbadge colors to identify whether resources are underused
or partially consolidated.
Depending on your findings, you can investigate possible opportunities to improve efficiency.
Identify the Consolidation Ratio Trend for a Datacenter or Cluster
The consolidation ratio trend of a datacenter or cluster helps you understand the behavior and performance
of your virtual machines and applications.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the arrow under the Efficiency badge to expand the detailed view.
3 In the Density pane, compare the consolidation ratio trend in the VM : Host Ratio and the vCPU : CPU
Ratio graphs.
If the ratios are below the optimal rate, the resource consolidation is low.
What to do next
To further investigate opportunities to optimize resource consolidation, click the Views tab under the
Planning tab.
Determine Reclaimable Resources from Underused Objects
Determining reclaimable resources in vCenter Operations Manager involves identifying the objects that are
underused.
Reclaimable waste is calculated for each resource type like CPU, memory, and disk, for each object in the virtual
environment.
