Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Click the Analysis tab.
2 In the heat map gallery, narrow the scope from the drop-down menu to display the datastore waste.
Option Action
Focus Area
Select Storage.
Smallest Box Shows
Select Host.
Description
Select For each datastore, which hosts currently have the highest I/O usage
and latency?
3 Click theFor each datastore, which hosts currently have the highest I/O usage and latency? view.
4 In the heat map, point to each datacenter area to view the latency statistics.
What to do next
Identify the host and datastore pair with the highest latency. Then determine how many hosts are using the
datastore. If only one VM is using the datastore, or if more than one is but none of the others have high latency,
there might be a problem with the host. Find out which VMs are on the host and what their storage usage is.
If there are multiple hosts and they all are red, there might be a population pressure problem on the datastore.
If this is the case, you should consider relocating some VMs.
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.
