Note: These options are saved in the resource container. To save your

specifications, make sure that you save the resource container. The total extra

resources that will be added to this resource container are the resources per host

multiplied by the number of hosts. Any calculations outlined in the When will I run

out? and How much more can I add? use cases consider these new resources as

available when using this resource container.

Overloaded hosts

In general, the best indicator of an overloaded datastore is the latency, or

response time, of read/write requests to the datastore. Outside of the storage

dashboard and alerts, you can determine when datastores will be overloaded

based on the current performance.

After adding your datastores to the chart, select a device latency graph or line to

see which datastores are experiencing the highest response time. You can also

plot IOPs for the datastore and the corresponding VMs to find the VMs that

generate the most IO.
