Ensure that the following system requirements
for the desired deployment modes are met:

NOTE: For any
of the mentioned deployment modes, ensure that you reserve sufficient
amount of memory resources to the OMIVV virtual appliance by using
reservations. See vSphere Documentation for steps about reserving
memory resources.
You can select an appropriate deployment mode to scale OMIVV to match
the number of nodes in your environment.
Steps
In the APPLIANCE MANAGEMENT page,
scroll down to Deployment Mode.
The configuration values of the deployment
mode such as Small, Medium, or Large is displayed and by default, the
deployment mode is set to Small.
Click Edit if you want to update the deployment
mode based on the environment.
In the Edit mode, select the desired deployment
mode after ensuring that the prerequisites are met.
Click Apply.
The allocated CPU and memory are verified
against the required CPU and memory for the set deployment mode and
either of the following situations happen:
If the verification
fails, an error message is displayed.
If the verification
is successful, the OMIVV appliance restarts and the deployment mode
is changed after you confirm the change.
If the required
deployment mode is already set, a message is displayed.
If the deployment mode is changed, confirm the changes, and then
proceed with rebooting the OMIVV appliance to allow the deployment
mode to be updated.
Results
NOTE: During the OMIVV appliance
boot up, the allocated system resource is verified against the set
deployment mode. If the allocated system resources are less than the
set deployment mode, the OMIVV appliance does not boot up to the login
screen. To boot up the OMIVV appliance, shut down the OMIVV appliance,
update the system resources to the existing set deployment mode, and
follow the Downgrade deployment mode task.
Downgrading

Steps
Log in to the Administration Console.
Change the deployment mode to the desired level.
Shut down the OMIVV appliance and change the system resources to
the desired level.
Power on the OMIVV appliance.
