For any of the mentioned deployment modes, ensure that you reserve sufficient memory resources to the OMIVV appliance using reservations. See vSphere documentation for steps about reserving memory resources.
Ensure that the following system requirements for the required deployment modes are fulfilled by assigning these resources to the VM containing OMIVV:

NOTE: MX chassis firmware update feature is supported only on medium, large, and extra large deployment modes.
You can select an appropriate deployment mode to scale OMIVV to match the number of nodes in your environment.
On the
APPLIANCE MANAGEMENT page, scroll down to
Deployment Mode.
The configuration values of the deployment mode such as
Small,
Medium,
Large, and X Large are displayed. By default, the mode is set to
Small.
To edit a deployment mode based on an environment, click
Edit.
In the
Edit mode, ensure that the prerequisites are fulfilled and select the required deployment mode.
Click
Apply.
The allocated CPU and memory are verified against the required CPU and memory for the set deployment mode.
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 the appliance is restarted to enable the deployment mode to be updated.
NOTE: During the OMIVV appliance bootup, the allocated system resources are verified against the set deployment mode. If the allocated system resources are less than the set deployment mode, the OMIVV appliance does not boot to the login page. To boot the OMIVV appliance, close the OMIVV appliance, update the system resources to the existing set deployment mode, and complete the
downgrade deployment mode task.
Downgrade deployment mode
Log in to the Administration Console.
Change the deployment mode to the required level.
Shut down the OMIVV appliance and change the system resources to the required level.
Turn on the OMIVV appliance.
