(Optional) Add the Snapshot Manager extension
The Snapshot Manager extension serves the purpose of scaling the capacity of the Snapshot Manager host to service a large number of requests concurrently running on the Snapshot Manager server at its peak performance capacity. You can install one or more Snapshot Manager extensions on-premise or in cloud, depending on your requirements to run the jobs without putting the host under additional stress. An extension can increase the processing capacity of the Snapshot Manager host.
The Snapshot Manager extension can have the configuration same or higher as the Snapshot Manager host.
Supported Snapshot Manager extension environments:
VM based extension for on-premise
Cloud based extension with managed Kubernetes cluster
