The deployment of Arcserve RHA components depends on the size of your IT enterprise network and your replication and HA needs. However, there are certain guidelines that you should follow when designing your Replication and High Availability environment and deploying the different components on a Windows platform. The following section provides information regarding an efficient deployment of Arcserve RHA components.
The following illustration shows a typical deployment of Arcserve RHA components:
The Control Service must be able to connect to all Master and Switchover Replica servers. It is not mandatory that the Control Service have a direct connection to each non-Switchover Replica server in the scenarios.
We recommend installing the Control Service on a separate server. If you are working with High Availability scenarios, do not install the Control Service on either the Master or the Replica hosts.
You can install the Control Service on your local workstation. However, you should be aware that if this workstation is disabled or offline, you will not be able to monitor or manage your scenarios.
The Engine must be installed on each Master and Replica server that participates in the defined scenarios.
This component can be opened from any workstation that has a browser and network connectivity to the Control Service.
This component can be opened from any workstation that has Windows PowerShell and network connectivity to the Control Service.
