About Infrastructure Management Server (IMS)
Each Resiliency Manager requires one or more Infrastructure Management Servers (IMSs). An IMS discovers and monitors assets within a data center. You use the web console to add the asset infrastructure to Resiliency Platform so that assets can be discovered and monitored by an IMS.
The asset infrastructure can include objects such as hosts, virtualization servers, and enclosures (storage arrays).
The IMS sends information about the assets to the Resiliency Manager so that the Resiliency Manager can manage the assets. Management operations on assets (for example, starting or stopping virtual machines) that you initiate from the web console are carried out by the IMS.
If there are multiple data centers in different geographical locations, a separate IMS is deployed and configured for each geographical data center location.
Each IMS connects to only one Resiliency Manager at a time. If a Resiliency Manager failure occurs, an IMS can automatically connect to another Resiliency Manager within the same domain.
You can also configure multiple Infrastructure Management Servers in the same data center. For example, to achieve scale, you can add a separate IMS for a separate business unit such as Human Resources or Finance. More than one IMS can be managed by the same Resiliency Manager.
