A chassis is a physical package that encloses other elements; in this case, the enclosed elements are the Celerra Data Movers and Control Station.
NASChassis is instantiated for each Celerra Network Server (NASChassis object) found during the discovery process.
The NASChassis is related to the FileServer and Host objects through the PackagesSystems relationship. The NASChassis is also related to remote Control Station Host objects through the ConnectedTo relationship. The ConnectedTo relationship reflects inter-Celerra device communication.
