Overview of DSM Architecture
•
The DSM subsystem environment
The subsystem environment consists of HP subsystems, business applications,
and their objects. HP subsystems that have an SPI management interface are part
of the DSM subsystem environment. Your business applications can also be in the
subsystem environment if you write SPI management interfaces to these
applications. A management interface allows a subsystem or application to be
managed programmatically by a management application. The subsystem
environment also includes objects, the resources controlled by subsystems.
•
The DSM management services
The DSM management services are software products that support the
programmatic interface between the applications and tools in the operations
environment and the subsystems and objects in the subsystem environment. The
DSM applications use these services. You also use these services for the
management applications you write.
These services include:
•
The Event Management Service (EMS), providing event collection, logging,
and distribution facilities
•
DSM Template Services, providing text generation from tokenized SPI
messages often used to generate text for an operator console from event
messages
•
The Distributed Name Service (DNS), providing mapping between logical
device names and physical device names
