Dell 7.6 manual Omci Architecture, Smbios

OMCI uses a variety of data sources resident on the client system which includes:

•Microsoft Win32 WMI providers

•SMBIOS

•Device drivers

•Operating system registry

•Operating system Application Programming Interfaces (APIs)

•WMI repository

OMCI Architecture

The OMCI architecture is based on a layered model that is tightly integrated with the Microsoft WMI stack as shown in Figure 1-1.

•WMI application layer — Consists of management applications such as Dell Client Manager, Dell OpenManage Client Administrator (OMCA), and other standards-based management tools and WMI applications such as Microsoft SMS, LANDesk, and so on. This layer is not a part of OMCI and the applications are consumers of systems management data supplied from the client by OMCI. These applications request client information and receive client alerts through the CIMOM.

•Dell WMI provider — Lies beneath the CIMOM and contains two CIM providers which register with the CIMOM. When the CIMOM receives a request for information, it routes the request to the appropriate provider. Both Dell and Microsoft providers exist in this layer, and they provide information on system devices. The providers send management application requests from the CIMOM to the data router.

•Data router — Collects information from system components in the data provider layer and passes the information up to the Dell WMI provider layer, which then presents it to the CIMOM.

•Data provider — Provides data to the data router. When it receives a request from the data router, the data provider queries the client system's hardware, drivers, and operating system to determine the available instrumentation. It then applies all platform and customer overrides to the data before returning it to the data router.
