Introduction 7

Introduction

The Dell™ OpenManage™ Client Instrumentation (OMCI) software enables

remote management application programs to access client system information,

monitor the client system status, or change the state of the client system; such

as shutting it down remotely. Through standard interfaces, OMCI exposes key

system parameters allowing administrators to manage inventory, monitor

system health, and gather information on deployed Dell client systems.

OMCI enables Dell client systems to be managed using the Common

Information Model (CIM) standard. CIM reduces your total cost of

ownership, improves security, and provides a holistic approach to managing

all devices in the enterprise, including clients, servers, storage, network, and

software devices.

CIM Overview

The CIM, created by the Desktop Management Task Force (DMTF) as part

of the Web-based Enterprise Management (WBEM) initiative, provides a

unified view of physical and logical objects in the managed environment.

CIM is a systems management protocol defined by industry standards.

The following are important CIM details:

• CIM is an object

oriented data model for describing management

information. CIM describes the way the data is organized, not necessarily

the transport model used to transport the data. The most prevalent

transport method is the Microsoft

Windows

Management

Instrumentation (WMI).

•CIM

capable management applications gather information from a variety

of CIM objects and devices, including client and server systems, network

infrastructure devices, and applications.

• The CIM specification details mapping techniques for improved

compatibility with other management protocols.

8Introduction

• The CIM data model abstracts and describes all elements in a network

environment. The CIM schema provides the actual data model

descriptions and arranges the network into a series of managed objects,

all interrelated and broadly classified.

• The CIM schema is defined by the Managed Object Format (MOF) file,

which provides a standardized model for describing management

information between clients in a management system. The MOF file is not

bound to a particular implementation, and it allows the interchange of

management information between many different management systems

and clients.

WMI Overview

WMI is Microsoft's implementation of CIM instrumentation. WMI supports

CIM and Microsoft-specific CIM extensions. The WMI management

infrastructure also includes the CIM Object Manager (CIMOM), which is

the interface and manipulation point for CIM objects and information.

It acts as a facilitator in gathering information and manipulating object

properties. OMCI provides data to WMI, which is the common interface

to WMI management applications. For more information, see "Windows

Management Instrumentation."

Data Sources Used by OMCI

OMCI contains the underlying driver set that collects system information from a

number of different sources on the client system, including the BIOS, CMOS,

System Management BIOS (SMBIOS), System Management Interface (SMI),

operating system, Application Programming Interfaces (APIs), Dynamic Link

Libraries (DLLs), and registry settings. OMCI exposes that information through

the CIMOM interface of the WMI stack and enables IT administrators to

remotely collect asset information, modify CMOS settings, receive proactive

notification of potential fault conditions, and be alerted to potential security

breaches.

Introduction 9

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

— C

onsists 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

— C

ollects 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.

10 Introduction

For example, a management console in the WMI application layer requests

the available free space on the client system hard drive. The WMI application

layer makes the request over the network to the CIMOM (in the Dell WMI

provider layer) on the client system. The CIMOM routes the request to the

appropriate WMI provider, which, in turn, routes the request through the

data router layer to the disk data provider in the data provider layer. The

information is then returned (through the same path in reverse) to the

management console.

NOTE: OMCI 7.6 and later versions will not be supported by Dell OpenManage

IT Assistant (ITA) 8.x.
