Introduction 7 Introduction The Dell™ OpenManage™ Client Instru mentation (OMCI) software enables r emote management application programs to access client system information, monitor the client system status, or chang e the state of the cl ient system; such as shutting it down r emotely . Through standar d interfaces, OMCI e xposes k ey system [...]

8 Introduction • The CIM data model abstracts and de scribes 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 F ormat (MOF) file, which provides a [...]

Introduction 9 OMCI uses a variety of data sources r esident on the client system which includes: • Microsoft W in32 WMI providers •S M B I O S • Device drivers • Operating system r egistry • Operating system Application P rogramming Interfaces (APIs) • WMI r epository OMCI Architecture The OMCI architecture is based on a layer ed model[...]

10 Introduction F or example, a management console in the WMI application layer requests the available free space on the client sy stem har d drive. The WMI application layer make s the r equest over the netwo rk to the CIMOM (in the Dell WMI provider layer) on the client system. The CIMOM routes the request to the appropriate WMI provider , which,[...]

Introduction 11 Features The following are k ey features of OMCI: • CIM 2.6 Schema Support • Dell LegacySelect 2.0 Support • Remote Boot Device Select • WMI Security • Event Reporting • Remote Shutdown • Remote W ak e-Up Configurability • WfM V ersion 2.0 Compliance CIM 2.6 Schema Support CIM is a standard that describes management [...]

12 Introduction A network administrator can change the settings of these components either through the computer's system setup or by using a WMI management application. NOTICE: Changing LegacySelect attributes such as Integrated Drive Electronics (IDE) Controller may cause a computer sy stem to become unusable. If this occurs, enter sy stem se[...]

Introduction 13 processes that may be running. If the temperatur e increases too quickly and OMCI does not poll the system in ti me, it will not generate a shutdown message and the system will not shut down cleanly . OMCI also contains a start delay for the polling intervals. This determines how l o n g a ft e r t he op er a ti ng sy st em loads, O[...]

14 Introduction • Additional Display Device Information: Earlier OMCI r eleases provided limited display device informati on. OMCI 7.6 also provides the manufactur e date in <yyyy W eek ww > format; y-year , w-week number (for example, 2008 W eek 16) and the po ssible sleep states of the monitor . • Additional Physical Memory Information:[...]
