The Common Information Model The Common Information Model (CIM) Is Developed by the Distributed Management Task Force (DMTF) –Hewlett Packard –Cisco –Sun Microsystems –Intel –EMC –Many others

The Common Information Model CIM Is An Industry Standard Created To Abstract Proprietary Technology Away From the System Administrator –Heterogeneous Resources Controlled By A Common Interface –Solves The System Administrator’s Problem

System Administrators Problem Administrator Access System 1: Windows System 3: Solaris System 2: Linux

The Common Information Model CIM Schema Is Broken Into 3 Layers –Core Model - Generic Representations Of Managed Objects Systems, Network Components, Services, Devices –Common Model - Specific Managed Objects Computers, Networks, Applications –Extension Schemas - Technology Specific Extensions of the Common Model UNIX, Microsoft Windows
