Why CIM? CIM in Grid Standards

Whats the Problem with Management Data?
Not all data is created equalCheck boxes that indicate management data provided areNOT enough
Each technology (and sometimes each productoffering) represents its management data in adifferent way
Creating its own semantics, terminology, data structures andprotocols
Management is NOT the area for differentiation butfor conformance
Uniqueness costs the customers in design time,normalization,

Whats the Problem When Managing Resources?
Although they are easier to define
Or new technologies
XML, YML, ZML
All of these convey how to communicate butnothing about the data
What is communicated?
How is the data analyzed/used?

What Do End Users and Businesses CareAbout?
555 2003, Cisco Systems, Inc. All rights reserved.
End to End Management
Sharing information andaccess to data
Data retention andavailability
Communication /transmittal of information
Processing of necessarytasks
666 2003, Cisco Systems, Inc. All rights reserved.
End User Distributed processes, policies anddata
Data to be retained and retrieved as quickly as possible
Vendors Lots of individual productsSoftware Application and services (for ex, database,storage, tape backup, security, )
Hardware Computer, networking,
Each vendor knows their product, not their placein the bigger picture
The end user needs to know each product, ANDthat products place in supporting the business

An Ideal World
Complete description of the managedenvironment
Scalable from the big picture
Going to the component level only when necessary
Emphasis on applying interoperableknowledge to the managed environment
Requires:Common information model to describe and organizethe managed environment
Policies to manage the system (May or may not beautomated)

Whats a Solution?
Work toward documented common concepts andcommon model (-> CIM)
ComputerSystem, StorageVolume, ProtocolEndpoint,Collection,
This is possible - In most parts of the world, Where isthe bathroom? is understood
Goal to have one size fits all - a basicdictionary for management
Define documented translations into othermodels and languages
Support for different environments and languages,such as WSDL

But Is Information Modeling Possible?
The Semantic Web, Scientific American, May2001 (Berners-Lee, Hendler and Lassila)
Human language thrives when using the sameterm to mean somewhat different things, butautomation does not.
Clowns, business addresses and PO Boxes
Human endeavor is caught in an eternal tensionbetween the effectiveness of small groups actingindependently and the need to mesh with thewider community. A small group produces asubculture whose concepts are not understoodby others. Coordinating actions across a largegroup, however, is painfully slow and takes anenormous amount of communication.

How Does CIM Complement GGF OGSA?
Description of relationships (dependencies,component structures, etc.)
Management and modeling of resources
End to end context for management data
Management of the OGSA architected servicesFunctional vs management interfaces
Automated mapping from model definition toXML Schema/WSDL/WS-RF/

Example of CIMs Use CIM-SAN/SMI-LabDemos
October 2002, April 2003 and October 2003
17 vendors integrated 32 products creating 97 points ofinteroperability
Physical inventory information (disk drives, cache, front andback end ports) for disk arrays
Added logical inventory (LUNs and other storageinformation) and extended the modeling to cover otherdevice types such as tape libraries, NAS systems and FCswitches
22 participating companies integrating 40 products andcreating more than 300 points of interoperability
Added key functionality like: Volume management andconfiguration reporting
