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?

Not about:Protocols

Although they are easier to define

Or new technologies

XML, YML, ZML

Or interfaces/APIs

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?

End to End Management

Sharing information andaccess to data

Data retention andavailability

Communication /transmittal of information

Processing of necessarytasks

Differing Perspectives

End User Distributed processes, policies anddata

Security concerns

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

Standardized semantics

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/
