  1. Overview of DMTF, SMWG and CIM 2004 . 3 . 30 So Jung Lee DPNM Lab. POSTECH

  2. DMTF(Distributed Management Task Force)

  3. DMTF Overview • DMTF is the technology industry organization leading the development of management standards for distributed desktop, network and enterprise environments • Goals • Neutral forum • Promote interoperability • Move quickly in the new age • Raise the bar for management

  4. DMTF Organization • Founded in 1992 • Changed the group name in May, 1999 Desktop Management Task Force  Distributed Management Task Force • “Not for profit” corporation • Member companies • Board members : 3com, Cisco, Compaq, Dell, HP, IBM, Intel, Microsoft, NEC, Novell, Sun, Symantec • Customer Advisory Board is formed with 7 customer members

  5. DMTF Standards • Common Information Model (CIM) • Web Based Enterprise Management (WBEM) • Common Information Model (CIM) • xmlCIM : XML encodings for CIM • CIM Operations over HTTP • Directory Enabled Networks (DEN) • Desktop Management Interface (DMI) • Alert Standard Format (ASF) • System Management BIOS (SMIOS)

  6. SMWG(Server Management Working Group)

  7. SMWG Overview • Need of Standard Server Hardware Management Interfaces grows more and more. • Dell, HP, IBM and Intel Corporation has lead the formation of DMTF SMWG. • Include the key vendors such as AMD, Microsoft, Oracle, OSA Technologies and Sun Microsystems. • First face-to-face meeting was on 17-18th of December, 2003 • Goal • To develop Industry standard server hardware management architecture by evolving CIM • To develop CLI for managing server hardware • To advance CIM for recent server system technologies

  8. Management Problems • There is no uniform way of managing heterogeneous servers independent of machine state, operating system state, server system topology and access mechanism • There is a need to extend the CIM standard to cover various server system (ex. Blades and virtualized server system) • There is a need for lightweight command line interface that can be mapped to CIM

  9. WG Charter • The goal of SMWG is to define a platform independent, industry standard management architecture through the following technologies. • Extend CIM schema • Leverage the CIM/XML protocol and identify enhancements if necessary • Define CIM protocol • Define profiles for different server system topologies • Define an architecture model for understanding the semantic behavior of server management components • Demonstrate interoperability

  10. WG Charter - cont’d • The scope includes the following: • Wide range of Server profiles (ex. Stand alone, blades, racks..) • Enumeration of hardware and hardware related software • OS present/not present • Discovery, proxy, aggregation, redirection • Select, control and transfer executable images • Power control, system control, configuration and monitoring • OS recovery assistance • Boot process visibility • Basic alerts/events • Access to logs • View and set status indicators (LED, text LCD, alarms etc)

  11. Alliance Partnerships • OASIS • Web services Manageability, Web Services Technologies, Distributed Management Infrastructure • SNIA • Storage Management Initiative • W3C • Web Services architecture and technologies • SA Forum • Service Availability Forum

  12. Current work – Deliverables & Timeline • Phase 1 deliverable: July 1, 2004 In the CIM v2.9 Timeframe the SMWG will deliver • Lightweight command line interface specification • Lightweight CIMOM and supported CIM operations specification • Standard server system topology profiles • Phase 2 deliverable December 31, 2004 • Compliance specification • Test cases for interoperability • Interoperability testing

  13. CIM(Common Information Model)

  14. CIM Overview • Provides a common definition for management information for systems, networks, applications and services • Platform-independent and technology–neutral schema for describe, create and share all management object • Object-oriented model • CIM is a data model not an implementation • CIM provides models for both instrumentation and management • CIM is comprised of Specification and Schema • Schema provides actual model description • Specification defines the details for integration with other management models

  15. CIM Schema • Three layers of CIM Schema • The Core Schema • The essential set of managed objects that apply to all management areas • The Common Schema • The set of managed objects that are common to particular management areas • Networks, systems, applications, databases, the devices • Extensions to the schema • Specific extensions of the common schema

  16. The expression of CIM Schema • MOF (Managed Object Format) • ASCII text file • Contains the formal definition of the CIM schema • Input into and compiled by MOF compiler • VISIO-UML (Unified Modeling Language) • XML (eXtensible Markup Language) • XML grammar describes CIM metaschema detailed in DTD specifying tags such as CLASS, INSTANCE and QUALIFIER • Meta mapping

  17. MOF example [Association, Version ( "2.6.0" ), Description ( "The ActsAsSpare association indicates which elements can spare " "or replace the other aggregated elements. The fact that a " "spare can operate in \"hot standby\" mode is specified on an " "element by element basis.")] class CIM_ActsAsSpare { [Key, Description ("The SpareGroup.")] CIM_SpareGroup REF Group; [Key, Description ("A ManagedSystemElement acting as a spare and participating in theSpareGroup.")] CIM_ManagedSystemElement REF Spare; [Description ("HotStandby is a boolean indicating that the spare is operating as a hot standby.")] boolean HotStandby; };

  18. UML Example

  19. XML example <?xml version= "1.0"?> <!DOCTYPE CIM SYSTEM http://www.dmtf.org/cim-v2.dtd/> <CIM VERSION=“2.0”> <CLASS NAME=“ManagedSystemElement”> <QUALIFIER NAME= “abstract” TYPE=“boolean”> <VALUE>TRUE</VALUE> </QUALIFIER> <PROPERTY NAME=“Caption” TYPE=“string”> <QUALIFIER NAME=“MaxLen” TYPE=“sint32”> <VALUE>64</VALUE> </QUALIFIER> </PROPERTY> <PROPERTY NAME=“Description” TYPE=“string”> </PROPERTY> <PROPERTY NAME=“InstallDate”TYPE=“detetimev”> <QUALIFIER NAME=“MappingStrings” TYPE=“string”> <VALUE>MIF.DMTF|ComponentID|001.5</VALUE> </QUALIFIER> <PROPERTY> <PROPERTY NAME=“Status” TYPE=“string”> <QUALIFIER NAME=“Values” TYPE=“string” ARRAY=“TRUE”> <VALUE>OK</VALUE> <VALUE>ERROR</VALUE> <VALUE>Degraded</VALUE> <VALUE>Unknown</VALUE> </QUALIFIER> </PROPERTY> </CLASS> </CIM>

  20. Development Timeline • Started work on CIM in 1996 • CIM Specification v2.2 is current • CIM Schema released: • V1 released in 1997 • V2.0 and 2.1 in 1998 • V2.2 in June, 1999 • V2.3 in November, 1999 • V2.4 in June, 2000 • V2.5 February, 2001 • V2.8.1 is the last version

  21. Storage Related Changes • Over last three years much has been added to CIM for storage management • Storage devices (tape, disk) • Storage extents abstractions • Redundancy mappings • Automated library representations • SCSI, FC, connectivity • Associations for all above

  22. Support • The CIM Schema is in use in • SUN Solaris 8.0 • Sun Management Console • Windows 2000 • Computer Management Application • Add-in for Windows NT 4.0 • Similar functionality to W2K • SNIA Interoperability Demonstration • Many firms involved, including Troika, Seagate, Hitachi, STK, Compaq etc.
