project management white papers IT Service Management: Setting up the right Configuration Management Database(CMDB)

1. introduction

 

This white paper examines a significance of a good determined as well as confirmed CMDB for improved carry out of changes to CIs (configuration items).

Audience

 

This white paper serves as a starting indicate for infrastructure as well as ITSM routine as well as pick up consultants concerned in defining as well as substantiating a CMDB to await operate design, passing from a single to another as well as operation processes.

2. What is CMDB?

 

Configuration Management Database (CMDB) is a judicious storage of report of all Configuration Items (CIs), such as applications, servers, networks, hardware as well as documentation. A CMDB captures assorted attributes of CIs as well as preserves their updated, i.e. either a CI is in development, tested, prolongation or archived, to illustrate enabling improved shift control.

 

3. because is cmdb important?

 

CMDB is accessed by all Service Management (ITSM) processes for CI report as well as as a result it is critical to set up as well as say a right turn of CMDB for following reasons:

 

Ability to uncover finish operate infrastructure upon a single page

 

To brand any sort of CI, combining a service

 

Support relations in between CIs

 

CIs impacted by each shift as well as recover

 

CIs influenced by incidents as well as problems

 

Better formulation of operate upgrades or improvements

 

Control of CIs as well as services

4.  steps to set up a cmdb

 

·         Identify a range of CMDB

Prepare a petition with questions especially focussing around:

Ø  IT services defined
Ø  Applications combining a partial of IT services
Ø  Critical applications in conditions of business
Ø  Priority of applications in conditions of SLA vulnerability
Ø  Software, Hardware as well as network components ancillary applications
Ø  Attributes or characteristics of CIs, such as name, type, id, version, status, permit detail, place etc

 

·         Identify a CIs Ø  Once a applications have been identified, collect a applicable CIs combining a partial of a application, to be entered in to a CMDB.
Ø  Categorise a CIs
Ø  Finalise a CI attributes as well as fixing convention
Ø  The applications establish a length whilst a CI sum establish a length of a CMDB

 

·         Populate a CMDB Ø  Enter CI sum manually or operate a apparatus such as Tivoli Discovery Manager to find CIs in IT infrastructure
Ø  Define CI relations e.g. Portal server(CI 1) is commissioned with server software(CI 2)
Ø  Label CIs, as per fixing convention, with a plaque or marker
Ø  Group associated CIs to form collections e.g. A pick up could contain an focus server, continuous networks as well as commissioned software

 

·         CMDB Control as well as Maintenance Ø  Define CI lifecycles for varying CI sorts e.g. A CI with sort 'software’ could have a lifecycle with a following standing transitions: development-test-build-production-decommissioned
Ø  Update a standing of CIs depending upon a shift ask e.g. CI statues could be development, test, build, production, decommissioned
Ø  Update attributes of all associated CIs
Ø  Inform applicable stakeholders about CI updates by equates to of continual reports

 

·         CMDB Verification as well as Audit Ø  Define CI lifecycles for varying CI sorts e.g. A CI with sort 'software’ could have a lifecycle with a following standing transitions: development-test-build-production-decommissioned
Ø  Update a standing of CIs depending upon a shift ask e.g. CI statues could be development, test, build, production, decommissioned
Ø  Update attributes of all associated CIs
Ø  Inform applicable stakeholders about CI updates by equates to of continual reports

 

 

 
 
 

  5. conclusion

 

An integrated CMDB provides a complete, downright design of all related Configuration Items combining services. This enables simpler marker of CIs impacted due to incidents as well as improved carry out of changes to CIs in conclusion heading to improved operate operation as well as operate delivery.
