How to implement a CMDB

By lmanas ·
I have read a lot of documentation about general aspects of the CMDB implementation but there's no specific information or any guide about the CMDB structure.
I have the ITIL foundations certificate, I read almost everything about the CMDB, I know the philosophy and it's very interesting. But...
Has anybody a CMDB implemented? What software do you use? How is the general structure?
Thanks
Laura

How to implement a CMDB - it's not as easy as you think

by r.hamilton.pa In reply to How to implement a CMDB

Support tools, such as Remedy, now have a CMDB as part of their offering. Don't have a software solution like Remedy, then remember that a CMDB can be one database, two databases that are linked, an Excel spreadsheet, etc. Think about what a CMDB is according to ITIL.

Configuration Management provides the foundation for successful IT Service Management and underpins every other process. The fundamental deliverable is the Configuration Management Database (CMDB), comprising one or more integrated databases detailing all of the organization?s IT infrastructure components and other important associated assets. It is these assets that deliver IT services and they are known as Configuration Items (CIs). What sets a CMDB apart from an ordinary asset register are the relationships, or links, that define how each CI is interconnected and interdependent with its neighbors. These relationships allow activities such as impact analysis and ?what if?? scenarios to be carried out. Ideally the CMDB also contains details of any incidents, problems, known errors, and changes associated with each CI.

The tools are flexible. It's applicable to large teams as well as small. However, companies shouldn't merely consider their size when hunting for Configuration Management tools. They must consider the complexity of their IT infrastructure problems. The question is not a test of how big the shop is but how complex the management problem is. After all, companies can find themselves needing to grow or expand a unit rapidly. You need a tool that will meet your needs today but that will let you grow as well.

We are in the process of implementing BMC's Remedy.

Get to know your data center with CMDB
By Brian Kraemer, Assistant Editor
05 Apr 2006 | SearchDataCenter.com

IT analyst firm Forrester Reseearch, Inc. recently evaluated the strengths and weaknesses of vendors that have brought dependency mapping and CMDB tools to market. According to Forrester, all products performed strongly, but it favored products from San Jose, Calif.-based nLayers Inc. and Relicore Inc. [recently purchased by Symantec Corp.]. Forrester also liked BMC Software Inc., Tideway Systems Inc. and Collation [recently purchased by IBM]. Mountain View, Calif.-based Mercury and Cendura were also listed as contenders. CA, Inc. and Hewlett-Packard Co. are relatively new to the market, but Forrester expects them both to be heavyweight entrants.

Devil is in the detail

by GlennHughes In reply to How to implement a CMDB - ...

I can empathise with your predicament.

My organisation is in the middle of implementing HP OV apps including service desk, OVO and Radia. Quite a tall order and includes SD CMDB and Radia CMDB (they both have their own!). We've done all the design work and now we're down into data. In our org we have multiple in house and externally supplied systems holding CI data we want plus Access and Excel based databases. Some of our main issues are now around organisational/political areas such as who actually owns the data now and in the future under ITIL, Who's going to clean it, maintain it and what exactly are the relationships between CI's (as Rich mentioned, a key benefit)?

Our CMDB arose out of our adoption of ITIL but now it is gaining a profile in it's own right (analysts are saying it is overtaking ITIL as a topic in N America).

We're not there yet but my advice is start simple and work your way up and also produce CMDB requirement specs which helps you focus on exactly what you want. At the end of the day it needs to support your ITIL processes (assuming you are not implementing a CMDB in isolation!).

Very carefully

by twohills In reply to How to implement a CMDB

Start with what you have to get out and work backwards: what reports or queries do you need to support? </br></br>
Be brutally pragmatic: note I said "have to" and "need'. CMDB projects are no place for nice-to-haves and idealism. Scope can rapidly balloon out to be unachievable: see <a href="http://www.itskeptic.org/taxonomy/term/6?">the IT Skeptic</a> who contends that the ideal CMDB is practically impossible. </br>
</br>

And if you don't know the answer to "what reports or queries do you need to support?" then you don't need a CMDB. The surveys I have seen on how many organisations have impemented CMDB are in the 10-15% range, i.e. the majority of organisations do business without one.

I Struggled at first

by IIkoti In reply to How to implement a CMDB

Then I bumped into this dude from a start up company that had a pretty cool CMDB although he didn't realise that's what it was, have been trialing it for them for a few weeks now. Managed to get them to give it me for free as I was one of the first to take it up:) From a company called ephortechnologies.com Haven't got his contact details on the site though so you may have to do some digging.
