VACP-DCD Conceptual, Logical, and Physical Examples

Hello all,

Currently studying for my VCAP-DCD which I will write at VMworld this year.  I was wondering if anyone has any really good examples of the layout for:

-  Conceptual Design

-  Logical Design

-  Physical Design

I have done these before but I wanted to find some examples to make sure i'm getting everything correct or doing the desing as VMware wants to see them per say.

Any help is greatly appricated,

No one has any good references for these?

The design book by Scott Lowe has many examples of this as does his pluralsight course. Have a look at Duncan Eppings Cloud reference architecture pdf also for exmaples

http://www.vmware.com/files/pdf/techpaper/cloud-infrastructure-achitecture-case-study.pdf

If you attend the design course you will also learn about all of these.

There is also a book coming out very soon by VCDX001 John Arrasjid that is covering The Art of IT Infrastructure Design.

Thanks for the response.  Yeah I came across this document the other day as well and find it does a good job.  Thanks, I just wanted a nice clear understanding of what VMware views these models as.

The material available for the VCAP-DCD is too general IMHO, and nothing to specific.  I guess, this is a design exam after all and each design will have different requirements. The vcap-dcd based 5.5 was just released but looks a bit more organised the previous version, if you are going to attempt DCD, I would suggest give the 5.5 version a go, the blueprints are almost also same.

But anyway, here is nice document for Conceptual, Logical and Physical https://communities.vmware.com/servlet/JiveServlet/previewBody/17408-102-1-22493/Conceptual_Logical_...

Thanks vfk,


Yeah I've read over that document 2-3 times now but still find it to be a really bad example as like you said its very generic.  It also ports over to IT examples very poorly as a use case.  I'm currently working on putting something else together and will post it on the documentation section in the community I guess since I don't have a blog once i'm finished it.


It will essentially lay out the three catagories as such:

Create a conceptual Design

-  Create a conceptual design based on business requirements

-  Identify and categorize buisness requiremetns

-  Determine capacity requiremetns for a conceptual design

-  Determine availability requirements for a conceptual design

-  Determine security and compliance requirments for a conceptual design

-  Create a service definition for a conceptual design

This almost looks like a contents page of a paper listing the Buisness Requirements, Capacity requirements, ect, ect with a very simplisitc diagram if any diagram at all.  This is the framework for which you will build out your logical/physical.  Another way to look at it is your listing out what you are going to create in the logical design section.

Creat a logical Design

-  Not picking a specific vendor or model or software version, no config details, this shows how the structure will look.

Two examples of this would be:

LogicalNetwork.PNGLogicalStroage.PNG

These images are cropted out of other study materials and are not my creations so if they need to be removed please let me know and I'll create some fresh ones, just using them as an example.

Here we would create logical diagrams to show what we outlined in our conceptual design.

Physical Design

-  What is the hardawre vendor, storage, networking device that will be used.  How we will do the settings.

So this is where we would do another diagram but have IP's, Networks, Settings, ect.  The fine details that a installer would usally fill out or be putting in ect.

Example Diagram, again not my own and I can remove if its violating anything

PhysicalStorage.PNG

Again following that conceptual design we started with to finish off everything and tie off any loose ends.

If anyone has anything else to input while I'm creating this let me know and I will add it.  I just found this is such an open ended area / discussion topic that everyone kind of had there own way of doing it even though the construct is the same everytime.  I just wanted more VMware focused examples to help people put it together if they are new to the topics.  Or maybe my mind just works differently, so for those who falls in same crazy corner my mind falls in, hopefully this will help :smileysilly:

Nice work, looking forward to it, also although not entirely related I would like to some VM design and management pod design, Smiley Happy, hey if you are going all out, might as well go the whole 9 yard.


PS: It is about time you got a blog and download/upload your thoughts.

Are you taking 5.5 DCD?

No I'm taking the 5.1 DCD exam.  I passed the DCA 5.1 so i'm just keeping everything on the same track.  However I hear the 5.5 DCD exam is better then the 5.1 one is Smiley Sad  Not sure if you have can 5.1 DCA and 5.5DCD and still qualify for the DCX that way?

I think you can, they are still in the same major version of the exam, according to the certification page: Two Available VCAP5-DCD Exams

Passing either of these exams will earn VCAP5-DCD certification if you have also met the pre-requisites.

Looking the blueprint for DCD-5.5, the 5.5 exam looks like the better exam, and more streamlined.
