We have told you before: Do not confuse MSDP (Media Server dedupe) with your Data Domain.

Need I give you URLs where we told you this?

PS: 
Neither MSDP nor Data Domain are NetBackup Appliances (where you have posted this thread).
Explained over here: https://www-secure.symantec.com/connect/forums/nbu-appliances-1

I have never seen the term CSDP other than used by you: https://www-secure.symantec.com/connect/forums/what-basic-use-data-domain#comment-6764321

MSDP or PureDisk  is the same thing?

I was saying to you that you have posted in the wrong forum. 

This forum is for NBU appliances ( http://www.symantec.com/backup-appliance )

If you have general dedupe questions (such as MSDP or 3rd party dedupe appliance), you should post in NetBackup forum.
