NBU Shared Storage Guide  http://www.symantec.com/docs/DOC3659

See Section 2: OpenStorage option

p.58:
The disk appliance is the storage server.

A storage server is a 'virtual' entity in NBU that certain storage types are configured on, eg. Advanced Disk or Pure Disk

PLEASE read through the section of the manual that I have referenced above.
TRUST me, all bits and pieces will make sense once you have gone though that section. There are even diagrams/pictures that make it all easy to understand.
This is how we all learned...

It is simple a 'virtual' entity that manages disk storage (apart from basic disk).

From the Admin Guide.

Storage Server

 

An entity that writes data to and reads data from the disk storage. A storage
server is the entity that has a mount on the file system on the storage.
Depending on the NetBackup option, the storage server is one of the following:
■ A host that is part of a storage appliance or filer
■ A NetBackup media server
■ For Nirvanix cloud storage, nirvanix.com.
■ Disk pool

How storage server manages the disk storage?

mph999's picture

Many processes are used to allow the storage server to manage disk, these are the main ones

nbrmms is the process that runs on the media server to manage disk storage.

 

Remote Manager and Monitor Service (nbrmms) is the conduit
through which EMM discovers and configures storage on media
servers. In addition to configuration management, nbrmms
provides all access to media server resources for monitoring and
event notifications.

dps - disk polling service

rdsm

 

The Remote Disk Service Manager interface (RDSM) runs within the
Remote Manager and Monitor Service. RDMS runs on media servers.
 
stssvc - The Storage Service manages the storage server and runs on the media
server.

NIKHIL, you have marked this thread as SOLVED on 24 May.

By doing that, you indicate that your question has been ANSWERED!

Martin has explained all the NBU processes in his excellent post.

If you need to know what happens on the Storage Server (Data Domain), please have another look at my comment in your other 'data domain' post: https://www-secure.symantec.com/connect/forums/dat...

How the Storage Server (Data Domain) manages these folders is a discussion you need to have with your DD support team.
They normally provide training and documentation specific to DD management.

@Martin: wana know what exactly  happens on the Storage Server (Data Domain),

mph999's picture

Sorry Nikhail, I didn't see your reply ...

What do you mean to ask  ....

At the most basic the Datadomain is just a disk - nothing happens on it, it just holds data.

You couold set up advanced disk on your server, for example, on my test server I have /sp3 filesystem which I have configured as advanced disk.  /sp3 is on one of the internal drives.

A datadomain device, is just a very expensive version of this ...

BUT...

Datadomains are a bit clever - for example ....

I could send my data to my datadomain disk, and, the datadomian will dedup the data ... this is done outside of netbackup, and netbackup knows nothing about the dedup, as it is all done by the dd device.
