To answer your question in basic terms:   Networker has 3 layers..

Networker Server
Networker Storage Node (dedicated storage node)
Networker Client

A Networker Client is a system that backs up using Networker, but does
NOT have or Use any Locally Attached Tape (backup) devices.

A Networker Storage Node "SN" is a system that backs up using Networker,
but has the ability to backup using locally attached Tape (backup)
devices. It is also licensed to be able to backup data from "Networker
Clients".

A Dedicated" Storage Node "DSN" is the same as a "Networker storage
node", but the license only allows it to backup data from itself, no
other client can use this as its Storage Node

A Networker server can backup Data in the same fashion as a "Storage
node"


Simply:  if a system has no backup devices attached locally, networker
client, if it has locally attached backup devices, and licensed to use
them, then its an "SN"/"DSN"

Subject: [Networker] Storage Node Explanation

I want to make sure I understand what a Storage Node does 

I have 3 remote locations connected to corporate that I would like to
backup with Networker. My Networker server is at the corporate location.
If I understand this correctly I can place a tape drive attached to a
server at each location and configure a storage node on my Networker
server for these locations. The Networker server controls the backups at
the remote sites, backing data to the tapes at those sites and sending
index information back to the main server at corporate. Is this correct?
