DSView software client
The DSView software client is a customer provided PC with an installed web browser.
The web browser accesses the DSView server and provides the user interface (that is,
the DSView Explorer) for the DSView software system. The DSView Explorer enables
users to access and administer the server, managed appliances and target devices.
DSView software client session
The DSView software client session is a single HTML session between the client web
browser and the server. For each DSView software client session, the user must log
into the DSView server. Multiple DSView software client sessions can exist between a
given DSView software client PC and the DSView server. This occurs when the user
launches another web browser window and connects to the same DSView server.
A DSView software client session may contain multiple target device sessions.
DSView software hub server
A DSView software hub server is responsible for maintaining the master copy of the
DSView software system database. Only one server in a DSView software system can
be configured as the hub server. Spoke servers in a DSView software system perform
database replication with the hub server. The DSView software hub server acts as the
traffic cop for database replication between itself and all of the other servers in a
DSView software system.
The DSView software hub server and a spoke server offer the same software
functionality to a user. The distinction of hub or spoke only has to do with the
database replication role the server plays and not with the software functionality the
server offers to the user.
The DSView management software versions of the spoke server and hub server must
match in order to register the spoke server. For example, you may not register a spoke
server running DSView version 3.1 with a hub server running DSView software
version 3.2.
DSView software spoke server
A DSView software spoke server is responsible for initiating database replication with
the hub server. A spoke server sends its database changes to the hub server and
receives database changes from it.
The DSView software hub server and a spoke server offer the same software
functionality to a user. The distinction of hub or spoke only has to do with the
database replication role the server plays and not with the software functionality the
server offers to the user.
