User guide

Users may connect to the DSView 3 server from DSView 3 software clients and use the
DSView 3 Explorer windows to communicate with the system.
DSView 3 server
The DSView 3 server contains the DSView 3 management software. The server provides a
centralized database for storing configuration, user, unit and system information. It also
provides services for authentication, access control, logging events, monitoring and license
management.
You may configure one or more spoke (backup) servers in addition to the hub server. The hub
server is responsible for maintaining the master copy of the database in a DSView 3 software
system. Only one server in a DSView 3 software system may be configured as the hub server.
Spoke servers perform database replication with the hub server. The hub server acts as the
coordinator for database replication between itself and all of the other spoke servers in a
DSView 3 software system. A hub server and a spoke server both offer the same DSView 3
software functionality to a user. The distinction of hub or spoke refers only to the database
replication role that the server plays and not with the functionality that the server provides.
Adding one or more spoke servers to a DSView 3 software system provides redundancy and the
ability to distribute DSView 3 software functionality across multiple sites.
After the hub server and optional spoke server(s) are configured, you may create and configure
the type of access levels for users within your network environment. You may also set up event
logs to record full details of user access and other events.
DSView 3 software client
A DSView 3 software client is a computer with a web browser that can access the DSView 3
management software installed on the DSView 3 server.
Third party products
Third party products are not a part of the DSView 3 software, but are supported for use with it.
External authentication servers - An external authentication server enables the DSView 3
server to broker authentication requests from users requesting access to the DSView 3 software
system.
SNMP managers - The SNMP (Simple Network Management Protocol) manager monitors the
managed appliances and receives SNMP traps from the DSView 3 software on the server. An
example of an SNMP manager is the HP OpenView product.
Third party Telnet viewers - A third party Telnet viewer may be used for serial sessions instead
of the DSView 3 software Telnet Viewer.
