DSView software server
The DSView software server contains the DSView management software that enables users to
securely access, manage, monitor and control remote target devices through managed appliances.
The DSView software server provides a centralized database repository for storing configuration
and user, unit and system information. The software server 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
software system. Only one server in a DSView 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
software system. A hub server and a spoke server both offer the same DSView management
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 software system provides redundancy and the ability to
distribute DSView software functionality across multiple sites. For more information about
replication, see Replication on page 77.
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 software client
A DSView software client is a computer with a web browser that may access the DSView
management software installed on the DSView software server. A user may access and administer
the DSView software server and units using the DSView software client.
Third party products
Third party products are not a part of the DSView software, but are supported for use with it.
External authentication servers - An external authentication server enables the DSView software
server to broker authentication requests from users requesting access to the DSView
software system.
SNMP managers - The SNMP (Simple Network Management Protocol) manager monitors the
managed appliances and receives SNMP traps from the DSView 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 software Telnet Viewer.
