User's Manual
Spoke servers are primarily used for redundancy of all PDU management and to have improved
scalability. They 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 Rack
Power Manager software system. A hub server and a spoke server both offer the same Rack
Power Manager 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 Rack Power Manager software system provides
redundancy and the ability to distribute Rack Power Manager software functionality across
multiple sites. Power consumption data is not replicated to all spokes, however, when a report
is created it spans across all servers to gather the data.
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.
Rack Power Manager software client
A Rack Power Manager software client is a computer with a web browser that can access the
Rack Power Manager management software installed on the Rack Power Manager server.
Third party products
Third party products are not a part of the Rack Power Manager software, but are supported for
use with it.
• External authentication servers - An external authentication server enables the Rack Power
Manager server to broker authentication requests from users requesting access to the Rack
Power Manager software system.
• SNMP managers - The SNMP (Simple Network Management Protocol) manager monitors
the managed appliances and receives SNMP traps from the Rack Power Manager 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 Rack Power Manager software Telnet Viewer.
Supported Units
For management functions, the Rack Power Manager software client uses HTTPS (Hypertext
Transfer Protocol with SSL encryption) to send a request to the Rack Power Manager server,
which then sends a command to the managed appliance. The appliance then performs the
requested function.
