Expand / Diagram                                               see System Quirks

 

 

The Expand / Diagram screen provides a pictorial view of the Expand network.

 

Expand is the name of the subsystem and system software that provides transparent communication between two or more Tandem systems.

 

When first started, the nodes or systems on the network are placed right next to each other.  Place the mouse within the system box in the 'unused' area and press and hold the mouse to drag the Systems to desired locations.  Press the Save Config All button to store the screen layout (the locations are not automatically saved).  Placing the mouse over a connection line displays additional detail about the underlying paths and lines.

 

 

 

The boxes representing each System on the network may be configured by right-clicking over the image in the center of the box.  Various visual attributes such as the system image and color of the box frame may be changed.  The box "Hide this System" is used to prevent display on this screen of undesired Systems in the network.  Systems are restored on the Expand / Connections screen.

 

 

 

 

Placing the mouse over a connection between two Systems and clicking will bring up a detailed diagram of the connections, states, frame rate and byte rate between the two nodes.  Frame rate and byte rate (if available) are also displayed for each line and a total for the path.

 

 

 

 

If a MOMI client connects to multiple systems, and the multiple systems are interconnected using different Expand networks, it is possible group them separately.  This differentiation is define within the CONFMOMI file using the keyword EXPAND-NETWORK-NAME.  Below is a diagram showing two networks.  The first network comprised of \BWS1 and \BWS2 is unnamed.  The second network is called ITUG2005.  Notice the network name appears in the box with each system.

 

 

 

To obtain the maximum amount of detail available, MOMI must be installed on all nodes.  Monitoring is activated for all nodes under the Systems / Basic tab.
