LAN Subsystem Management

HP NonStop IPX/SPX, the SLSA subsystem, and the PAM subsystem support DSM

and the Event Management Service (EMS). You can use the Subsystem Control

Facility (SCF) to manage these products interactively. The PAM subsystem also

provides the Subsystem Programmatic Interface (SPI) for writing management

applications.

LAN Application Example

Figure 9-3 is an application example that shows a large aerospace manufacturer using

PCs as cell controllers in a factory environment. The PCs send instructions to

programmable controllers and machine tools that assemble printed circuit boards

(PCBs).

The HP NonStop S-series servers communicate with the PCs across an Ethernet LAN.

They also communicate information collected from the PCs to various host computers

in the company.
