Expand Subsystem and the NonStop Operating
System
Multi-Node Process Communications
Figure 2-2 illustrates the same file-system request as Figure 2-1 on page 2-3, except
that the disk process resides on another node in the network rather than on another
processor in the same server.
Multi-node process communications is the same as single-server process
communications, with these exceptions:
•
The Expand subsystem redirects the file-system request to a hardware
communications device.
•
A communications line rather than the ServerNet SAN carries the message to the
remote process.
