AWAN Access Server and SWAN Concentrator
Comparison
AWAN Access Server and SWAN Concentrator
Comparison
This subsection compares the AWAN access server and the ServerNet wide area network
(SWAN) concentrator. The SWAN concentrator is a LAN-based communications device
that can provide asynchronous terminal and serial printer connections for Himalaya S-
series servers. The SWAN concentrator uses the ATP6100 subsystem on the Himalaya
NonStop server to provide these types of connections.
