Client/Server Processing
For G-series systems, the ServerNet SAN provides the communication path used for
interprocessor messages and for communications between processors and I/O
controllers. Refer to the ServerNet Communications and Configuration Manual for a
detailed description of the ServerNet SAN.
The SWAN subsystem is a collection of software and hardware components that
provides G-series systems with networking and data-communications capabilities. The
SWAN subsystem is used to configure both WAN and LAN connectivity for these
supported communication (COMM) subsystem objects:
•
ATP6100 line-handler processes
•
CP6100 line-handler processes
•
EnvoyACP/XF line-handler processes
•
Expand network control process, line-handler processes, and line-handler devices
(Expand LINE and PATH objects)
•
SNAX/APN service manager processes and line-handler processes
•
SNAX/XF service manager processes and line-handler processes
•
X25AM line-handler processes
For further information about the SWAN subsystem, refer to the ServerNet
Communications Configuration and Management Manual.
