2.3 Client-Server Structure in a Network Environment
(Windows Environment)
It is possible to have several ACI-FDX cards in one computer, but it is also possible to have the
cards distributed to several computers in a Network. A sample configuration is shown in Figure
2.3-1.
Each computer, which has ACI-FDX hardware installed acts as
Server
. The server
computer provides board functionality to the connected clients. To access the hardware
from a client it is necessary to run the AIM Network Server (ANS) on the Server computer.
The computer which contains the application software acts as
Client
. A client does not
require ACI-FDX hardware.
However, ACI-FDX hardware can be installed on the computer which contains the
application software (a Client). In this configuration, local access from the application to
the hardware is provided. Therefore, it is not necessary to run the ANS.
