D.3 IRIS/TDWR Hardware Configuration
Example
Vaisala supports single and dual–redundant hardware configurations. Because of the
network communications features in IRIS there are many possible hardware configurations
that allow dierent tasks to be performed by various workstations.
The following example for a non-redundant system.

With the IRIS architecture, the RPG and MDT functions could be combined into the RDA
workstation. Reducing the amount of hardware increases the system reliability and reduces
maintenance. The RDA workstation also has all the features of an SD.
For redundant systems, there are two RDA's and two RPG's. The RDA's have dual network
interfaces and the active one outputs base data to both RPG's. This means that all the
products are made twice. Each SD is configured with 3 network interfaces, one for each RPG
and a separate one for network output to the SD's. Each SD is equipped with 2 network
interfaces, one for each RPG. Thus each SD receives 2 versions of each product, one from
each SD. If one RPG or network fails, the SD's continue to receive products from the other
one.
