High reliability configuration

The high reliability configuration option builds on the standard reliability option. The high reliability option duplicates components, so that no single point of failure exists in the control network. The high reliability configuration consists of the following components:

Two S8700-series Servers

Two IPSI circuit packs in each IPSI-connected port network

Two Ethernet switches

Two UPS units

Circuit-switched traffic between port networks is carried on a simplex network that is made up of one Expansion Interface (EI) in each port network. The EIs are cabled with lightguide fiber to either the Center Stage Switch (CSS) or an Asynchronous Transfer Mode (ATM) switch.

Figure 29: S8700-seriesfiber-PNC in a high reliability configuration on page 95 shows an example of a high reliability configuration.
