High-Reliability Configuration
The high-reliability configuration shown in
servers, duplicated control networks, and duplicated IPSIs in the IPSI-connected
EPNs. With this configuration, every IPSI-connected EPN must have duplicated
IPSIs. The duplicated control network prevents a single fault in the control
network, such as a bad Ethernet switch, from bringing the whole system down.
Since the IPSI’s are duplicated in this configuration, the PKT-INT circuits are also
duplicated.
