(number of Ethernet switches)
Number of client access network IP addresses =
(number of database servers)*2 + 3
Number of InfiniBand network IP addresses =
(number of database servers)*2 + \
(number of storage servers)*2
Number of additional network IP addresses =
(number of database servers) * (number of additional networks)
