Active Connections
Active connections describe the connections that a client makes to a server. Passive
connections describe the connections that a server allows the client to complete.
The maximum number of active connections per port for an adapter are required when
setting the “ConnectionCountPerRdmaNetworkInterface” parameter. Use Table 3-5 to
determine the correct number of maximum active connections based on your
OCe14000-series adapter and operating system.
Note: Passive and active connection limits for both the OCe14000-series adapters are:

Active mode — See Table 3-5 below.

Passive mode — Maximum passive connections are calculated using the
following equation:

511 - (2 * number of ports)

Passive + Active mode — Active and passive connection counts together
should not exceed 511 - (2 * number of ports) as calculated above.
