In cases where the requested bandwidth settings you specified for the four FlexNICs in a single physical port exceed 10Gb, the following rules are applied in this order:

1.

If FlexNICs with a "preferred" or "custom" value for requested bandwidth exceed 10Gb, each FlexNIC

 

is allocated bandwidth proportional to its requested bandwidth setting. For example, if four FlexNICs

 

on a given port have requested bandwidth settings of 1Gb, 2Gb, 4Gb, and 5Gb, their allocated

 

bandwidth is as shown in the table below. In this example, 200Mb remains after dividing the 10Gb

 

link. 100Mb is added to the two connections with the least bandwidth.

2.

Every FlexNIC that is linked must be allocated at least 100Mb. For example, if four FlexNICs on a given

 

port have requested bandwidth settings of 2Gb, 8Gb, Auto, and Auto, their allocated bandwidth is as

 

shown in the table below. In this example, 100Mb must be allocated to the two FlexNICs set to "Auto"

 

because no bandwidth would remain after allocating 2Gb and 8Gb to the first two FlexNICs. The two

 

FlexNICs set for 2Gb and 8Gb requested bandwidth are allocated a proportion of the 9800Mb

 

remaining after the two FlexNICs set to "Auto" receive 100Mb. In this example, there is a remainder of

 

100Mb, and that remainder is assigned to the FlexNIC whose allocated bandwidth differs the most

 

from its requested bandwidth.

For FlexFabric configurations, the allocated bandwidth for the assigned FCoE connections takes precedence over the Enet connections in all cases. This implies that if you add FCoE connection bandwidth to a server port that has both Enet and FCoE connections on different PFs, the Enet connection has less bandwidth according to the rules stated above.
