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.

FlexNIC a
2Gb (2/10)*9800Mb = 1900Mb 2000Mb
FlexNIC b
8Gb (8/10)*9800Mb = 7800Mb 7800Mb
FlexNIC c

FlexNIC d

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.
Managing MAC, WWN, and server virtual ID
settings
Use the following screens to manage MAC, WWN, and server virtual ID settings:
• Ethernet Settings (MAC Addresses) screen (on page 147)
o Select MAC addresses for server profiles
• Fibre Channel Settings (WWN Settings) screen (on page 149)
o Select WWN ranges for server profiles
• Serial Number Settings screen (on page 150)
o Add a serial number and UUID to server profiles
Ethernet Settings (MAC Addresses) screen
To access this screen, click the Network Settings (MACs) link in the left navigation tree, or click Network
Settings in the Network section of the home page.
This screen lists the MAC Address type and range that is used when creating server profiles.
The Type field identifies what MAC addresses are assigned to the server blades deployed within the Virtual
Connect environment. HP provides a number of pre-defined MAC address ranges, or you can choose to
