HP Virtual Connect for c-Class BladeSystem Version 3.30 User Guide

Virtual Connect server profiles 128
100Mb, and that remainder is assigned to the FlexNIC whose allocated bandwidth differs the most
from its requested bandwidth.
Requested Calculation Allocation + remainder
FlexNIC a
2Gb (2/10)*9800Mb = 1900Mb 2000Mb
FlexNIC b
8Gb (8/10)*9800Mb = 7800Mb 7800Mb
FlexNIC c
Auto 100Mb 100Mb
FlexNIC d
Auto 100Mb 100Mb
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 128)
o Select MAC addresses for server profiles
• Fibre Channel Settings (WWN Settings) screen (on page 130)
o Select WWN ranges for server profiles
• Serial Number Settings screen (on page 131)
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
enter a range of locally-owned MAC addresses. HP does not recommend using the server factory default
because these addresses do not move when the server profile is assigned to a new physical server blade.
VCM assigns or migrates MAC addresses for server Ethernet ports connected to VC-Enet modules. VCM also
assigns MAC addresses to server Ethernet ports that are not connected to an I/O module because VC
modules can be added later. Server Ethernet ports connected to non-VC modules retain the server factory
default MACs addresses. Only ports that have connections assigned in the server profile are assigned MAC
addresses. Any unassigned ports, which includes Flex-10 connections, retain their factory default MAC
addresses.
When using HP pre-defined or user-defined MAC address ranges, only use each range once within the same
layer 2 network to avoid multiple servers having the same MAC addresses. After MAC addresses have been
assigned as part of creating a server profile, this setting cannot be changed.
