VC-assigned or server factory default MAC addresses may be used for FlexNICs. When using server factory default MAC addresses, FlexNICs will still have unique MAC addresses. For example, the BL495 BladeSystem server has 8 factory-assigned MAC addresses. Each FlexNIC on a physical port can be assigned to a different vNet or remain unassigned, but multiple FlexNICs on a single port cannot be assigned to the same vNet. This is an architectural limitation and will not change. Both of these situations are displayed in Figure 10. In the scenario on the right, if additional bandwidth is required, the administrator can reduce bandwidth on an underutilized FlexNIC and allocate that bandwidth to the FlexNIC that requests it.

Existing (pre-Flex-10) server profiles may be assigned to Flex-10 ports. The connection port speed will default to Auto. Flex-10 allows a user with network privileges to specify the preferred port speed and the maximum port speed for a VC Network. During profile creation and editing, any connection to this network will default to the preferred speed and will not allow a speed greater than the maximum to be chosen. Flex-10 allows a user with network privileges to specify the preferred port speed and maximum port speed for a connection with multiple networks (Mapped VLANs). During profile creation and editing, any connection to these multiple networks will default to the preferred speed and will not allow a speed greater than the maximum to be chosen. This setting is domain wide. Speed is not configurable on NICs that are not FlexNICs, even if they are capable of 2.5 Gb operation. However, non-FlexNIC 1Gb ports are supported by the VC Flex-10 Ethernet Module. 13
