Flex-10 10Gb Ethernet Module design

Each FlexNIC can be mapped to a different Virtual Connect network (vNet) as shown in Figure 2.
Traffic for each FlexNIC is isolated by means of a VLAN tag managed by the FlexNIC. The actual
value of the outer VLAN tag for each FlexNIC is set by Virtual Connect. Each BladeSystem c7000
enclosure can support multiple single-wide Flex-10 Ethernet (Enet) modules within a single VC domain.
The ProLiant c3000 enclosure also supports Flex-10 Enet modules.

Packets that have been tagged and isolated by VC and the FlexNICs then move from the Flex-10
device (LOM or mezzanine card) to the Flex-10 VC Enet module on a single pathway. This pathway is
enabled by implementing the 10GBase-KR (IEEE specification 802.3ap) one lane, serial backplane
connection standard.
