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. Figure 2.

This pathway is enabled by implementing the 10GBase-KR (IEEE specification 802.3ap) one lane, serial backplane connection standard. 6
