HP 1.10GB Virtual Connect Ethernet Module for c-Class BladeSystem - Manual (Page 99)

Server management 99
Although these four FlexNICs share a single 10Gb physical interface, Virtual Connect is able to keep traffic
for the FlexNICs isolated, and each FlexNIC is assigned to a different Virtual Connect network. Each FlexNIC
can be assigned a different bandwidth (from 100Mb to 10Gb), which is enforced by hardware mechanisms.
A Flex-10 capable NIC (embedded Ethernet or mezzanine card) only enumerates as four FlexNICs per
10Gb port if that NIC is directly connected to an HP Virtual Connect Flex-10 Module or an empty
interconnect bay. Eight FlexNICs are enumerated when connected to an empty interconnect bay because it
is assumed that an HP Virtual Connect Flex-10 Module will be installed in that bay. If a Flex-10-capable NIC
is connected to a Virtual Connect interconnect module that does not support Flex-10 or a non-Virtual Connect
interconnect module, that NIC enumerates as only one Ethernet device per physical port.
The following table shows an example of how a BL495c Flex-10 embedded Ethernet device would be
enumerated when connected to different interconnects. For more information about mapping between
servers and interconnect bays, see the HP BladeSystem c-Class enclosure documentation on the HP website
( http://www.hp.com/go/bladesystem/documentation ).
