The total actual shareable bandwidth cannot exceed 10Gb; however, the preferred speed and maximum
bandwidth settings can exceed a total of 10Gb, allowing ports to take advantage of unused bandwidth
when available.
A Flex-10 capable NIC (embedded Ethernet or mezzanine card) is seen as eight FlexNICs per 10Gb port if
that NIC is directly connected to an HP Virtual Connect Flex-10 or FlexFabric module. Eight FlexNICs are
indicated when connected to an empty interconnect bay because it is assumed that an HP Virtual Connect
Flex-10 or FlexFabric 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 is seen as only one Ethernet device per physical port.
The following table shows an example of how a BL495c Flex-10 embedded dual port NIC would be
presented 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 Installing tab of the
HP BladeSystem Technical Resources website

SR-IOV
Beginning with VC 4.10, VC supports SR-IOV by automatically allocating all Virtual Functions (VFs) to the
third Physical Function (PF) on each port of the server. VC enables SR-IOV on certain BLOMs, mezzanine
cards for Gen8 servers, and LOMs for G7 servers. SR-IOV is not enabled on Integrity servers. Starting with
VC 4.10, the following are FFAs supported:
•
HP Flex-10 10Gb 2-port 530FLB Adapter
•
HP FlexFabric 10Gb 2-port 534FLB Adapter
•
HP Flex-10 10Gb 2-port 530M Adapter
