Scenario 2:2 - Flex-10 - VLAN Tagging (802.1Q)
with Multiple Shared Uplink Sets (SUS) and
Mapped VLANs - Windows 2008 Hyper-V
Overview
This scenario discusses the Flex-10 features provided in Virtual Connect. For an overview of Flex-10,
please refer to the following technology brief. HP Flex-10 technology brief;

Virtual Connect Flex-10 provides the ability to either present the 10Gb server NICs as single 10Gb NICs,
or divide each NIC into as many as 4 “physical function” NICs per NIC port. These physical function
NICs look to the server hardware and OS as physical NICs, have their own MAC address and can be
configured at speeds from 100Mb to 10Gb.
As shown in earlier scenarios, VLAN access can be handled in two different ways. Virtual Connect can
either pass VLAN/Non-VLAN traffic untouched to the host (Tunneling Mode) or Virtual Connect can
handle all VLAN tagging (Server Mapped VLANs). Each has their advantages as discussed in the
Introduction to Virtual Connect section, earlier in this document.
This scenario, using Map VLAN Tags, will focus on the Virtual Connect Flex-10 technology. In this
scenario we have two 10Gb uplinks configured with multiple VLANs. We will configure a Windows
2008R2 Hyper-V server with 4 NICs, 2 per NIC port, configured at various speeds. Some NICs will be
connected to a specific VLAN, so frames will be presented without tags, the other will be configured with
multiple networks/VLANs, were frames will be presented with tags. We will also show how the speed of
each NIC can be varied from speeds ranging between 100Mb to 10Gb.
