Page 2: Abstract
Abstract This technology brief examines HP Flex-10 for Virtual Connect technology. This paper takes an in- depth look at the HP hardware and software technology that comprises Flex-10. It also explores Flex- 10’s functional association with HP Virtual Connect (VC), and examines how Flex-10 technology enhances, and is compatible with, current 10GbE architecture. -

data traffic on the multiple networks employed in a typical data center. These heterogeneous networks, listed in Table 1, carry data server communication, management, computing, and storage. Table 1. Typical data center bandwidth requirements Network Data Traffic Bandwidth Communication – All business communication that is based Email, file sharing, web services, on Internet Protocol (IP). -

Bandwidth constraints on multiple, concurrent production applications such as iSCSI and virtual machine migration Limited separation of production applications Limited dedicated redundant backup No room for advanced services such as NIC teaming As an example, HP ProLiant c-Class blade servers limit the number of interconnect bay modules, requiring a trade-off among Fibre Channel, Ethernet, InfiniBand, and other network types. -
Page 5: Server-Side Vlan Tags
Server-Side VLAN tags These VLAN tags direct virtual machine VLANs to defined Virtual Connect networks (vNets) inside of the Flex-10 interconnect module. Private networks Private networks act to keep traffic secure and isolated between servers. Flex-10 architectural overview Flex-10 technology introduces a unique approach to managing 10GbE networks. The Flex-10 architecture is key to understanding how these management objectives are achieved. -
Page 6: Flex-10 10Gb Ethernet Module Design
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. -

FlexNICs The 10Gb Flex-10 LOM and mezzanine cards are dual 10Gb port cords. The BL495c G5 server with Flex-10-capable LOM is shown in Figure 6, and the HP NC532m Flex-10 10GbE Network Adapter is shown in Figure 7. Each 10Gb server port can be configured from one to a maximum of four individual FlexNICs and up to eight FlexNICs for each dual port LOM or mezzanine card. -

Flex-10 Ethernet Module The HP Virtual Connect Flex-10 10Gb Ethernet Module shown in Figure 8 is the only Interconnect Module that manages the server connections to the data center network. The Flex-10 10Gb Ethernet Module recognizes and manages each FlexNIC as part of a server profile Figure 8. -

Figure 9. HP SFP+ module with copper cabling The SFP+ with copper cabling can be used with the SFP+ ports on the Flex-10 Enet module and is thinner than CX4 cabling. This cable configuration is ideal for stacking modules within an enclosure. Fiber Optic uplink cables can be sourced from third-party vendors who meet industry-standard specifications for Ethernet cable types. - Page 13 VC-assigned or server factory default MAC addresses may be used for FlexNICs. When using server factory default MAC addresses, FlexNICs will still have unique MAC addresses. For example, the BL495 BladeSystem server has 8 factory-assigned MAC addresses. Each FlexNIC on a physical port can be assigned to a different vNet or remain unassigned, but multiple FlexNICs on a single port cannot be assigned to the same vNet.

Page 14: Vc Operation In The Flex-10 Environment
VC operation in the Flex-10 environment VC has numerous functions that are associated with server NIC connectivity. Wherever possible, the goal is to treat the FlexNIC exactly like a server NIC, but this is not always possible. Table 2 describes which VC features will be affected. Table 2. -
Page 15: Summary
PXE is only supported on first FlexNIC of a Physical Port. Only VC Flex-10 Enet modules running Flex-10 compliant VCM firmware support FlexNICs. Summary Flex-10 technology introduces a hardware-based solution to address the issue of data management on 10GbE networks. Flex-10 increases the number of NICs in virtual machine server configurations which reduces cost and adds flexibility. -
