for implementation only with supported HP BladeSystem servers. See http://h18004.www1.hp.com/products/blades/components/ethernet/1010gb-f/questionsanswers.html#c1 for HP products that currently support Flex-10. The Flex-10 technology enables VC to configure a single 10Gb network port of BladeSystem - HP ProLiant BL35p | HP Flex-10 technology - Page 3
as managing these virtual components. The degree of performance degradation is dependent largely on the number of virtualized servers supported by the physical host server and the level of management services in use. NIC limitations When servers are consolidated using virtual machine software, it is - HP ProLiant BL35p | HP Flex-10 technology - Page 4
services such as NIC teaming2 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 Motherboard (LOM) devices and mezzanine cards that support up to four FlexNICs on each port. - HP ProLiant BL35p | HP Flex-10 technology - Page 5
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 - HP ProLiant BL35p | HP Flex-10 technology - Page 6
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.

devices have two ports as shown in Figure 2. NOTE: Mapping is supported on current VC, non-Flex-10, 1G NICs as well. Server VLAN mapping was introduced in the 1.31 version of Virtual Connect Manager firmware and that support extends to the individual FlexNICs in the Flex-10 environment.

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 - HP ProLiant BL35p | HP Flex-10 technology - Page 11

see Table A2 in the appendix. VC support for Flex-10 The goal of VC support is to extend to Flex-10 and FlexNICs the full range of services and management capabilities associated with server NIC operation. Recommended firmware For optimal operation of HP Virtual Connect Manager (VCM) with Flex-10 - HP ProLiant BL35p | HP Flex-10 technology - Page 13
VC support for Flex-10: Up to 24 NIC ports are possible per VC server profile (for a single, half height BladeSystem server). Existing (pre-Flex-10) server profiles with multiple networks (Mapped VLANs). During profile creation and editing, any connection to these multiple networks will default - HP ProLiant BL35p | HP Flex-10 technology - Page 14
a server reboot. The Flex-10 initial release will support the Virtual Connect Manager "shared server link" feature for each FlexNIC. This section describes additional limitations present in the initial release of Flex-10: The same network cannot be assigned to more than one FlexNIC. VCM cannot drop - HP ProLiant BL35p | HP Flex-10 technology - Page 15
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 -effective solution for virtual machine server configurations requiring four or more NICs - HP ProLiant BL35p | HP Flex-10 technology - Page 16
