Introduction
The Broadcom 2-port 10Gb Virtual Fabric Adapter for BladeCenter is a part of Lenovo's comprehensive networking portfolio of 1 GbE and 10 GbE adapters and delivers industry-leading performance and scalability per watt, reducing requirements for power and cooling. Protocol offloads enable efficient use of computing resources, support more virtual machines per CPU, and reduce the number of servers required to support data center demands. These adapters allow IBM clients to simplify their I/O infrastructure by reducing the number of switches needed inside the chassis.
The Broadcom 2-port 10 Gb Virtual Fabric Adapter can be configured to operate in virtual NIC mode, where up to eight virtual NIC devices can be enabled. Each physical 10 Gbps port can be divided into four virtual ports with bandwidth allocation in 100 Mbps increments to the maximum 10 Gbps per physical port.
Figure 1 shows the Broadcom 2-port 10Gb Virtual Fabric Adapter for BladeCenter.

Did you know?
The Broadcom 2-port 10Gb Virtual Fabric Adapter can operate in pNIC mode as regular 1Gb or 10Gb Ethernet adapter, or in switch-independent vNIC mode where it can be divided into up to eight virtual adapters (up to four per physical port), which can be used either with integrated switches such as the Virtual Fabric 10Gb Switch Module and the Cisco Nexus 4001I Switch Module, or with other top-of-rack switches via the 10 Gb Ethernet Pass-Thru Module.

- Supports Wake-on-LAN
- Supports SOL and cKVM
Virtual NIC (vNIC) support is as follows:
- Supports IBM Virtual Fabric in Switch Independent Mode - Eight virtual ports (four per physical port),
- uEFI based vNIC configuration
- vNIC port specific quality of service configuration
- Supporting vNIC capability, all included in base function; no firmware key required
Performance features are as follows:
- TCP stateful offload (Microsoft Chimney / TOE)
- TCP and UDP stateless offloads over IPv4 and IPv6
- Interrupt coalescing
- Message Signal Interrupts (MSI, MSI-X)
- RX/TX multiqueue
- VMware NetQueue and Microsoft VMQ
Modes of operation
The Broadcom 2-port 10 Gb Virtual Fabric Adapter supports two modes, Switch Independent Virtual NIC (vNIC) Mode and the regular physical NIC (pNIC) mode:
- Switch Independent vNIC Mode: In vNIC mode, each physical port appears to the blade server as four virtual NICs. The default bandwidth for each vNIC is 2.5 Gbps. Bandwidth for each vNIC can be configured from 100 Mbps to 10 Gbps.
The total bandwidth of the four vNICs per port cannot exceed 10 Gbps, however, the Broadcom adapter supports oversubscription, whereby the aggregate bandwidth can be as high as 40 Gbps (4x10 Gbps) allowing any of the vNICs to consume as much as 10 Gbps where there is no contention or less when there is (based on the weight assigned to that vNIC). vNICs can also be configured to have 0 bandwidth if you must allocate the available bandwidth to fewer than eight vNICs.
The adapter works with the following switches:
- Virtual Fabric 10Gb Switch Module
- Cisco Nexus 4001I Switch Module
- 10Gb Ethernet Pass-Thru Module and a top-of-rack (TOR) switch.
These switches are installed in I/O module bays 7 and 9 in the chassis. Switch Independent Mode extends the existing customer VLANs to the virtual NIC interfaces. The IEEE 802.1Q VLAN tag is essential to the separation of the vNIC groups by the NIC adapter or driver and the switch. The VLAN tags are added to the packet by the applications or drivers at each end station rather than by the switch.Note: The Broadcom 2-port 10 Gb Virtual Fabric Adapter does not support IBM Virtual Fabric Mode.
- Physical NIC (pNIC) mode: In pNIC mode, the expansion card can operate as a standard 10 Gbps or 1 Gbps 2-port Ethernet expansion card. When in pNIC mode, the expansion card functions with any available 10 Gb switch or 10 Gb pass-thru module installed in I/O module bays 7 and 9.
Operating environment
The expansion card is supported in the following environments:
- Temperature: 10 to 35 °C (50 to 95 °F)
- Relative humidity: 8 to 80% (non-condensing)
- Maximum altitude: 2,133 m ( 7,000 ft)

The I/O module listed in Table 3 is supported in BladeCenter H and BladeCenter HT chassis only.
In BladeCenter H, the ports of CFFh cards are routed through the midplane to I/O bays 7, 8, 9, and 10, as shown in Figure 3. The BladeCenter HT is similar in that the CFFh cards are also routed through the midplane to I/O bays 7, 8, 9, and 10.
Figure 3. BladeCenter H I/O topology showing the I/O paths from CFFh expansion cards
The Broadcom 2-port 10Gb Virtual Fabric Adapter requires that two I/O modules be installed in bays 7 and 9 of the BladeCenter H and HT chassis (Table 4).

Popular configurations
This section shows a configuration that uses the Broadcom 2-port 10Gb Virtual Fabric Adapter.
Figure 4 shows the use of the Broadcom 2-port 10Gb Virtual Fabric Adapter to route either two physical ports or eight virtual ports to the Virtual Fabric 10Gb Switch Modules installed in the BladeCenter chassis. Two Virtual Fabric 10Gb Switch Modules are installed in bay 7 and bay 9 of the BladeCenter H chassis. All connections between the controller, card, and the switch modules are internal to the chassis. No cabling is needed.
Figure 4. Configuration using the Broadcom 2-port 10Gb Virtual Fabric Adapter
Depending on how you configure the switch and expansion card, you can get either:
- Eight virtual Ethernet ports (vNIC mode). Each virtual port can be configured to operate at 100 Mbps to 10 Gbps, up to a total maximum of 10 Gb per physical port. The default bandwidth is 2.5 Gb per virtual port.
- Two 1 Gb or 10 Gb Ethernet ports (pNIC mode).
The components used in this configuration are listed in Table 5.
