Introduction

As server virtualization technology becomes more prevalent within data centers, more dynamic performance is needed for network bandwidth to satisfy these demands. The Emulex 10GbE Virtual Fabric Adapters II and III for IBM® System x® can help you break the I/O bottleneck by allowing you to allocate bandwidth where it’s needed, delivering maximum application agility. Offering a full range of virtualization and convergence capabilities, the same network hardware offers Ethernet, iSCSI, or Fibre Channel over Ethernet with bandwidth that is allocated in increments from 100 Mb to 10 Gb. The next-generation Virtual Fabric Adapter for IBM System x is a fast, flexible, easy, and reliable solution for I/O virtualization.

The Emulex 10GbE Virtual Fabric Adapter II and Emulex Dual Port 10GbE SFP+ VFA III are shown in Figure 1 (these adapters look the same).

Did you know

With IBM Virtual Fabric, up to eight virtual network ports (vNICs) can be created with a single two-port 10 GbE network adapter. Converged protocols such as iSCSI and FCoE are also supported on selected configurations. By using a common infrastructure for Ethernet and SAN, and by virtualizing your network adapter, you can reduce your infrastructure capital expense.

Part number information

All adapters in the Emulex 10GbE Virtual Fabric Adapter family listed in Table 1 offer the same features and functions. There is a difference in the manner that they are field-upgradeable from an Ethernet-only-mode-of-operation to an Ethernet, FCoE and iSCSI mode-of-operation:

• VFA II adapters are designed to use a paper-key license where IBM provides a license security to be used at the Emulex web site once registered. Emulex provides the user with a different license key that is subsequently administered to the server. VFA II adapters are supported on the M2, M3 and X5 generation of IBM System x servers.
• VFA III adapters provide a much easier and efficient software license enablement process. IBM’s Feature on Demand process reduces the complexity of activating the license to just a few clicks of the mouse. VFA III is supported on the M4 generation of IBM system x Servers.

Customers and system designers need to note that VFA II and VFA III adapters, as well as the subset of VFA III PCIe, Integrated, and Mezzanine form-factors have different license key part numbers.

The Emulex Dual Port 10GbE SFP+ Embedded Adapter is designed to fit into a special slot in selected servers (see Table 4), allowing you to use the PCIe slots for other technologies. The adapter is shown in Figure 2.


Figure 2. Emulex Dual Port 10GbE SFP+ Embedded Adapter

The Emulex 10GbE Integrated Virtual Fabric Adapter II (Figure 3) has the same functional characteristics as the Emulex 10GbE Virtual Fabric Adapter II (Figure 1). This adapter must be purchased at the same time as the new IBM eX5 server (x3850 X5 and x3690 X5). It is factory installed into a standard PCIe slot, and is offered at a price savings compared to the Emulex 10GbE Virtual Fabric Adapter II . For this special price, there is a limit of one Emulex 10GbE Integrated Virtual Fabric Adapter II per system. The Emulex 10GbE Integrated Virtual Fabric Adapter II is shown in Figure 3.

Similarly, the Emulex Dual Port 10GbE SFP+ Integrated VFA III has the same functional characteristics as the Emulex Dual Port 10GbE SFP+ VFA III. The integrated adapter must be purchased at the same time as the new supported server (see Table 4). The integrated adapter is factory installed into a standard PCIe slot, and is offered at a price savings compared to the Emulex Dual Port 10GbE SFP+ VFA III. For this special price, there is a limit of one Emulex Dual Port 10GbE SFP+ Integrated VFA III per system.

Modes of operation

The Emulex 10GbE Virtual Fabric Adapter II and III support two types of virtual NIC (vNIC) operating modes, and a physical NIC (pNIC) operating mode:

• IBM Virtual Fabric Mode (also known as vNIC1 mode) will only work with an IBM RackSwitch G8124E and G8264. In this mode, the Emulex adapter communicates with the IBM switch to obtain vNIC parameters (using DCBX). A special tag is added within each data packet and is later removed by the NIC and/or switch for each vNIC group to maintain separation of the virtual data paths.

  In vNIC mode, each physical port is divided into four virtual ports for a maximum of eight (8) virtual NICs per adapter. The default bandwidth for each vNIC is 2.5 Gbps. Bandwidth for each vNIC can be configured via the IBM switch from 100 Mbps to 10 Gbps, up to a total of 10 Gb per physical port. The vNICs can also be configured to have 0 bandwidth if you must allocate the available bandwidth to fewer than four vNICs per physical port. In IBM Virtual Fabric Mode, you can change the bandwidth allocations through the IBM switch user interfaces without requiring a reboot of the server.

  vNIC bandwidth allocation and metering is performed by both the switch and the VFA. In such a case, a bidirectional virtual channel of an assigned bandwidth is established between them for every defined vNIC.

  In vNIC1 mode, storage protocols (FCoE and iSCSI) on vNICs are not supported.

• In Switch Independent Mode (also known as vNIC2 mode) the adapter works with any 10 Gb Ethernet switch. Switch Independent Mode offers the same capabilities as IBM Virtual Fabric Mode in terms of the number of vNICs and the bandwidth each can be configured to have. 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.

  vNIC bandwidth allocation and metering is only performed by VFA itself. In such a case, a unidirectional virtual channel is established where the bandwidth management is only performed for the outgoing traffic on a VFA side (server-to-switch). The incoming traffic (switch-to-server) uses the all available physical port bandwidth, as there is no metering performed on either the VFA or a switch side.

  In vNIC2 mode, when storage protocols are enabled on the Emulex 10GbE Virtual Fabric Adapters, six vNICs (three per physical port) are Ethernet, and two vNICs (one per physical port) are either iSCSI or FCoE.

• In pNIC mode the adapter operates as a standard dual-port 10 Gbps Ethernet adapter, and it functions with any 10 GbE switch. In pNIC mode, with the Emulex FCoE/iSCSI License, the card operates in a traditional Converged Network Adapter (CNA) mode with two Ethernet ports and two storage ports (iSCSI or FCoE) available to the operating system.

Although all adapters in the Emulex 10GbE Virtual Fabric Adapter family support pNIC, vNIC1 and vNIC2 modes, availability of each operating mode is also dependent on the top-of-rack switch and the network or storage protocol used (Ethernet only - no storage protocols, iSCSI or FCoE), as shown in the following table.
