Abstract

The Flex System™ CN4054 and CN4054R 10Gb Virtual Fabric Adapters are 4-port 10Gb converged network adapters (CNA) for Intel processor-based compute nodes that support Ethernet, iSCSI, and FCoE. The adapters support up to 16 virtual NIC (vNIC) devices, where each physical 10 GbE port can be divided into four virtual ports with flexible bandwidth allocation. The CN4054 Virtual Fabric Adapter Upgrade adds FCoE and iSCSI hardware initiator functionality to either adapter. The CN4054R adds support for compute nodes with the Intel Xeon E5-2600 v2 and v3 processors.

Introduction

The Flex System™ CN4054 and CN4054R 10Gb Virtual Fabric Adapters are 4-port 10Gb converged network adapters (CNAs) that support Ethernet, iSCSI, and FCoE. The adapters support up to 16 virtual NIC (vNIC) devices, where each physical 10 GbE port can be divided into four virtual ports with flexible bandwidth allocation. The CN4054 Virtual Fabric Adapter Upgrade adds FCoE and iSCSI hardware initiator functionality to either adapter. The CN4054R adds support for compute nodes with the Intel Xeon E5-2600 v2 and v3 processors.

Figure 1 shows the adapters (they have the same physical appearance).

Did you know?

This CN4054 is based on industry-standard PCIe architecture and offers the flexibility to operate as a Virtual NIC Fabric Adapter. Because this adapter supports up to 16 virtual NICs on a single quad-port Ethernet adapter, you see benefits in cost, power/cooling, and data center footprint by deploying less hardware. Compute nodes like the x240 support up to two of these adapters for a total of 32 virtual NICs per system.

Ordering information

The Flex System is a new category of computing that integrates multiple server architectures, networking, storage, and system management capability into a single system that is easy to deploy and manage. Flex System has full built-in virtualization support of servers, storage, and networking to speed provisioning and increased resiliency. In addition, it supports open industry standards, such as operating systems, networking and storage fabrics, virtualization, and system management protocols, to easily fit within existing and future data center environments. Flex System is scalable and extendable with multi-generation upgrades to protect and maximize IT investments.

Modes of operation

The CN4054 and CN4054R 10Gb Virtual Fabric Adapters support three vNIC modes of operation in addition to pNIC mode:

  • Virtual Fabric Mode. This mode only works in conjunction with any of the following switches installed in the chassis:
    • Flex System Fabric CN4093 10Gb Converged Scalable Switch
    • Flex System Fabric EN4093R 10Gb Scalable Switch
    • Flex System Fabric EN4093 10Gb Scalable Switch

    In this mode, the adapter communicates with the switch module to obtain vNIC parameters (using DCBX). Also, a special tag within each data packet is added and later removed by the NIC and switch for each vNIC group to maintain separation of the virtual channels.

    In vNIC mode, each physical port is divided into four virtual ports, providing a total of 16 virtual NICs per adapter. The default bandwidth for each vNIC is 2.5 Gbps. Bandwidth for each vNIC can be configured at the 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 eight vNICs. In Virtual Fabric Mode, you can change the bandwidth allocations through the switch user interfaces without requiring a reboot of the server.

    When storage protocols are enabled on the adapter (using CN4054 Virtual Fabric Adapter Upgrade, 90Y3558), six ports are Ethernet, and two ports are either iSCSI or FCoE

  • Switch Independent Mode, where the adapter works with the following switches:
    • Cisco Nexus B22 Fabric Extender for Flex System
    • Flex System EN4023 10Gb Scalable Switch
    • Flex System Fabric CN4093 10Gb Converged Scalable Switch
    • Flex System Fabric EN4093R 10Gb Scalable Switch
    • Flex System Fabric EN4093 10Gb Scalable Switch
    • Flex System Fabric SI4093 System Interconnect Module
    • Flex System EN4091 10Gb Ethernet Pass-thru and a top-of-rack (TOR) switch

    Switch Independent Mode offers the same capabilities as Virtual Fabric Mode in terms of the number of vNICs and the bandwidth that each can be configured to have. However, 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.

  • Unified Fabric Port (UFP) provides a feature rich solution compared to the original vNIC Virtual Fabric mode. Like Virtual Fabric mode vNIC, UFP allows carving up a single 10 Gb port into four virtual NICs (called vPorts in UFP). UFP also has a number of modes associated with it, including:
    • Tunnel mode: Provides Q-in-Q mode, where the vPort is customer VLAN-independent (very similar to vNIC Virtual Fabric Dedicated Uplink Mode)
    • Trunk mode: Provides a traditional 802.1Q trunk mode (multi-VLAN trunk link) to the virtual NIC (vPort) interface, i.e. permits host side tagging
    • Access mode: Provides a traditional access mode (single untagged VLAN) to the virtual NIC (vPort) interface which is similar to a physical port in access mode
    • FCoE mode: Provides FCoE functionality to the vPort
    • Auto-VLAN mode: Auto VLAN creation for Qbg and VMready environments

    Only one vPort (vPort 2) per physical port can be bound to FCoE. If FCoE is not desired, vPort 2 can be configured for one of the other modes.

  • In pNIC mode, the expansion card can operate as a standard 10 Gbps or 1 Gbps 4-port Ethernet expansion card. When in pNIC mode, the expansion card functions with all supported I/O modules.

    In pNIC mode, the adapter with the CN4054 Virtual Fabric Adapter Upgrade, 90Y3558, applied operates in traditional Converged Network Adapter (CNA) mode with four ports of Ethernet and four ports of storage (iSCSI or FCoE) available to the operating system.

See ServerProven at the following web address for the latest information about the expansion cards that are supported by each blade server type: http://www.lenovo.com/us/en/serverproven/flexsystem.shtml

I/O adapter cards are installed in the slot in supported servers, such as the x240, as highlighted in the following figure.

Figure 2. Location of the I/O adapter slots in the Flex System x240 Compute Node

Embedded 10Gb Virtual Fabric Adapter

Some models of the x240 include a two-port Embedded 10Gb Virtual Fabric Adapter (VFA, also known as LAN on Motherboard or LOM) built into the system board:

  • x240 models 8737-x2x and E5-2600 processors have an Embedded 10Gb Virtual Fabric Adapter based on the BE3 controller
  • x240 models 8737-x4x and E5-2600 v2 processors have an Embedded 10Gb Virtual Fabric Adapter based on the BE3R controller

Each x240 model that includes the embedded 10Gb VFA also has the Compute Node Fabric Connector installed in I/O connector 1 (and physically screwed onto the system board) to provide connectivity to the Enterprise Chassis midplane.

The Fabric Connector enables port 1 on the Embedded 10Gb VFA to be routed to I/O module bay 1 and port 2 to be routed to I/O module bay 2. The Fabric Connector can be unscrewed and removed, if required, to allow the installation of an I/O adapter on I/O connector 1.

The Embedded 10Gb VFA has two 10 GbE ports and has the same features as the 4-port CN4054 10Gb Virtual Fabric Adapter. The Embedded 10Gb VFA also supports iSCSI and FCoE using the upgrade license listed in the following table.

Supported I/O modules

These adapters can be installed in any I/O adapter slot of a supported Flex System compute node. One or two compatible 1 Gb or 10 Gb I/O modules must be installed in the corresponding I/O bays in the chassis. The following table lists the switches that are supported. When connected to the 1 Gb switch, the adapter will operate at 1 Gb speeds. When connected to the 40 Gb switch, the adapter will operate at 10 Gb speeds.

To maximize the number of adapter ports usable, you may also need to order switch upgrades to enable additional ports as listed in the table. Alternatively, for CN4093, EN4093R, and SI4093 switches, you can use Flexible Port Mapping, a new feature of Networking OS 7.8, that allows you to minimize the number of upgrades needed. See the Product Guides for the switches for more details:
https://lenovopress.com/servers/blades/networkmodule

The table also specifies how many ports of the adapter are supported once the indicated upgrades are applied. Switches should be installed in pairs to maximize the number of ports enabled and to provide redundant network connections.
