    Intel® Ethernet Converged Network Adapter X520

    Dual- and Single-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate
    Flexibility and Scalability in Virtual and Unified Storage Environments

     

     

     

    Overview
    Intel’s family of adapters, the Intel® Ethernet Converged Network Adapter X520 with SFP+ connectivity, are the most flexible and scalable Ethernet adapters for today’s demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers
    with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for
    10 Gbps connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualized and unified storage environments.

    Powered by Intel’s third-generation 10
    GbE network controller, the Intel® Ethernet
    82599 10 Gigabit Ethernet Controller, the X520 adapter family addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization, flexibility for LAN and SAN networking, and proven, reliable performance.

    Best Choice for Virtualization The explosive growth in virtualization is leading to an increasing demand for
    network performance. With more Virtual
    Machines (VMs) running on each multi-core server, networking traffic is dramatically increased, with each VM competing for available I/O bandwidth. Intel’s family
    of Intel Ethernet Converged Network
    Adapter X520 addresses networking
    bottlenecks in virtualized environments. These adapters enable network-intensive applications to achieve the performance expected in a virtualized environment.

    The Intel Ethernet X520 family of adapters provides the best networking performance available in the industry, whether the physical port is configured in an emulation mode using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine. In the emulation mode, Intel’s I/O technology, Virtual Machine Device queues1  (VMDq) optimizes
    network  performance by offloading data sorting and copying from the software Virtual Switch in the VMM to the Intel Ethernet 82599 10 Gigabit Controller. This configuration is best suited for a large number of VMs running standard applications that have limited bandwidth and latency requirements.

    For mission-critical applications, where dedicated I/O is required for maximum network performance, users can assign
    a dedicated virtual adapter port to a VM.
    Using the PCI-SIG SR-IOV capability on
    an Intel Ethernet X520 adapter provides direct VM connectivity and data protection across VMs. SR-IOV technology enables the data to bypass the software virtual switch and provides near-native performance. It assigns either physical or virtual I/O ports
    to individual VMs directly. This technology is best suited for applications that demand the highest I/O throughput and lowest latency performance such as database, storage, financial and other applications.

    PCI-SIG SR-IOV is a mechanism for devices to advertise their ability to be directly assigned to multiple virtual machines.
    SR-IOV enables the partitioning of a PCI Express* (PCIe) function into many virtual interfaces for the purpose of sharing the resources of a PCIe device in a virtual environment. These virtual interfaces are called Virtual Functions.
    Each virtual function can support a unique and separate data path for I/O-related functions within the PCIe hierarchy. Use
    of SR-IOV with a networking device, for example, enables the bandwidth of a single port (function) to be partitioned into smaller slices that can be allocated
    to specific VMs, or guests, via a standard
    interface.

    The Intel Ethernet X520 family of adapters delivers the same functionality and throughput as ten dual-port, one gigabit adapters, saving cost, power, and complexity. For more information on virtualization please go to: www.intel.com/go/vtc.

    unified Networking and Storage The family of Intel Ethernet X520 adapters lowers your data center total cost of ownership (TCO) by providing the
    ability to route LAN and SAN traffic over a
    single fabric.
    Support for fiber Channel over ethernet (fCoe)
    FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10 GbE networks while preserving its native protocol. The X520 adapters offer FCoE hardware acceleration to provide performance comparable to FC HBAs. The adapters support Data Center Bridging, also known as Converged Enhanced Ethernet (CEE), which enables customers to configure traffic classes and priorities to deliver a lossless Ethernet fabric.
    An Intel Ethernet Converged Network Adapter X520 reduces  TCO by eliminating redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.

    Support for iSCSi
    The adapters provide complete support for proven native OS and VMM iSCSI initiators as well as iSCSI boot. Historically, CRC32C computation has degraded
    system performance, but now with the CRC instruction set included in the latest Intel® Xeon® processors, CRC validation is possible with minimal impact to network throughput while delivering superior data integrity.

    The Intel Ethernet family of X520 adapters do it all: 10 Gigabit LAN, FCoE, and iSCSI; truly delivering on the promise of unified networking.
    reliable performance
    The family of X520 adapters includes a number of advanced features that enable it to provide industry-leading performance and reliability.

    Security Optimizations
    The adapters support IPsec offload for Microsoft’s* Network Access Protection (NAP), Active Directory,* and future security capabilities in Windows 7*. An X520 adapter enables customers to run a secure network environment without sacrificing performance.

    pCie v2.0 (5 Gt/s)
    PCIe v2.0 (5 GT/s) support enables
    customers to take full advantage of 10
    GbE by providing a maximum of 20 Gbps bi-directional throughput per port on a single dual port card.

    designed for Multi-core processors Support for technologies such as multiple queues, receive-side scaling,
    multiple  MSI-X vectors, and Low Latency
    Interrupts enable the X520 adapters to provide high-performance, 10 Gigabit connectivity in multi-core server blades. These technologies distribute network processing across multiple CPU cores, improving overall performance.
    For today’s demanding virtualized data center environments, the new family of X520 adapters deliver ultimate flexibility and scalability.

  • 支持连接的英特尔® 虚拟化技术

    对虚拟化的 I/O 进行优化,以实现平衡的服务器性能
    支持连接的英特尔® 虚拟化技术 (英特尔® VT-c) 能降低 CPU 使用量,缩短延迟,并提高网络吞吐量。英特尔® VT-c 是英特尔® 虚拟化技术的关键组件技术之一。
    虚拟机设备队列 (VMDQ) 通过将通信量排序从管理程序的虚拟交换机分载至英特尔® 以太网控制器来增强流量管理。VMDQ 通过与 VMware NetQueue* 或 Microsoft Virtual Machine Queues* 协同工作,在英特尔以太网控制器的多个硬件队列上支持流量导向和平衡带宽分配。
    PCI-SIG 单根 I/O 虚拟化 (SR-IOV) 能将单个英特尔® 以太网服务器适配器端口分为多个虚拟功能。IT 管理员可以使用这些虚拟端口来创建与虚拟机的多个隔离连接

    基于英特尔® 以太网的统一网络解决方案

    可信, 价格合理的连接功能
    基于英特尔® 以太网的统一网络解决方案通过单个英特尔® 以太网万兆位聚合网络适配器提供全面的 LAN 和 SAN 连接。
    英特尔® 以太网聚合网络适配器支持 NFS、iSCSI 和太网光纤通道 (FCoE),可简化数据中心基础设施,并且不需要价格昂贵,针对特定存储的适配器。
    英特尔® 以太网聚合网络适配器使用操作系统或管理程序的本地 iSCSI 和 FCoE 支持以提供简单而可扩展的 SAN 连接功能。英特尔® 以太网控制器中的智能硬件分载能在不依赖基于复杂的专有硬件解决方案的情况下加快通信量。

    iWARP 帮助实现低延迟
    由于虚拟化、大数据应用、Web 2.0 服务和日益增长的实时应用,低延迟对于一家企业而言越来越重要。
    对于许多应用而言,完成任务依赖于向服务器调用数据或数据中心其他部分的存储。随着东西区域流量日益增长,需要低延迟基础架构才能够满足应用响应时间需求。
    对于需要低延迟的数据中心和云应用而言,网络环境也在不断变化。InfiniBand* 不是唯一的选择。iWARP 日渐成为主流网络技术,它可对许多网络应用的性能和效率产生很大影响。
    由于企业向以太网大量投资,iWARP 成为替代 Infiniband 的理想解决方案。如果考虑到安装和维护一个完全独立的基础架构,InfiniBand 则更没有优势。
    iWARP 使用现有的以太网基础架构。现在,网络管理员可以在服务器中安装支持 iWARP 的以太网适配器卡,Microsoft Windows* Server 2012 将自动利用可用的 RDMA (远程直接内存访问)方法。因为 iWARP 的运行位置是 TCP/IP,所以无需对现有的交换机和路由器网络基础架构做任何改动。
    实际的测试显示,iWARP 与 InfiniBand 相当甚至更出色。
    将来的英特尔® 服务器芯片组借助 iWARP 的功能将支持 10 GbE 和更快的以太网,从而实现较高的吞吐能力、较低的延迟性能并使用较少的 CPU 利用率。阅读白皮书,了解更多关于性能的信息。
