    Based  on the new  Intel® 82580  Gigabit Ethernet  Controller,

    the Intel®  Ethernet  I340 Server  Adapter  is Intel’s fourth  gener-

    ation of  PCIe GbE  adapter. This  adapter showcases  the  indus-

    The I/O technologies on a multi-core platform make use of the

    multiple queues and multiple interrupt vectors available on the

    network controller. These queues and interrupt vectors help in load

    balancing the data and interrupts amongst themselves in order

    to lower the load on the processors and improve overall system

    performance. For example, depending upon the latency sensitivity

    of the data, the low latency interrupts feature can bypass the time

    interval for specific TCP ports or for flagged packets to give certain

    types of data streams the least amount of latency to the applica-


    try’s  first fully  integrated  quad-port  PCIe Gen2  GbE controller,

    providing  a smaller  footprint  and lower  power dissipation.    In

    addition,  the Intel®  Ethernet  I340 Server  Adapter  offers ad-

    vanced  features, including   support  for multi-core  processors

    and server  virtualization,   as well as  a scalable  PCI Express  Gen

    2.0 interface.   Intel’s  first  eco-friendly  halogen-free  board  com-

    bines  low-power and  cost for  the best  price/performance   ratio

    in a quad-port   solution  available  today.



    Working to create a more environmentally sustainable future,

    Intel is pleased to introduce its first halogen-free Ethernet Server

    Adapter.  The transition to halogen-free products is not govern-

    ment mandated, but driven by Intel’s goal to eliminate the use of

    environmentally sensitive materials.  The move to halogen-free

    products marks another step in our continual march toward mini-

    mizing the environmental footprint of Intel’s products, processes,

    and technologies.

    Intel I/O Acceleration Technology (Intel I/OAT) is a suite of

    features that improves data acceleration  across the platform,

    from networking devices  to the chipset and processors,  which

    helps to improve system performance  and application response

    times. The different  features include MSI-X, Low-Latency

    Interrupts, Receive Side Scaling  (RSS), and others.  MSI-X helps

    in load-balancing  I/O interrupts across multiple  processor cores,

    and Low Latency Interrupts  can provide certain data streams a

    non-modulated path  directly to the application. RSS  directs the

    interrupts to a specific  processor core based on the application’s


    Designed for Multi-Core Processors

    This quad-port  adapter provides high-performing,  multi-port

    Gigabit connectivity  in a multi-core platform as well as in  a

    virtualized environment.  In a multi-core platform, the  adapter

    supports technologies  such as MSI-X, and Low Latency Inter-

    rupts that help accelerate data  across the platform, improving

    application response  times.

    Support for iSCSI

    Intel® Ethernet server adapters  with native iSCSI initiators built

    into Microsoft® Windows®, Linux®, and  VMware® ESX platforms


    Applies only  to halogenated flame  retardants and  PVC in components.   Halo-

    gens are below  900 ppm bromine  and 900 ppm chlorine.



    provide a simple, dependable,  cost-effective way to connect

    to LANs and iSCSI  SANs. These native initiators are broadly

    tested using multiple generations  of operating systems, storage

    systems, and OS tools to help  ensure reliability and ease of use.

    Standardizing on Intel Ethernet server  adapters for iSCSI allows

    administrators to use  a single initiator, TCP/IP stack, and set of

    management tools and IT policies.  In addition, the I340  server

    adapter includes a number  of hardware features designed to

    accelerate iSCSI traffic  and enhance data processing. For  example,

    TCP segmentation offload,  Receive side coalescing (RSC),  and

    checksum offload  capabilities help reduce processor  utilization,

    increase throughput,  and deliver exceptional iSCSI performance.

    The adapters are designed  to flexibly scale workloads across

    multi-core processor–based  systems. Finally, using native OS

    initiators, an Intel® Ethernet  I340 Server Adapter enables support

    for the CRC-32 digest instruction  set included in the Intel® Xeon®

    processor 5500 series,  which improves transmission reliablity  and

    thus delivers an enterprise  class iSCSI solution for the IT  customer.

    it is recommended that a virtualized  physical server  needs at least

    six GbE ports to satisfy  the I/O requirement demands..

    Virtual Machine  Device queues (VMDq)

    VMDq reduces I/O overhead  on the hypervisor in a virtualized

    server by performing  data sorting and coalescing  in the network

    silicon. VMDq technology  makes use of multiple queues in the

    network controller. As data packets  enter the network adapter,

    they are sorted, and  packets traveling to the same destination

    (or virtual machine) get grouped  together in a single queue. The

    packets are then sent to the hypervisor,  which directs them to

    their respective virtual  machines. Relieving the  hypervisor of

    packet filtering and sorting  improves overall CPU usage and

    throughput levels.

    Reliable Performance

    The server adapter includes  a number of advanced features  that

    enable it to provide industry-leading  quad-port  1GbE performance

    and reliability. With over 25 years  of experience shipping Ethernet

    adapters, Intel offers unmatched  quality and design.

    Optimized for Virtualization

    PCIe* v2.0 (5 GT/s)

    The Intel® Ethernet I340 Server  Adapter showcases a suite of

    hardware assists that improves  overall system performance

    by lowering the I/O overhead  in a virtualized environment.  This

    optimizes CPU usage, reduces  system latency, and improves I/O

    throughput. These  features include:

    PCIe v2.0 (5 GT/s) support  enables customers to take full

    advantage of the 1 GbE by providing  a maximum of 2.0 Gbps

    bi-directional  throughput per port on a single  quad-port card.

    For today’s demanding  virtualized data center environments,

    the new Intel®  Ethernet I340  Server  Adapter delivers ultimate

    flexibility and scalability.

    • Virtual Machine  Device Queues (VMDq)

    • Intel® I/O Acceleration Technology (Intel® I/OAT)

    Use of multi-port  adapters in a virtualized environment  is very

    important because  of the need to provide redundancy  and

    data connectivity  for the applications/workloads  in the virtual

    machines. Due to the  need for redundancy and data connectivity,
