Accelerating High-Speed Networking with Intel® I/O Acceleration Technology

The emergence of multi-Gigabit Ethernet allows data centers to adapt to the increasing bandwidth requirements of enterprise IT. To take full advantage of this network capacity, data center managers must consider the impact of high traffic volume on server resources. A compelling way of efficiently translating high bandwidth into increased throughput and enhanced quality of service is to take advantage of Intel® I/O Acceleration Technology (Intel® I/OAT), now available in the new dual-core and quad-core Intel® Xeon® processor-based server platforms. Intel I/OAT moves data more efficiently through these servers for fast, scalable, and reliable networking. Additionally, it provides network acceleration that scales seamlessly across multiple Ethernet ports, while providing a safe and flexible choice for IT managers due to its tight integration into popular operating systems.


Business success is becoming increasingly dependent on the rapid transfer, processing, compilation, and storage of data. To improve data transfers to and from applications, IT managers are investing in new networking and storage infrastructure to achieve higher performance. However, network I/O bottlenecks have emerged as the key IT challenge in realizing full value from server investments.

Until recently, the real nature and extent of I/O bottlenecks was not thoroughly understood. Most network issues could be resolved with faster servers, higher bandwidth network interface cards (NICs), and various networking techniques such as network segmentation. However, the volume of network traffic begun to outpace server capacity to manage that data. This increase in network traffic is due to the confluence of a variety of market trends.
