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.

White Paper Accelerating High-Speed Networking with Intel® I/O Acceleration Technology Introduction 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.

Accelerating High-Speed Networking with Intel® I/O Acceleration Technology White Paper Finding the Real I/O Bottlenecks Intel research and development teams found the real I/O bottlenecks when they examined the entire flow of a data packet as it is received, processed, and sent out by the server. Figure 1 illustrates this flow. The following numbered descriptions correspond to the circled numbers in the illustration: 4.
