Accelerating High-Speed Networking with Intel® I/O Acceleration Technology White Paper
Conclusion
In summary, Intel I/OAT improves network application responsiveness
by moving network data more efficiently through Dual-Core and
Quad-Core Intel Xeon processor-based servers to provide fast,
scalable, and reliable network acceleration for the majority of
today’s data center environments. This translates to the following
significant areas of benefit for IT data centers:
• Fast. A primary benefit of Intel I/OAT is that it significantly reduces
CPU overhead, freeing resources for more critical compute tasks.
Intel I/OAT uses server processors more efficiently by leveraging
architectural improvements within the CPU, chipset (Intel Quick
Data Technology), network controller, and firmware to minimize
performance-limiting bottlenecks.
• Scalable. Intel I/OAT scales seamlessly across multiple GbE ports
(up to eight ports), and can scale up to 10GbE, while maintaining
power and thermal characteristics similar to those of a standard
gigabit network adapter.
• Reliable. Intel I/OAT is a safe and flexible choice because it
is tightly integrated into popular operating systems such as
Microsoft Windows Server 2003 and Linux, avoiding the support
risks associated with relying on third-party hardware vendors for
network stack updates. Intel I/OAT also preserves critical network
capabilities, such as teaming and failover, by maintaining control
of the network stack processing within the CPU—where it belongs.
This results in reduced support risks for IT departments.
