Rely on Intel® I/O Acceleration Technology

†

(Intel® I/OAT) to boost server I/O

throughput with fast, scalable, and reliable network acceleration in your Quad-Core

and Dual-Core Intel® Xeon® processor 5000

sequence-based servers. Intel I/OAT

is the new acceleration technology that outperforms the TCP offload engine

(TOE) approach and delivers leading network and I/O performance.

Intel I/OAT:

• Reduces CPU overhead by improving

data flow in the network, chipset, and host

operating system (OS), leaving more

application processing overhead.

• Is a safe and flexible I/O acceleration

choice with broad industry support, including

Microsoft Windows* Server 2003 and

leading Linux* distributions.

• Uses native protocol stacks to avoid

support risks of third-party network stacks.

• Preserves existing network capabilities,

like teaming, failover, and virtual LANs (VLANs).

• Significantly outperforms TOE throughput

and CPU utilization in network, teaming,

and application tests.

A Platform Solution System I/O throughput challenges are not isolated to the network connection. They’re present throughout the platform. TOE focuses on only the network connection by offloading TCP/IP processing to silicon on the network interface card (NIC). Intel I/OAT uses a platform-wide approach, integrating processor, chipset, and OS enhancements, significantly improving data movement through the platform.

Safer Choice — Supported by More OS Vendors Leading OS vendors support Intel I/OAT with native protocol stacks instead of relying on third-party stacks, making it a safer choice when it comes to maintenance and support. Plus, Intel I/OAT supports multiport teaming for redundancy, increased network throughput, and fewer NICs in a server.
