Intel® I/O Acceleration Technology (Intel® I/OAT) is a new Intel platform network technology that accelerates, optimizes and seamlessly scales enterprise servers on Microsoft Windows Server* and Linux* operating systems.
Acceleration moves networking data to applications faster.
Optimization allows you to increase the load on your servers without increasing power consumption.
Seamless multiple port scaling gives you increased networking throughput from teaming along with reliable server and application availability.
Implementing Intel I/OAT requires no change to your existing network configuration or existing security implementations.
This is a platform-level solution for data movement. Thus, several ingredients are necessary for a system to be Intel I/OAT capable:
Platform | The platform must be based on the Intel® 5000 Series Chipset with an Intel I/OAT-compatible BIOS. |
Operating System |
|
Network Connectivity Hardware | Intel I/OAT is supported on specific server adapters and network connections
available from Intel and other vendors. If you have multiple network
adapters in your system, Intel I/OAT will operate automatically on the
compatible models, while non-compatible adapters will pass traffic
normally. Supported Intel adapters include:
|
Drivers and Connectivity Software | Intel I/OAT becomes active when all required software
support is loaded & enabled.

NOTE: At least one Intel I/OAT-capable port must be enabled when your system starts up. If no Intel I/OAT-capable ports are enabled at system startup, the IOATDMA driver will not register with NDIS and Intel I/OAT-capable ports enabled after system startup will show no DMA activity. Enable an Intel I/OAT-capable port and reboot to resolve this issue. |
Your system memory channels should be fully populated. Intel recommends a minimum of 4 GB of system memory or 1 GB per channel. Refer to your system guide for specific information regarding memory channels.
In a Windows environment, the following advanced settings must be enabled (see the Intel® PROSet link in the left pane):
The System Check Utility (ioatchk.exe) is a stand alone application that checks your system for Intel I/OAT compatibility. The utility can be found on the Intel support website and on the Intel LAN driver CD in the \PLATFORM\IOATDMA\Win32 or \PLATFORM\IOATDMA\Winx64 subdirectories.
