NetDMA provides operating system support for direct memory access (DMA) offload. TCP/IP uses NetDMA to relieve the CPU from copying received data into application buffers, reducing CPU load.
NetDMA must be enabled in BIOS.
CPU must support Intel I/O Acceleration Technology (I/OAT).
You cannot use TCP Chimney Offload and NetDMA together.
|Itanium-based versions of the Windows operating systems do not support NETDMA|
You can use NetDMA to reduce CPU load on computers that are running network intensive applications. NetDMA provides network scalability for computers with high throughput and multiple network interfaces.
