Count Microsoft as firmly behind Intel's I/O Acceleration Technology (I/OAT), part of the company's Caneland platform aimed at bumping up TCP/IP and messaging capabilities.
Redmond is on the record as including native support for I/OAT in Windows Server 2008, the word coming from none other than Henry Sanders, GM of Microsoft Windows Networking.
I/OAT is Intel's version of an offload engine, allowing the Zeon processor to retain TCP/IP workloads rather than sending them off to a dedicated chip. The problem is that the I/OAT format requires coordination between the CPU, chipset, software compilers and the operating system.
This isn't Microsoft's first experience with I/OAT. In 2005, the company included it in the Scalable Networking Pack for Windows Server 2003, but this is the first time it's been written directly into the OS.
