Memory copy using Intel Quickdata technology

Vasudev_J_ — Thu, 12 Jun 2014 06:36:36 GMT

I am doing the experimentation on improving the memory-to-memory copy performance (NIC to memory also, but secondary). I have seen that Intel I/OAT provides the Quickdata technology feature to offload the copies using DMA engine.

1. I haven't seen many i/oat related discussions in past few years, is it replaced with other more improved technology in new chipsets?

2. I need the Quickdata technology feature, how can I detect that my processor has Quickdata technology? In lspci, it is not showing anything related to Intel Quickdata Technology.

3. Which latest system/server should I buy to get the Quickdata Technology feature? If you can tell about NIC to memory copy (similar to TCP/IP offloads in i/oat), that will be very helpful.

Many thanks in advance.
