Vendors are readying products to support RDMA over TCP/IP, a fledgling networking technology wending its way through standards bodies promising faster data transfers with less processor power.

Remote direct memory addressing over IP lets hardware devices share data directly among their respective memory chips, easing CPUs' processing burden. Specifically, information being passed does not require CPU processing. The process is similar to that of the Virtual Interface and InfiniBand technologies-which also use remote addressing. But this new wave of RDMA takes remote addressing over IP, which is cheaper and less complex, developers said.
