IWARP/RDMA
iWARP provides converged fabric services with low latency for data centers using Remote Direct Memory Access (RDMA) over Ethernet. The key components of iWARP that ensure low latency are kernel bypass, direct data placement, and transport acceleration.

Intel® Data Direct I/O Technology
Intel® Data Direct I/O Technology is a platform technology that improves the efficiency of I/O data processing for the delivery and utilization of data by I/O devices. With Intel Data Direct I/O Technology, Intel® server adapters communicate directly with the processor cache without detouring through system memory, reducing latency, increasing the system's I/O bandwidth, and lowering power consumption.

Suitable for PCI-SIG* SR-IOV
Single-root I/O virtualization involves the native (direct) sharing of a single I/O resource among multiple virtual machines.
