The key iWARP components that deliver low-latency are Kernel Bypass. Direct Data Placement. and Transport Acceleration.Intel® Data Direct I/O TechnologyIntel® Data Direct I/O Technology is a platform technology that improves I/O data processing efficiency for data delivery and data consumption from I/O devices. With Intel DDIO.
SR-IOV provides a mechanism by which a Single Root Function (for example a single Ethernet Port) can appear to be multiple separate physical devices.Flexible Port PartitioningFlexible Port Partitioning (FPP) technology utilizes industry standard PCI SIG SR-IOV to efficiently divide your physical Ethernet device into multiple virtual devices. providing Quality of Service by ensuring each process is assigned to a Virtual Function and is provided a fair share of the bandwidth.Virtual Machine Device Queues (VMDq)Virtual Machine Device Queues (VMDq) is a technology designed to offload some of the switching done in the VMM (Virtual Machine Monitor) to networking hardware specifically designed for this function.
VMDq drastically reduces overhead associated with I/O switching in the VMM which greatly improves throughput and overall system performance
