IWARP/RDMA
iWARP offers convergent, low-latency fabric services for data centres through Remote Direct Memory Access (RDMA) via Ethernet. The key iWARP components 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 data transfer and utilisation of I/O devices. With Intel DDIO, Intel server adapters and controllers communicate directly with the processor cache without going through system memory, which reduces latency, increases system I/O bandwidth and reduces power consumption.

PCI-SIG SR-IOV capable
Single-Root I/O Virtualisation (SR-IOV) enables the native sharing of a single I/O resource between multiple virtual machines. SR-IOV provides a mechanism by which a single root function (for example, a single Ethernet port) can appear as multiple separate physical devices.

Flexible port partitioning
Flexible Port Partitioning (FPP) technology utilises the industry standard PCI SIG SR-IOV standard to efficiently partition your physical Ethernet device into multiple virtual devices. It provides quality of service by ensuring that each process is assigned to a virtual function and receives a fair share of the bandwidth.

Virtual Machine Device Queues (VMDq)
Virtual Machine Device Queues (VMDq) is a technology developed to offload some of the switching performed in the Virtual Machine Monitor (VMM) to network hardware specifically designed for this function. VMDq significantly reduces the overhead associated with I/O switching in the VMM, which greatly improves the throughput rate and overall performance of the system.
