Intel Ethernet Network Adapter X710-DA2 for OCP

IWARP/RDMA
iWARP delivers converged, low-latency fabric services to data centers through Remote Direct Memory Access (RDMA) over Ethernet. The key iWARP components that deliver 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 I/O data processing efficiency for data delivery and data consumption from I/O devices. With Intel DDIO, Intel® Server Adapters and controllers talk directly to the processor cache without a detour via system memory, reducing latency, increasing system I/O bandwidth, and reducing power consumption.

PCI-SIG* SR-IOV Capable
Single-Root I/O Virtualization (SR-IOV) involves natively sharing 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 to be multiple separate physical devices.

Flexible Port Partitioning
Flexible 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 virtual machine monitor (VMM) 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.
