Intel Ethernet Network Adapter E810-XXVDA4

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

Intel Data Direct I/O Technology
The Intel Data Direct I/O Technology is a platform technology that enhances the efficiency of I/O data processing for the transfer and utilization of I/O devices. With Intel DDIO, Intel server adapters and controllers communicate directly with the processor cache, bypassing the system memory, which reduces latency, increases the system's I/O bandwidth, and lowers power consumption.

PCI-SIG SR-IOV capable
Single-Root I/O Virtualization (SR-IOV) enables the native sharing of a single I/O resource among 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
The Flexible Port Partitioning (FPP) technology leverages the industry-standard PCI SIG SR-IOV standard to efficiently divide your physical Ethernet device into multiple virtual devices. This ensures quality of service by guaranteeing 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 designed to offload part of the switching performed in the Virtual Machine Monitor (VMM) to network hardware specifically designed for this purpose. VMDq drastically reduces the overhead associated with I/O switching in the VMM, significantly improving throughput and overall system performance.
