Intel ® Ethernet network adapter E810-CQDA2

IWARP offers converged fabric services with low latency for data centers using Remote Direct Memory Access (RDMA) over Ethernet. The key components of iWARP that contribute to low latency include Kernel Bypass, Direct Data Placement, and Transport Acceleration.

The Intel Data Direct I/O technology is a platform technology designed to improve the efficiency of I/O data processing for data delivery and utilization from I/O devices. With Intel Data Direct I/O technology, Intel server adapters communicate directly with the processor cache, bypassing system memory, which reduces latency, increases system I/O bandwidth, and lowers energy consumption.

Single Root I/O Virtualization involves the native (direct) sharing of a single I/O resource among multiple virtual machines. This virtualization provides a mechanism through which a single root function (for example, a single Ethernet port) can be represented as multiple separate physical devices.

The Flexible Port Partitioning technique utilizes the industry-standard PCI SIG SR-IOV to efficiently partition the physical Ethernet device into multiple virtual devices and offers Quality of Service by ensuring that each process is assigned to a virtual function and receives an appropriate share of the bandwidth.

Virtual Machine Device Queues is a technique for offloading some switching operations in the virtual machine monitor to network hardware specifically designed for this function. This technique drastically reduces the operating costs associated with I/O switching within the virtual machine monitor, significantly increasing throughput and overall system performance.
