Intel E810XXVDA2OCP3G 25GbE Ethernet Network Adapter E810

IWARP/RDMA

iWARP provides converged fabric services with low latency for data centers using Remote Direct Memory Access (RDMA) over Ethernet. The key components of iWARP 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 the delivery and use of data by I/O devices. With Intel Data Direct I/O technology, Intel server adapters communicate directly with the processor cache without detouring through system memory, reducing latency, increasing the system's I/O bandwidth, and lowering power consumption.

Suitable for PCI-SIG SR-IOV

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

Flexible Port Partitioning

The flexible port partitioning technology utilizes the industry-standard PCI-SIG SR-IOV to efficiently divide the physical Ethernet device into multiple virtual devices and provides 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 (VMDq)

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. Virtual Machine Device Queues drastically reduce the operating costs associated with I/O switching within the virtual machine monitor, significantly increasing throughput and overall system performance.
