IWARP/RDMA

IWARP provides low-latency converged fabric services for data centers with 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 data delivery and data use of I/O devices. With Intel data-direct I/O technology, the Intel® server adapters communicate directly with the processor cache without having to go through system memory, WAS reduces latency, increases system I/O bandwidth, and reduces power consumption.


Suitable for PCI-SIG* SR-IOV

Single root I/O virtualization involves the native (direct) sharing of a single I/O resource between multiple virtual machines. Single root I/O virtualization provides a mechanism to represent a single root function (for example, a single Ethernet port) as multiple separate physical devices.


Flexible Port Partitioning

Flexible port partitioning technology leverages 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 portion of bandwidth.


Virtual Machine Device Queues (VMDq)

Virtual Machine Device Queues is a technique designed specifically for offloading some switching operations in the virtual machine monitor to network hardware. Virtual machine device queues dramatically reduce operating costs associated with I/O switching within the virtual machine monitor, WAS significantly increases throughput and overall system performance.
