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 contribute to low latency include 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 designed to enhance the efficiency of I/O data processing for the provisioning and utilization of 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.

Compatible with 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 through 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 technique utilizes the industry-standard PCI SIG SR-IOV to efficiently partition the physical Ethernet device into multiple virtual devices, offering 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 from the virtual machine monitor to network hardware specifically designed for this function. Virtual Machine Device Queues significantly reduce the operational costs associated with I/O switching within the virtual machine monitor, thereby greatly enhancing throughput and overall system performance.
