Marketing description

Intel Data Direct I/O technology is a platform technology that improves I/O data processing efficiency for data delivery and data consumption from I/O devices. With Intel DDIO, Intel server adapters and controllers talk directly to the processor cache without a detour via system memory, reducing latency, increasing system I/O bandwidth, and reducing power consumption.

Key selling points

• Flexible Port Partitioning
• Virtual Machine Device Queues (VMDq)
• iWARP/RDMA

Product features

• Virtual Machine Device Queues (VMDq)
  Virtual Machine Device Queues (VMDq) is a technology designed to offload some of the switching done in the VMM (virtual machine monitor) to networking hardware specifically designed for this function. VMDq drastically reduces overhead associated with I/O switching in the VMM which greatly improves throughput and overall system performance.
• iWARP/RDMA
  iWARP delivers converged, low-latency fabric services to data centers through Remote Direct Memory Access (RDMA) over Ethernet.
