Launch Date

The date the product was first introduced.

Flexible Port Partitioning

Flexible Port Partitioning (FPP) technology utilizes industry standard PCI SIG SR-IOV to efficiently divide your physical Ethernet device into multiple virtual devices, providing Quality of Service by ensuring each process is assigned to a Virtual Function and is provided a fair share of the bandwidth.

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


Single-Root I/O Virtualization (SR-IOV) involves natively (directly) sharing a single I/O resource between multiple virtual machines. SR-IOV provides a mechanism by which a Single Root Function (for example a single Ethernet Port) can appear to be multiple separate physical devices.


iWARP delivers converged, low-latency fabric services to data centers through Remote Direct Memory Access (RDMA) over Ethernet. The key iWARP components that deliver low-latency are Kernel Bypass, Direct Data Placement, and Transport Acceleration.


RoCEv2/RDMA (Remote Direct Memory Access over Converged Ethernet v2) delivers converged, low-latency fabric services to data centers through RDMA over UDP/IP. UDP/IP (User Datagram Protocol) is a communication protocol used for time-sensitive transmissions such as video or voice that speeds up communications by not requiring a “handshake” from the receiving party.

Intel® Data Direct I/O Technology

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.
