Intel? Ethernet Server Adapter I210 Single-Port Gigabit Ethernet server adapter designed for entry-level servers and Audio-Video applications. Overview The new Intel? Ethernet Server Adapter I210 builds on Intel’s history of excellence in Ethernet products. Intel continues its market leadership with this newest gen- eration PCIe* GbE network adapter. Based on the Intel? Ethernet Controller I210, this adapter represents the next step in the Gigabit Ethernet (GbE) networking evolu- tion for the enterprise and data center offering Audio-Video-Bridging (AVB) sup- port, along with power management tech- nologies such as Energy Efficient Ethernet (EEE) and DMA Coalescing (DMAC). Audio-Video Bridging (AVB) The Intel? Ethernet Server Adapter I210 supports IEEE 802.1Qav Audio-Video Bridging (AVB) for customers requiring tightly controlled media stream synchro- nization, buffering, and reservation. The 802.1Qav is part of the AVB specification that provides a way to guarantee bounded latency and latency variation for time sensitive traffic and includes: ? Timing and Synchronization for time- specific applications (802.1AS) Stream Reservation (SR) protocol to guarantee the resources needed for Audio/Video (AV) streams (802.1Qat) ? Forwarding and queueing enhancements for time sensitive streams (802.1Qav). Performance Optimization The Intel? Ethernet Server Adapter I210 contains four transmit and four receive queues. These queues offer Error Correct- ing Memory (ECC) protection for improved data reliability. The adapter efficiently manages packets with minimum latency by combining parallel and pipelined logic architectures optimized for these inde- pendent transmit and receive queues. These queues, combined with Receive Side Scaling (RSS) and Message Signal Interrupt Extension (MSI-X) support, optimize the performance on servers with multi-core processors. KEY FEATURES ?
