Intel Ethernet Server Adapter I210

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.

Power Management Technologies

Today, companies everywhere are looking for ways to decrease energy consumption across the enterprise to reduce costs and environmental impact, while at the same time solving increasingly important power density challenges. That's why Intel has introduced new, advanced Power Man-agement Technologies (PMTs that enable enterprises to configure power options on the adapter and more effectively manage power consumption.

Energy Efficient Ethernet (EEE)

The Intel Ethernet Server Adapter I210 family supports the IEEE802.3az Energy Efficient Ethernet (EEE) standard so that, during periods of low network activity, EEE reduces the power consumption of an Ethernet connection by negotiating with a compliant EEE switch port to transition to a low power idle (LPI) state.

This reduces the controller power to ap-proximately 50% of its normal operating power, saving power on the network port and the switch port. When increased net-work traffic is detected, the controller and the switch quickly come back to full power to handle the increased network traffic. EEE is supported for both 1000BASE-T and 100BASE-TX.

DMA Coalescing

Another power management technology that can reduce power on the server plat-form is DMA Coalescing (DMAC). Typically, when a packet arrives at the adapter, a DMA request is initiated in order to place the packet into host (or server) memory. This transaction wakes up the processor, memory, and other system components from a lower power state in order to perform the tasks required to handle the incoming packet.
