Intel® Server Board S5000PAL / S5000XAL TPS Functional Architecture

3.4Network Interface Controller (NIC)

Network interface support is provided from the built in Dual GbE MAC features of the ESB-2 in conjunction with the Intel® 82563EB compact Physical Layer Transceiver (PHY). Together, they provide the server board with support for dual LAN ports designed for 10/100/1000 Mbps operation.

The 82563EB device is based upon proven PHY technology integrated into the Intel® Gigabit Ethernet Controllers. The physical layer circuitry provides a standard IEEE 802.3 Ethernet interface for 1000BASE- T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab). The 82563EB device is capable of transmitting and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps

Each Network Interface Controller (NIC) drives two LEDs located on each network interface connector. The link/activity LED (to the right of the connector) indicates network connection when on, and Transmit/Receive activity when blinking. The speed LED (to the left of the connector) indicates 1000- Mbps operation when amber, 100-Mbps operation when green, and 10-Mbps when off. The table below provides an overview of the LEDs.

3.4.1Intel® I/O Acceleration Technology

Intel® I/O Acceleration Technology moves network data more efficiently through Dual-Core Intel® Xeon® processor 5000 sequence-based servers for improved application responsiveness across diverse operating systems and virtualized environments. Intel® I/OAT improves network application responsiveness by unleashing the power of Dual-Core Intel® Xeon® processors 5000 sequence through more efficient network data movement and reduced system overhead. Intel multi-port network adapters with Intel® I/OAT provide high-performance I/O for server consolidation and virtualization via stateless network acceleration that seamlessly scales across multiple ports and virtual machines. Intel® I/OAT provides safe and flexible network acceleration through tight integration into popular operating systems & virtual machine monitors, avoiding the support risks of 3rd-party network stacks and preserving existing network requirements such as teaming and failover.

3.4.2MAC Address Definition

Each Intel® Server Board S5000PAL / S5000XAL has four MAC addresses assigned to it at the Intel factory. During the manufacturing process, each server board will have a white MAC address sticker placed on the board. The sticker will display the MAC address in both bar code and alpha numeric formats. The printed MAC address is assigned to NIC 1 on the server board. NIC 2 is assigned the NIC 1 MAC address + 1.

Two additional MAC addresses are assigned to the Baseboard Management Controller (BMC) embedded in the ESB-2. These MAC addresses are used by the BMC’s embedded network stack to enable IPMI remote management over LAN. BMC LAN Channel 1 is assigned the NIC1 MAC address + 2, and BMC LAN Channel 2 is assigned the NIC1 MAC address + 3.
