The 82580 is a single-chip low-power device that can provide significant BOM savings by reducing the support components (bridge chips, crystals, and EEPROMS) required when compared with dual-port or multiple single-port GbE designs. The Intel® 82580 provides fully integrated Gigabit Ethernet Media Access Control (MAC), Physical-Layer (PHY), Serializer- Deserializer (SERDES), and SGMII interface capabilities. The Intel® 82580 supports the MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, 10BASE-T connections (802.3, 802.3u, 802.3ab), the SERDES inter- face for 1000Base-SX/LX optical fiber connections, the 1000BASE-KX and 1000BASE-BX for backplane connections, and supports the SGMII interface for SFP/external PHY con- nections. Performance Benefits for Demanding Applications The Intel® 82580 Gigabit Ethernet Controller supports Intel® I/O Acceleration Technology (I/OAT) and also contains eight transmit and eight receive queues. The Intel® 82580 efficiently manages packets with minimum latency by combining parallel and pipelined logic architectures that are optimized for these independent Tx and Rx queues. These queues, combined with Receive Side Scaling (RSS), Direct Cache Access, and Message Signal Interrupt Extension (MSI-X) support, provide performance optimization benefits for multi-core designs. The Intel® 82580 provides advanced interrupt-handling features, and provides intelligent filtering, ordering and directing of packets to specific queues and cores to enable load-balancing of network traffic flows. Other performance-enhancing features include UDP, TCP and IP Checksum offloads, UDP and TCP Transmit Segmentation Offload (TSO), SCTP receive and transmit checksum offloads, Stateless offloads (header splitting), and 9500-byte jumbo frame support. For the virtualized environment, the Intel® 82580 supports Intel® 1 for Connectivity (VT-c) and Virtual Virtualization Technology Machine Data queue, (VMDq), which improve I/O performance by reducing the I/O overhead on a virtualized platform. The Intel® 82580 supports up to 8 Virtual Machines per port (a queue is allocated to each VM). On-Board Side-Band Interfaces for Network Manageability The Intel® 82580 Gigabit Ethernet Controller contains an SMBus port and DMTF-defined Network Controller Sideband Interface (NC-SI) for manageability. Ethernet traffic is forwarded from the network to the baseboard management controller (BMC) and vice versa using the selected implementation. The Intel® 82580 provides filtering capabilities to determine which traffic is forwarded to the BMC. SMBus provides a legacy low-speed (100KHz) serial bus to pass network traffic and also Read the full Product Brief Intel® 82580 Gigabit Ethernet Controller Network Connectivity.
