BCM5720 Gigabit Ethernet: Energy Efficient Ethernet support, hardware support for IEEE 1588 timestamping, host to connection for better system manageability.Designed for today's enterprise and data center environments, Broadcom's NetXtreme 1G Ethernet controllers are the ideal solution for multi-core servers, delivering full line-rate throughput on all ports.PCIe 2.1 1x Port 1G LAN BCM5720 Ethernet Controller is a 13th generation 10/100/1000BASE-T and 10/100/1000BASE-X Ethernet LAN controller solution for high performance server and networking applications.The host interface supports separate PCI functions for each LAN interface. The BCM5720 includes I/O Virtualization (IOV) functions such as 17 receive and 16 transmit queues, and 17 -X vectors with flexible vector-to-queue association.These IOV capabilities enable the BCM5720 to support VMWare NetQueue and VMQ technologiesIntegrated 10/100/1000BASE-T and 1000BASE-X/SGMII 1.25 Gbaud SerDes transceivers.Energy Efficient Ethernet (EEE) compliant with IEEE Std 802.3az 2010 10/100/1000BASE-T full/half duplex 1000BASE-X/SGMII Full/Half Duplex Automatic MDI Crossoverx2 PCI v2.0 at 5 GT/s or 2.5 GT/s and -X capabilities - up to 17 -X vectorsI/O Virtualization (IOV) support for VMWare NetQueue and VMQ17 receive queues and 16 transmit queues17 -X vectors support interrupt to host per queueFlexible -X vector for send/receive queue associationTLP Processing (TPH) ECN Compliant with PCI Base Specification v2.0Supports jumbo frames with payloads up to 9600 bytesVirtual LAN (VLAN) support - IEEE 802.1q VLAN taggingTCP, IP, UDP checksum offload Send Offload (LSO), TCP Segmentation Offload ()Hardware-Assisted Implementation of IEEE 1588 and IEEE 802.1AS Time SynchronizationIEEE 802.3x flow controlOn-chip temperature monitorPCI CLKREQ support Management Offload (PM Offload)Serial Flash and EEPROM NVRAM support; Flash auto-configurationECC Error Detection and Correction on Internal SRAMMaterial: PCBcolour: greenPackage Contents:1 x Network Card1 x Driver-CD1 x Short Iron PieceOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
