Powerful, feature-rich NetXtreme Dual-Port 1G PCIe Ethernet NIC. Number of Ports: 2. Interface Speed: 10/100/1000 Mbps. Connection Type: PCI-Express x1. Full-Height, Low-Profile. Energy-efficient Ethernet according to IEEE Std 802.3az-2010, IEEE 802.3ap Clause 73 Auto-Negotiation. Two 10/100/1000BASE-T full-duplex/half-duplex MACs, virtualization support with VMware NetQueue and Microsoft VMQ, Wake-on-LAN support. Broadcom's NetXtreme 1G Ethernet adapters are designed for today's enterprise and data center environments and are the ideal solution for multicore servers, providing full line-rate throughput across all ports. The BCM5720 PCIe NIC is a 10/100/1000BASE-T and 10/100/1000BASE-X Ethernet LAN controller of the 13th generation for high-performance server and networking applications. The host interface supports a separate PCI Express function for each LAN interface. The BCM5720 features I/O virtualization capabilities (IOV) such as 17 receive and 16 transmit queues and 17 MSI-X vectors with flexible vector-to-queue mapping. These IOV features enable the BCM5720 to support VMware NetQueue and Microsoft VMQ technologies. The BCM5720 includes extensive hardware features that allow the system to implement IEEE 1588 or IEEE 802.1AS-based time synchronization. These hardware features include a high-precision clock, timestamp registers for received/sent packets, as well as programmable trigger inputs and watchdog outputs.
