Lenovo ThinkSystem NetXtreme PCIe 1Gb 4-Port RJ45 Ethernet Adapter By Broadcom

The NetXtreme Quad Port Ethernet Adapter is an ideal way to implement a virtualization solution using your existing Gigabit Ethernet network. With four copper-based Gigabit ports on a single PCI Express 2.0 x4 interface, the adapter provides the density and capacity you need to support large numbers of virtualized systems on one server.

The adapters have the following features:
•One, two, or four 10/100/1000 copper ports with RJ45 for Cat 5e/6 cabling
•Full line-rate performance across all ports
•Low-profile form factor - supported by the majority of System x and iDataPlex servers
•PCI Express 2.0 host interface (39Y6066 is PCI Express 1.1)
•Jumbo Frames support (9600 bytes frames)
•IEEE 802.1q VLAN support - provides enhanced network management and efficiency
•I/O virtualization (IOV) support for VMWare NetQueue and Microsoft VMQ - improves network performance in virtualized environments
•IEEE 802.3x flow control support
•Receive and transmit side scaling
•TCP, IP, and UDP checksum offload
•Message Signaled Interrupts (MSI) and MSI-X support - Maximizes server processing performance by reducing CPU overhead and lowering interrupt latency
•On-chip temperature monitor (NetXteme I only)
•IEEE 802.3az Energy Efficient Ethernet (EEE) compliant - Reduces adapter power consumption by up to 42% through intelligent adaptive power management, adjusting power based on data traffic load. (NetXtreme I only)
•IEEE 802.3z (Clause 30) - Statistics for SNMP MIB II, Ethernet like MIB, and Ethernet MIB (NetXtreme I only)
•IEEE 1588 Precision Time Control and 802.1AS time synchronization support - Provides greater accuracy of data packet delivery within the network (NetXtreme I only)
•Management using Broadcom Advanced Control Suite (BACS), Windows Management Instrumentation (WMI), and Broadcom Management API (BMAPI)
