System x Broadcom NetXtreme I Dual Port GbE Adapter

The Broadcom NetXtreme Gigabit Ethernet Adapters are a family of high performance PCI Express adapters. With five adapters to choose from, the NetXtreme I and NetXtreme II adapter family offers a variety of features including up to four ports per adapter, VLAN support, broad operating system support, TOE, iSCSI, and virtualization support.
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 (NetXtreme II single-port 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)
