The IBM NetXtreme 1000 T Dual Ethernet Adapter enables high-performance network connections for the IBM eServer xSeries. Server performance is optimized to ensure that system I/O is not a bottleneck in high-performance networking applications. The NetXtreme 1000 T Dual Port Ethernet Adapter (31P6401) comes with three key improvements over the earlier IBM Dual Port Ethernet Adapter option (22P4901): first Dual Port PCI-X 10/100/1000 Ethernet Adapter offering based on the latest Broadcom BCM5704 technology for xSeries; Dual Port option provides dual Ethernet ports at up to 64-bit/133 MHz PCI-X performance in a single PCI/PCI-X slot to free up other slots in the system; hardware/software commonality with xSeries BCM570x on-board and adapter technologies Industry-Leading Performance.The NetXtreme 1000 T Dual Port Ethernet Adapter uses a BCM5704 chip, the latest in gigabit Ethernet technology from Broadcom. Flexible architecture, which matches the hardware behavior to the operating system, allows higher data throughput and increased CPU performance. Higher data throughput offers better utilization of the entire network and contributes to lower latencies for the applications. Lower CPU utilization enables the server to execute applications faster when communicating over the network. Adapter Fault Tolerance and load balancing options from a single adapter and PCI bus slot deliver optimal system reliability and throughput with efficient, minimal resource utilization. The NetXtreme 1000 T Dual Port Ethernet Adapter comes with full smart load balance and failover options for fault tolerance and optimized bandwidth. It includes 802.3ad teaming, GEC trunking teaming, and VLAN (802.1Q) option for traffic segregation and data privacy.
