Intel today announced two new Ethernet controllers that facilitate high traffic flow and optimize I/O performance in such enterprise server environments as multicore Intel Xeon processor-based systems and virtualized datacenters.

The Intel 82598 and Intel 82575 Ethernet controllers distribute workloads across all available processing cores to reduce utilization and achieve optimal system performance.

The Intel 82598 10 Gigabit Ethernet Controller provides dual-port, PCI Express-based 10GbE connectivity to handle high-speed interconnects. This product addresses the networking bottlenecks associated with server consolidation and is ideal for virtualization and such demanding enterprise applications as storage and high performance computing.

The Intel 82575 Gigabit Ethernet Controller offers many of the same features at 1GbE connectivity. This new dual-port controller, which provides virtualization optimizations, is designed for use in Intel's next-generation low-profile, quad-port server adapters.

The Intel 82598 10 Gigabit Ethernet Controller provides dual-port 10GbE at an average of just 4.8 watts.

The controllers also support Intel I/O Acceleration Technology (Intel I/OAT), which increases I/O throughput and reduces CPU utilization in multicore Intel processor-based servers.

The Intel 82575 Gigabit Ethernet Controller is available now, and the Intel 82598 10 Gigabit Ethernet Controller will be available for volume shipment in September.
