JL82598 Datasheet | Intel

features and energy-efficient design that meets the throughput and latency requirement of bandwidth-hungry applications. The 82598 controller is designed for multi-core processors and implements advanced features for efficient routing of packets using multiple queues as well as include load balancing of interrupts using MSI-X. The controller also supports stateless offloads such as TCP segmentation offload, header replications/splitting, and Direct Cache Access (DCA) to lower CPU utilization. In addition, the 82598 controller offers advanced features for Virtualization and Storage over Ethernet all within a very low power envelop of 4.8W (dual port). High-Performance Design Features The Intel 82598 10 Gigabit Ethernet Controller is a single, pact ponent with two fully integrated 10 Gigabit Ethernet Media Access Control (MAC) and XAUI ports. The controller supports CX4 (802.3ak- ) and KX4/KX (802.3ap- ) interfaces and each port contains a Serializer-Deserializer (Ser Des) for backward patibility with gigabit backplanes. The device is designed for high performance and lower memory latency. Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and data words. The controller includes advanced interrupt-handling features and uses efficient ring-buffer descriptor data structures, with up to 64 packet descriptors cached on chip. A large on-chip packet buffer maintains superior performance. The 82598 controller enables network manageability implementations required by IT personnel for remote control and alerting. The munication to the Board Management Controller (BMC) is available either through an on-board System...
