SUMMARY OF BENEFITS

• Industry’s smallest 10/100/1000 MAC+PHY solution—power

and space optimized for LOM and low-profile NIC

applications

• Completely backward-compatible:

• To existing 10/100 network infrastructure

• To existing PCI-based desktop and server platforms

• Futureproof

• PCI-X interface, on-chip programmable CPUs, ASF support

• Performance focused—optimized for throughput and CPU

utilization

• Adaptive interrupts

• PCI-X eliminates PCI bottlenecks

• Ultra-deep 96-KB packet buffer lowers CPU utilization and

avoids PCI congestion

• CPU task offloads reduces utilization level of CPU

• Robust and highly manageable

• PXE 2.0, ACPI 1.1a, Wake on LAN, ASF 1.0, IPMI

• Integrated cable testing—link quality, length, pair skew, pair

polarity, pair swap

• Advanced features

• VLAN, priority queuing, jumbo frames

• RISC processors for advanced packet classification

• Server class reliability, availability, and performance features

• Link aggregation and load balancing

• Switch-dependent
