JTAG
Industry’s smallest 10/100/1000BASE-T solution –
power and space optimized for LOM and low profile
NIC applications.
Extremely low CPU utilization for TCP/IP applications
Host CPU is freed to run application code
Enables lower performance host CPU to drive 1-Gbps TCP
traffic
Support for file and block storage systems
Provides TCP Offload for File Storage (e.g., CIFS and NFS)
and iSCSI for block oriented storage
Completely backward compatible to existing 10/100
network infrastructure
Future-proof
Flexible firmware based implementation for TCP and iSCSI,
protects the BCM5706 from specification changes and
interoperability issues
PCI-X interface, on-chip programmable CPUs
Performance-focused – optimized for throughput and
CPU utilization
Adaptive interrupts
PCI-X – eliminates PCI bottlenecks
Robust and highly manageable
PXE 2.0, ACPI 1.1, Wake-On LAN, ASF 1.0
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
802.3ad (LACP), generic trunking (GEC/FEC)
- Switch and NIC independent
PCI hot plug
Low power for zero airflow implementations
