optimized for server blade and low-profile NIC applications.
Extremely low CPU utilization for TCP/IP applications
• Host CPU is free to run application code
• Easy integration with Microsoft’s TOE Chimney Architecture
Accelerated IP-based storage
• Lower CPU utilization for file-level storage protocols such as
CIFS and NFS
• iSCSI functionality with low CPU utilization
RDMA support for data placement in application buffers
reduces CPU utilization and lowers data transit latencies.
Future-proof
• Flexible implementation for TCP, iWARP and iSCSI can
accommodate specification changes and interoperability
issues.
Performance-focused – optimized for throughput and CPU
utilization
• Adaptive interrupts
• RSS reduces CPU utilization on multi-CPU systems.
• MSI allows interrupt distribution in a multi-CPU host system.
• PCI-Express host interface allows a low-latency access to CPU
and Memory resources.
Robust and highly manageable
• UMP enables high bandwidth "out-of-band" system
management functionality over shared infrastructure.
• PXE 2.0, ACPI 1.1, Wake-On LAN, ASF 1.0.
• IPMI 'pass-through' capability allows on-board management
controllers access to the network in OS-present and OS-absent
states.
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
Low power for zero airflow implementations
• Advanced power management
Minimal real estate—ideal for LOM
• On-chip power circuit controller

The BCM5708C provides a fully integrated Layer 4 and Layer 5
solution - TCP/IP, RDMA and iSCSI 1.0/iSER along with a complete 10/
100/1000BASE-T Gigabit Ethernet, IEEE 802.3 compliant Media
Access Control (MAC) and Physical Layer Transceiver solution for high
performance network applications. By itself, the BCM5708C provides a
complete single-chip Gigabit Ethernet NIC with a TCP/IP Offload
Engine, RDMA NIC (RNIC), iSCSI 1.0/iSER HBA or LOM solution.
The BCM5708C is different from other network controllers because it
can process the TCP/IP and relevant L5 protocols on data directly from
the application buffers on the host, therefore relieving the host CPU from
these time-consuming operations. On the receive path, the BCM5708C
processes the frame up to the highest layer supported present in it, e.g.,
the BCM5708C processes the frame for RDMA when the frame is an
RDMA frame.
