BCM5706

Industry’s smallest 10/100/1000 TOE solution—power and

space optimized for LOM 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

• iSCSI functionality with low CPU utilization

RDMA support for data placement in application buffers

reduces CPU utilization and lowers data transit latencies. The

result is improved application performance and faster user

response time.

• Broadcom’s Gigabit controller family – BCM570x

• Existing Ethernet 10/100/1000 network infrastructure

Future-proof

• Flexible implementation for TCP, iWARP and iSCSI can

Performance-focused – optimized for throughput and CPU

utilization

• Adaptive interrupts

• MSI allows interrupt distribution in a multi-CPU host system

• Support for PCI-X—allows sufficient bandwidth for wire

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

• IPMI 'pass-through' capability allows on-board management

Server class reliability, availability and performance features

• Link aggregation and load balancing

• 802.3ad (LACP), generic trunking (GEC/FEC)

• PCI hot plug

Low power for zero airflow implementations

• Advanced power management

Minimal real estate—ideal for LOM

• On-chip power circuit controller

Interoperable with:

CIFS and NFS

accommodate specification changes and interoperability issues

speed operation

polarity, pair swap

controllers access to the network in OS-present and OS-absent

states

- Switch-dependent

- Switch and NIC independent
