1 / 2 page BCM5706 ® 10/100/1000BASE-T TCP OFFLOAD ENGINE, RDMA, ISCSI/ISER AND ETHERNET CONTROLLER • Single-chip solution for LAN on Motherboard (LOM) and Network Interface Card (NIC) applications • Integrated 10BASE-T/100BASE-TX/1000BASE-T transceivers • Integrated SerDes (BCM5706S) • Host interfaces - PCI v2.3—32/64 bits, 33/66 MHz - PCI-X v1.0—64 bits, 66/100/133 MHz • TCP offload engine • Full “fast Path” TCP offload • Designed for Microsoft’s TOE Chimney Architecture • iSCSI controller • iSCSI initiator • iSER (iSCSI over RDMA) • RDMA controller (RNIC) • RDMA over TCP (iWARP)—RDMAC 1.0 compliant • Hardware-based data placement in application buffers without CPU intervention (for User and Kernel modes) • Other performance features • TCP, IP checksum • TCP segmentation • Adaptive interrupts • Message Signal Interrupt (MSI) support • Robust manageability • PXE 2.0 remote boot • Alert Standard Format (ASF v1.0) support • Wake-On LAN • IPMI 'pass-through' mode • Statistic gathering (SNMP MIB II, Ethernet like MIB, Ethernet MIB (802.3x, clause 30)) • Comprehensive diagnostic and configuration software suite • ACPI 1.1a compliant—power management • Advanced network features • Virtual LANs—802.1q VLAN tagging • Jumbo frames (9 KB) • 802.3x flow control • Low-power CMOS design • On-chip power circuit controller • 400-ball 21x21 mm FBGA package • 3.3V I/Os • JTAG • 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 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. The result is improved application performance and faster user response time. • Interoperable with: • Broadcom’s Gigabit controller family – BCM570x • Existing Ethernet 10/100/1000 network infrastructure • 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 • MSI allows interrupt distribution in a multi-CPU host system • Support for PCI-X—allows sufficient bandwidth for wire speed operation • 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 • 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 • PCI hot plug • Low power for zero airflow implementations • Advanced power management • Minimal real estate—ideal for LOM • On-chip power circuit controller FE A T UR E S SU MM AR Y O F B E N E FI TS |
