Network Interface Card (NIC) applications Integrated 10BASE-T/100BASE-TX/1000BASE-T transceivers Host interfaces PCI-Expressx4 Host interface offload engine Full "fast Path" offload Compliant with Microsoft's Chimney Architecture iSCSI controller iSCSI initiator iSER (iSCSI over RDMA) RDMA controller (RNIC) RDMA over (iWARP)-RDMAC compliant Hardware-based data placement application buffers without intervention (User Kernel modes) Other performance features Receive Side Scaling (RSS) TCP, checksum segmentation Adaptive interrupts Message Signal Interrupt (MSI) support Robust manageability Universal Management Port (UMP) remote boot Alert Standard Format (ASF v1.0) support Wake-On IPMI 'pass-through' feature Statistics gathering (SNMP Ethernet-like MIB, Ethernet (802.3x, clause 30)) Comprehensive diagnostic configuration software suite ACPI 1.1a compliant power management Advanced network features Virtual LANs-802.1q VLAN tagging Jumbo frames 802.3x flow control Low-power CMOS design On-chip power circuit controller 400-ball 21x21 FBGA package 3.3V I/Os JTAG
SUMMARY BENEFITS Industry's first 10/100/1000 solution-power space
optimized server blade low-profile applications. Extremely utilization TCP/IP applications Host free application code Easy integration with Microsoft's Chimney Architecture Accelerated IP-based storage Lower utilization file-level storage protocols such CIFS iSCSI functionality with utilization RDMA support data placement application buffers reduces utilization lowers data transit latencies. Future-proof Flexible implementation TCP, iWARP iSCSI accommodate specification changes interoperability issues. Performance-focused optimized throughput utilization Adaptive interrupts reduces utilization multi-CPU systems. allows interrupt distribution multi-CPU host system. PCI-Express host interface allows low-latency access Memory resources. Robust highly manageable enables high bandwidth "out-of-band" system management functionality over shared infrastructure. 2.0, ACPI 1.1, Wake-On LAN, 1.0. IPMI 'pass-through' capability allows on-board management controllers access network OS-present OS-absent states. Server class reliability, availability, performance features Link aggregation load balancing Switch-dependent 802.3ad (LACP), generic trunking (GEC/FEC) Switch independent power zero airflow implementations Advanced power management Minimal real estate-ideal On-chip power circuit controller

Interface Interface
BCM5708C provides fully integrated Layer Layer solution TCP/IP, RDMA iSCSI 1.0/iSER along with complete 100/1000BASE-T Gigabit Ethernet, IEEE 802.3 compliant Media Access Control (MAC) Physical Layer Transceiver solution high performance network applications. itself, BCM5708C provides complete single-chip Gigabit Ethernet with TCP/IP Offload Engine, RDMA (RNIC), iSCSI 1.0/iSER solution. BCM5708C different from other network controllers because process TCP/IP relevant protocols data directly from application buffers host, therefore relieving host from these time-consuming operations. receive path, BCM5708C processes frame highest layer supported present e.g., BCM5708C processes frame RDMA when frame RDMA frame. With appropriate configuration, BCM5708C simultaneously support following three functions: RDMA Network Interface Controller (RNIC) iSCSI iSER Host Adapter Chimney-enabled network accelerator
