ETHERNET CONTROLLER
FEATURES
SUMMARY OF BENEFITS
• 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
