The BCM57810S is a sixth-generation Converged 
Controller designed for high-volume, converged LAN on 
motherboard (LOM) and converged network adapter 
applications, enables PCI SIG Single Root I/O 
Virtualization (SR-IOV), iSCSI, FCoE, DCB, on-chip TOE, 
and RDMA. The Converged Controller supports PCIe™ 
3.0 along with Embedded Virtual Bridging and other 
switching technologies for high-performance direct 
memory access (DMA) and virtual machine (VM) to VM 
switching.

The BCM57810S includes dual-channel 10GBASE-KR and 
SFF-8431 for SFP+ 10 Gb interfaces. The BCM57810S 
integrates two IEEE 802.3™-compliant Media Access 
Controllers (MAC) and supports the NC-SI. Host-BMC 
communication is also supported on top of NC-SI to 
permit high-speed communication between the local 
host and the Baseboard Management Controller (BMC or 
MC). The feature-complete Converged Controller 
requires only 0.82 square inches of PCB space and 
enables 10G speeds at low per port power.

The BCM57810S enables convergence of all the possible 
network communications in a server, such as data 
network (LAN), FCoE storage network, block, for 
example, iSCSI, or file, for example, CIFS/NFS, clustering 
or Interprocess Communications (IPC) by support of 
RDMA over TCP. The BCM57810S can simultaneously 
support all offload traffic types on each of the ports, 
including simultaneous iSCSI and FCoE. Offload results in 
superior storage and networking performance, and low 
CPU utilization, resulting in significant system level 
power savings.

The BCM57810S is designed for PCIe 3.0 and is also com-
patible with PCI Express® (PCIe) Base Specification Revi-
sions 2.0 and 1.1. The PCI Express supports MSI and MSI-
X capabilities. A separate PCI function is supported for 
each of the ports.
