The BCM57710 provides a fully integrated Layer 4 and Layer 5
solution—TCP/IP, RDMA, and iSCSI 1.0 along with dual 1000/2500/
10GBASE-X Ethernet, IEEE 802.3-compliant media access control
(MAC), and physical layer transceiver solution for high-performance
network applications.
By itself, the BCM57710 provides a complete single-chip dual-channel
10GBASE-KX4/10GBASE-CX4 C-NIC with a TCP/IP, RDMA NIC
(RNIC), iSCSI 1.0 HBA functionality for NIC or LOM solution.
Interfacing to various 10-Gbps SerDes products from Broadcom, the
BCM57710 can be used in multiple application scenarios. Using
Broadcom BCM87XX devices, the XFI interface allows interface to
XFP modules. Various companion devices can be used for 10GBase-KR
or other copper interfaces.
The BCM57710 is a third-generation C-NIC and different from Layer-2
Ethernet network controllers. When transmitting, the BCM57710 can
access data posted in application buffers or other buffers and process the
TCP/IP, iSCSI, and RDMA layers, add the appropriate headers and
fields (e.g., CRC and markers), and transmit the data, thereby relieving
the host CPU from these time-consuming operations. On the receive
path, the BCM57710 processes the frame up to the highest layer present
for TCP, iSCSI, or RDMA strip headers, and special fields (e.g., CRC
and markers) and places the data with zero copy in the best buffer
available for the data—an application buffer, TCP level buffer, or a
generic buffer.
With the appropriate configuration, the BCM57710 can simultaneously
support the following functions:
• RDMA network interface controller (RNIC)
• iSCSI host bus adapter (HBA)
