bcm57711 Broadcom Corp., bcm57711 Datasheet - Page 2

• Manufacturer Part Number: bcm57711
• Description: 10-gbps Dual-port Tcp, Iscsi, Rdma Controller With X8 Lane Pci Express Ver. 2.0
• Manufacturer: Broadcom Corp.

The BCM57711 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 for high-performance network
applications.
By itself, the BCM57711 provides a complete single-chip dual-channel
10GBASE-KX4/10GBASE-CX4 C-NIC with a TCP/IP, RDMA NIC
(RNIC), and iSCSI 1.0 HBA functionality for NIC or LOM solutions.
Interfacing to various 10 Gbps SerDes products from Broadcom, the
BCM57711 can be used in multiple application scenarios. Using
Broadcom BCM87XX devices, the XFI interface allows interfacing to
XFP modules. Various companion devices can be used for
10GBASE-KR or other copper interfaces.
The BCM57711 is a third-generation C-NIC and different from Layer-2
Ethernet network controllers. When transmitting, the BCM57711 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 BCM57711 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 BCM57711 can simultaneously
support the following functions:
• RDMA network interface controller (RNIC)
• iSCSI host bus adapter (HBA)
