BCM957454M4540C

Single-Port 1/10/25/40/50/100 Gb/s Ethernet PCI Express Gen3 x16 OCP

Mezzanine Card

Overview

The Broadcom BCM957454M4540C is a single-port 1/10/

25/40/50/100 Gb/s adapter designed to the Open Compute

Project (OCP) mezzanine card specification with a QSFP28

network connector. The adapter is designed to the OCP

Mezzanine v2.0 specification as a Type 1 adapter with the

board outline adhering to the original v0.5 dimensions. The

adapter supports both QSFP28/QSFP+ optical modules

and copper direct-attach cables.



Features



Single-port pluggable media interface, which may be

equipped with 100 Gb/s or 40 Gb/s QSFP28/QSFP+

optical transceiver or with copper direct-attach cable.

Fully compliant with the SFF-8665 standard.

16-lane PCI Express host interface that is designed to

operate to the PCI Express v3.0 specifications. Support

for up to four external hosts (for example, it has four

PCIe endpoints) multiplexed through the Multi-Host

Bridge (MHB).

SR-IOV with up to 1K virtual functions (VFs).

Function-Level Reset (FLR) support.

TruFlow™ flow processing engine.

Virtual Network Termination-VXLAN, NVGRE, Geneve,

GRE encap/decap.

vSwitch acceleration.

Tunnel-aware stateless offloads.

DCB support: PFC, ETS, QCN, DCBx.

TruManage™ integrated BMC.

Network Controller Sideband Interface (NC-SI).

SMBus 2.0.

MCTP over SMBus.

PCIe-based UART and KCS.

Jumbo frames up to 9 KB.

Advanced Congestion Avoidance.

Multiqueue, NetQueue, and VMQ.

IPv4 and IPv6 offloads.

TCP, UDP, and IP checksum offloads.



Large Send Offload (LSO).

Large Receive Offload (LRO).

TCP Segmentation Offload (TSO).

Receive-side Scaling (RSS).

Transmit-side Scaling (TSS).

VLAN insertion/removal.

Interrupt coalescing.

Network boot – PXE, UEFI.

iSCSI boot.

Wake-on-LAN (WOL).

MSI and MSI.X.

Conforms to the OCP Mezzanine Card Design

Specification v2.0 Type 1.

Single-port 1/10/25/40/50/100-Gigabit Ethernet adapter

for Open Compute Platform systems.
