Introduction
The ThinkSystem Broadcom 57454 10/25GbE SFP28 Ethernet Adapters are high-performance 25 Gb Ethernet adapters in either standard PCIe form factor or the Open Compute Project (OCP) 3.0 SFF form factor. They offer TruFlow™ intelligent flow processing and supports advanced networking technologies including RoCE v2, SDN, NFV and virtualization.
The following figure shows the 4-port OCP adapter.

Did you know?
These adapters support 10 Gb or 25 Gb Ethernet switches, including the ThinkSystem NE2572 RackSwitch 25 Gb Ethernet switch. Alternatively, with suitable breakout cables, you can connect four 25 Gb adapters or ports to a single 100 GbE switch port such as the ThinkSystem NE10032 RackSwitch to maximize the investment of your 100Gb switch.
Part number information
The ordering information is listed in the following table.
* The V2 adapter, 4XC7A08316, offers improved electrostatic discharge (ESD) support over the existing adapter, 4XC7A08241; No functional change.
The adapters, when shipped as a stand-alone option part number, includes the following items:
- One Broadcom adapter
- PCIe adapters: Full-height (3U) bracket attached with low-profile (2U) bracket included in the box
- Documentation flyer
Supported transceivers and cables
The adapters have empty SFP28 cages for connectivity. The adapters either support a connection to a 10 Gb or 25 Gb switch or can share a connection to a 100 Gb switch using a 4:1 breakout cable.
The following table lists the supported transceivers.
Configuration notes:
- It is supported to mix 10Gb and 1Gb transceivers or to mix 25Gb and 1Gb transceivers. It is not supported to mix 10Gb and 25Gb transceivers.
- Transceiver AV1B is not supported in the OCP adapter due to thermal restrictions; use BF10 instead.
- Transceivers BF10, AV1B, and BYBJ are only supported at 25 Gb/s speed with the 57454 adapters.
The following table lists the supported optical cables.
The following table lists the supported direct-attach copper (DAC) cables.
Features
The adapters have the following features:
- Broadcom TruFlow technology integrates flow processing to provide hardware assisted processing of traffic flows with data path Acceleration. TruFlow enables efficient network flow processing and increases Virtual Machine density by offloading the server CPU to improve application performance.
- Broadcom adapters are the industry’s most secure Ethernet solution, leveraging Broadcom’s BroadSAFE® technology to provide unparalleled platform security via Silicon Root of Trust. Broadcom is the first Ethernet Adapter vendor to store authentication key and code in silicon to protect clients from maliciously modified firmware.
- The adapters support RoCEv2. RoCE (RDMA over Converged Ethernet) allows Remote Direct Memory Access (RDMA) traffic to be communicated over Converged Ethernet using Data Center Bridging (DCB). Broadcom’s Smart Congestion Control provides consistent and predictable performance for real world workloads plus scaling for heavily loaded network traffic making it ideal for clients looking for deterministic low latency.
- Support for Data Center Bridging (DCB), including IEEE 802.1Qbb Priority based Flow Control (PFC), 802.1Qaz Enhanced Transmission Selection (ETS), and 802.1Qau Quantized Congestion Notification (QCN) capabilities. DCB technology allows the device to provide lossless data delivery, prioritize low latency traffic, and share bandwidth among data center physical links.
- Support for SR-IOV to allow I/O transactions to bypasses hypervisors, which reduces latency by removing data copies and context switches between VM address space and hypervisor address space, when transmitting or receiving data over the network. The implementation supports 802.1Qbg Edge Virtual Bridging (EVB)
