Introduction
The ThinkSystem Broadcom 57504 10/25GbE SFP28 4-port adapters are high-performance low-power 25 Gb Ethernet adapters with a PCIe 4.0 host interface that offers TruFlow intelligent flow processing and supports advanced networking technologies such as VXLAN, NVGRE, Geneve, RoCE, SDN and NFV, to facilitate the management of data networks and to enable service provider solutions. The adapters are available in both PCIe or OCP 3.0 form factors.
Did you know?
These adapters are based on the Broadcom BCM57504 scalable Ethernet controller architecture, which is designed to build highly-scalable, feature-rich networking solutions. The adapters are an ideal choice for enterprise and cloud-scale networking and storage applications, including high-performance computing, telco, machine learning, storage disaggregation, and data analytics.
Part number information
The ordering information is listed in the following table.
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.
25Gb transceivers: When installed in this 25Gb Ethernet adapter, 25Gb transceivers are designed to operate at either 25 Gb/s or 10 Gb/s speeds as listed in the description of the transceiver, however the speed also depends on the negotiation with the connected switch. In most configurations, this negotiation is automatic, however in some configurations you may have to manually set the link speed or FEC mode.
The following table lists the supported fiber optic cables and Active Optical Cables.
The following table lists the supported direct-attach copper (DAC) cables.
Features
Driven by the growing need for higher server bandwidth and storage capacity to support new and emerging applications (Machine Learning, HPC, Multi-node containers, NVMe, Web 2.0, NVMe storage disaggregation, HCI), enterprises, telcos and cloud providers are modernizing their data centers by adopting latest networking technologies, such as server virtualization and NVMe-oF™. The resulting expansion in data volumes increases server-to-server traffic and CPU loads for networking tasks.
With its market-leading hardware acceleration technologies, the ThinkSystem Broadcom 57504 10/25GbE SFP28 4-port Ethernet Adapters addresses these performance and service demands of mega-scale data center networks with high throughput and advanced flow processing. Features such as TruFlow™ increase VM density up to 50 percent, freeing more CPU cycles for additional virtual machines. On-chip tunneling protocol processing for Geneve, VXLAN, and NVGRE provides up to a 5X throughput increase while lowering CPU utilization up to 90 percent compared to software-only solutions.
The adapters have the following features:
- 4x 25GbE network connectivity for high availability features eliminating throughput bottlenecks for data-intensive applications
- Industry’s best performing and longest-reach 25G NRZ SerDes dramatically lowering TCO by reducing cable costs by 50% and doubling port density
- PCIe 4.0 x16 support maximizing the full potential of servers compliant with the PCI Express® 4.0 specification, providing seamless interoperability and doubling server throughput while saving PCIe lanes
- Third generation Broadcom TruFlow™ engine for intelligent flow processing to increase server VM density and accelerate vSwitch processing of traffic flows with data path Acceleration. TruFlow enables efficient network flow processing, increases Virtual Machine density by offloading the server CPU to improve application performance.
- RoCE (RDMA over Converged Ethernet), allows Remote Direct Memory Access (RDMA) traffic to be communicated over Converged Ethernet using DCB. GPU Compute over RoCE enables scalable GPU clusters up to hundreds of nodes using Ethernet for HPC, AI, and ML applications.
- 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.
- Broadcom adapters are the industry’s most secure PCIe Ethernet controller solution, leveraging Broadcom’s BroadSAFE® technology to provide unparalleled platform security via Silicon Root of Trust (RoT). Broadcom is the first Ethernet Adapter vendor to store authentication key and code in silicon to protect clients from maliciously modified firmware.
- Broadcom’s TruManage™ enhances server manageability, network management, and security for data center deployments. TruManage supports widely deployed management standards including DMTF NC-SI, MCTP, PLDM, and SPDM specifications.
- Support for SR-IOV which bypasses the hypervisor, reducing the 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).
- Support for Data Center Bridging (DCB), including IEEE 802.1Qbb Priority based Flow Control (PFC) and 802.1Qaz Enhanced Transmission Selection (ETS). DCB technology allows the device to provide lossless data delivery, prioritize low latency traffic, and share bandwidth among data center physical links.
- In-band Network Telemetry features provide end-to-end real-time monitoring capability, enabling data center operators to fine tune their networks for maximum performance.
