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.

Table 1. Ordering information

The PCIe adapters, when shipped as a stand-alone option part number, include the following items:

• One Broadcom adapter
• An attached full-height (3U) bracket, and a low-profile (2U) bracket that can be substituted if needed
• Documentation flyer

Supported transceivers and cables

The adapters have one or two 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.

Mixing transceivers: 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.

Transceivers AV1B and BF10 are only supported at 25Gb/s speed on the PCIe adapter (4XC7A08238).
The transceivers are supported at both 10Gb/s and 25Gb/s speeds on the OCP adapter (4XC7A08237).

25Gb transceivers: When installed in this 25Gb Ethernet adapter, certain supported 25Gb transceivers (as listed in the above table) are designed to operate at either 25 Gb/s or 10 Gb/s speeds, depending 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.

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 PCIe 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 keys and code in silicon to protect clients from maliciously modified firmware.
• The adapters support RoCEv2. RoCE (RDMA over Converged Ethernet), which allows Remote Direct Memory Access (RDMA) traffic to be communicated over Converged Ethernet using 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 which bypasses the hypervisor reduces 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)
