Lenovo 4XC7A08242 network card Internal Fiber 25000 Mbit/s

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 adapter supports both RoCEv1 and RoCEv2 simultaneously. 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 predictive 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). Abstract.
