About the Broadcom BCM57508 NetXtreme-E 100GbE Ethernet Adapter
The Broadcom BCM57508 NetXtreme-E 100GbE Ethernet Adapter delivers enterprise-grade connectivity through a single QSFP28 port supporting 100GBASE-SR4, 100GBASE-LR4, and 100GBASE-CR4 (DAC) standards, with backward compatibility for 25GbE and 10GbE workloads. Built on the Broadcom BCM57508 ASIC and interfacing via PCIe 4.0 x16, this adapter (part number BCM957508-N1100G) consumes approximately 25W typical power and operates reliably across 0°C to 55°C environments, making it suitable for demanding data center deployments where network engineers and storage architects require deterministic, high-speed fabric connectivity.
Advanced offload capabilities include RoCEv2 RDMA for low-latency cluster communications, NVMe over Fabrics (NVMe-oF) initiator and target support for streamlined storage integration, and comprehensive TCP/IP offload with stateless checksum handling and LSO/LRO. Broadcom's virtualization support extends to SR-IOV with up to 256 Virtual Functions, enabling multi-tenant cloud and HCI environments. Management is handled through Broadcom NetXtreme software suite and IPMI NC-SI sideband capabilities. The adapter supports Linux (RHEL, SLES, Ubuntu), Windows Server 2016/2019/2022, and VMware ESXi 6.7/7.0/8.0, while IEEE 1588v2 PTP hardware timestamping and RSS multi-queue support round out the feature set. Available in standard PCIe low-profile and full-height bracket configurations, the BCM957508-N1100G integrates seamlessly into existing infrastructure.
Deployment Scenarios
- High-performance computing clusters requiring sub-microsecond RDMA latency and deterministic packet delivery
- NVMe-oF storage networks consolidating block and fabric connectivity on a single 100GbE uplink
- Virtualized data centers leveraging SR-IOV and 256 VF support for secure multi-tenant workload isolation
- Financial services and real-time analytics platforms depending on IEEE 1588v2 precision time synchronization
- Hyperscale infrastructure modernization from 10/25GbE to 100GbE with backward compatibility protection
