About the Broadcom BCM957508A5082C 50GbE OCP NIC 3.0 Adapter
For low-latency workloads, NIC offload capacity directly translates to freed CPU cycles—and the Broadcom BCM957508A5082C delivers 50GbE aggregate throughput with comprehensive hardware acceleration built into the Broadcom BCM57508 (Thor) controller ASIC. This OCP NIC 3.0 adapter consolidates dual 25GbE ports into a single small form factor card, enabling network engineers and infrastructure architects to maximize fabric density without sacrificing performance. With support for TCP/UDP/IP checksum offload, TSO, LRO, VXLAN offload, and GENEVE offload, this adapter reduces per-packet CPU overhead while maintaining line-rate forwarding across both SFP28 ports.
The BCM957508A5082C integrates RoCEv2 (RDMA over Converged Ethernet v2) for ultra-low-latency remote memory operations, making it ideal for high-performance computing and real-time data center workloads. SR-IOV virtualization support enables efficient multi-tenant deployments, while Broadcom NIC management via NC-SI (Network Controller Sideband Interface) simplifies out-of-band control. Data center bridging features—DCBX, PFC, and ETS—ensure lossless, priority-aware packet delivery. The card operates across Linux, Windows Server, and VMware ESXi environments, connecting via PCIe 4.0 x8 host interface and supporting both 10GbE and 25GbE per-port data rates. IT procurement teams evaluating high-performance network fabric upgrades will find this OCP NIC 3.0 specification–compliant design delivers enterprise-grade reliability with modern offload capabilities.
