The Broadcom BCM57840S is a purpose-built quad-port 10GbE/40GbE network interface card designed for data centers operating at scale. With four SFP+ ports delivering up to 40 Gbps aggregate throughput over a single PCIe 3.0 x8 slot, this NIC enables enterprises to consolidate multiple physical adapters into one high-density solution—critical for space-constrained server deployments in cloud infrastructure and virtualized workloads.
Purpose-engineered for virtualization-heavy environments, the BCM57840S supports up to 128 SR-IOV virtual functions, allowing a single physical adapter to service dozens of guest VMs without performance degradation. Hardware-accelerated RoCEv2 RDMA and full TCP offload (TOE) reduce CPU overhead on latency-sensitive applications, while FCoE support maintains compatibility with legacy SAN architectures. The adapter's sub-25W power envelope makes it ideal for large-scale deployments where thermal and power-delivery constraints directly impact infrastructure density.
