Broadcom 57810S-10G-2s-x8 Dual Port 10GbE SFP Plus PCIe Adapter

The Broadcom BCM57810S-based 57810S-10G-2S-X8 is a dual-port 10 GbE SFP+ PCIe adapter for servers, delivering two independent 10 GbE SFP+ interfaces through a PCIe x8 host connector (PCIe 2.0 x8). Built around Broadcom’s BCM57810S FastLinQ controller, the card provides two SFP+ ports that accept 10GbE transceivers, enabling flexible fiber or fiber-copper connectivity for high-throughput workloads in rack- or tower-class servers. The PCIe add-in card is designed to fit into a PCIe x8 slot and is commonly marketed as a 57810S 10GBASE‑SFP+ dual-port NIC, with vendor listings emphasizing the two SFP+ sockets and x8 PCIe interface. Reported specifications indicate up to 10 Gbps per port when paired with appropriate transceivers, supporting scalable 10GbE networking for virtualization hosts, data-center uplinks, and storage-network fabrics. Some documentation and retailer listings also note 1G/10G operation on the SFP+ ports and broader HBA use cases such as iSCSI and FCoE, depending on driver and firmware support. Driver and OS support is typically available for Windows, Linux, and VMware ESXi environments, though exact compatibility depends on the OS version and vendor driver package.
