Built around the Broadcom/Marvell BCM57810S controller, this dual-port 10GbE SFP+ adapter delivers reliable throughput for servers and NAS builds. The BCM57810S supports PCIe 2.0 x8 bandwidth and SFP+ connectivity (DAC or 10GBASE-SR/LR optics), with SR-IOV for virtualization, PXE/iSCSI boot options, and 9K Jumbo Frames to reduce CPU overhead. It fits both full-height and low-profile chassis for flexible deployment in rackmount or compact cases. Ideal for ESXi/Proxmox/Hyper-V, TrueNAS, and 10Gb backbone aggregation. Also referred to as a PCI network adapter by users (PCIe interface).
