Add a 10GbE port to your server for the price of a consumer SSD. The GLOTRENDS ST7507 is built on the battle-tested Mellanox ConnectX-3 controller (MCX341A-XCGN), a proven design trusted in data centers for years and now the smartest budget path to 10G networking. One SFP+ port auto-negotiates 10G or 1G, so you can connect to a 10G switch today and keep 1G links working tomorrow. The PCIe 3.0 x8 host interface fits any x8 or x16 slot, and hardware offloads for TCP/IP, checksum and segmentation keep your CPU free for real work file transfers stay fast without spiking processor load. Where this card shines: NAS builds (TrueNAS, Unraid), home labs (Proxmox, ESXi), software routers (pfSense/OPNsense), and SMB file servers. RoCE RDMA support reduces latency for iSCSI and NFS storage traffic, while SR-IOV/VMDq virtualization keeps dozens of VMs talking to the network without bottlenecking the hypervisor. Specifications: 1x SFP+ (10GbE/1GbE) | PCIe 3.0 x8 | RoCE v1 RDMA | SR-IOV/VMDq | DCB, jumbo frames up to 9.6KB | PXE boot | Aluminum heat sink, low-profile + full-height brackets. Drivers: Windows 10/11, Windows Server, RHEL/CentOS/Ubuntu/Debian, VMware ESXi via WinOF-2/MLNX_OFED. Mature, stable and widely documented by the global Mellanox community.
