10GB NIC option available...
Seeking reliable components to link two Windows 10 machines using 10Gbps NICs (Point-to-Point). Both systems are on a server setup that may eventually use FreeNAS. Distance is about 10 meters. Uncertain if RJ45 or SFP+ (fiber or copper) is best—thanks for guidance. Concerned about compatibility of the Intel X520-DA2, Mellanox MCX311A, and other parts. Should I opt for newer gear or stick with older models? Any additional suggestions would be appreciated.
Ten meters is quite far for SFP+ unless you're using fiber; I recommend choosing the cheapest RJ45 option instead. A decent CAT6 cable should suffice for stable 10Gbps performance at that range.
Intel cards offer a more affordable alternative compared to ASUS, sharing the same chip technology as Aquantia. However, current listings only show 7m DACs, and even a 10m option doesn’t seem significantly cheaper than ASUS. I prefer SFP+ DACs because they’re compact and work well with Ethernet cables, which are easier to manage over longer distances. If you plan to relocate your equipment later, using RJ45 provides flexibility with up to 100m of cable.
