They are both Intel 82599 based and use the ix driver: Card 1: GLOTRENDS ST7315 10Gb SFP+ Ethernet Network Card with Intel 82599EN Controller, PCIE 2.0 X4 Interface Also, these work: Card 2: 10Gtek for Intel E10G42BTDA 82599ES Chip 10GbE Ethernet Converged Network Adapter X520-DA2/X520-SR2, PCI-E X8 Dual SFP+ Port The NICs aren't purely RJ45, but with these RJ45 copper SFP+ modules: Modules: 10Gtek 1.25/2.5/5/10G-T SFP+ to RJ45 Copper Module - 10GBase-T Transceiver for Cisco SFP-10G-T-S Ubiquiti unifi UF-RJ45-10G D-Link Supermicro Broadcom Linksys up to 30m Pack of 2 they work well with my existing infrastructure. The only caveat is that you must ensure the motherboards have the proper number of PCIe lanes in their slots. I.e. the dual port needs 8 lanes and the single port seems to need 4 lanes, so plan accordingly.
