SFP+ or 10GBASE-T

Pick the port type before the chipset, because it decides what plugs in at the other end.

PortWhat connectsReach (manufacturer)Controllers on this page
SFP+ cage10GBASE-SR or 10GBASE-LR optics, or SFP+ direct-attach copper (Intel X710 brief)Set by the optic or cableIntel X710 and X520; Broadcom 57412 and 57810; QLogic, Emulex, Solarflare and Chelsio cards
10GBASE-T (RJ45)Twisted-pair copper100 m on Cat 6A, 55 m on Cat 6; 1000BASE-T to 100 m on Cat 5e or better (Intel X550 brief)Intel X550, X540 and X710; Broadcom 57416

Broadcom documents the 57412 as two 10Gb SFP+ ports and the 57416 as two 10GBASE-T ports, each built as a PCIe Gen3 x8 card or an OCP 3.0 card.

Slots and other form factors

Everything on this page is a slot card, a PCIe adapter or an OCP NIC. Dell's R750 guide shows the 15th-generation PowerEdge trading the rNDC slot for OCP 3.0, so OCP cards suit those servers while PCIe cards fit any free slot of the right height. Dell rNDCs and blade cards have their own pages, network daughter cards and mezzanine adapters, and cards bought for FCoE or iSCSI storage offload are under converged network adapters.

Pair SFP+ cards with 10GBASE-SR SFP+ transceivers or direct-attach cables. Other speeds and port counts: dual-port, quad-port, gigabit and 25GbE adapters, all in cards and controllers. Every card is sold with an Enterasource warranty, and the listing says for how long.
