Broadcom 40GbE Network Interface Card is a 40 Gigabit Ethernet server adapter using QSFP+ connectors — the standard connector for 40GbE (not RJ45, and not the QSFP28 used by 100GbE). Cards in this class commonly use an Intel XL710-class or Mellanox ConnectX-3/3 Pro chipset, over a PCIe 3.0 x8 host interface capable of dual-port line rate.
Typical Use
40GbE fits servers that have outgrown 10GbE but don't need a full 100GbE upgrade — high-throughput storage fabric, datacenter core/uplinks, and database or virtualization hosts under heavy network load. You'll need matching QSFP+ transceivers/DACs and switch ports rated for 40GbE — confirm your switch infrastructure supports it before ordering.
