Dual-port 40G QSFP+ server NIC

The StarTech PEX40GQSFDPI is a dual-port 40G QSFP+ network interface card built on the Intel XL710-BM2 controller. It installs in a PCI Express 3.0 x8 slot and presents two open QSFP+ cages that accept MSA-compliant transceivers or direct-attach cables. The adapter is designed for servers and workstations that need 40GbE connectivity for storage, virtualisation or high-throughput workloads.

Suited for redundancy and aggregation

This card suits administrators who need two 40G links for link redundancy or port aggregation in a single x8 slot. It supports multimode and single-mode fibre, PXE boot, 9K jumbo frames and VLAN tagging across Windows, Windows Server, Linux and VMware ESXi 5.0/5.1+. Environments that require more than two 40G ports, or that lack a PCIe 3.0 x8 slot, should consider a different adapter.

PCIe 3.0 x8 host interface requirement

The single specification that decides fit is the PCI Express 3.0 x8 host interface; the system must provide an x8 electrical connection (x8 or x16 physical) for the card to operate at its rated 40Gbps per port.

Questions about this item

What size PCIe slot and bracket clearance does the PEX40GQSFDPI require?

The card uses a PCI Express 3.0 x8 interface and measures 4.8 inches wide by 7.1 inches deep; full-height and low-profile brackets are included.

Which step is often missed when installing the Intel XL710 adapter in a server?

After seating the card in the x8 slot, you must attach the QSFP+ transceivers or direct-attach cables before the link will come up.

When will the QSFP+ modules or cables need replacement on this 40GbE NIC?

Replace transceivers or DACs when link errors increase or after a fiber break; the Intel XL710 controller itself has no user-serviceable parts.
