Qnap QXG100G2SFE810 2-port QSFP28 100GbE network card

SKU CH-XP9X-HXP9Y MPN QXG100G2SFE810

Two-port QSFP28 network card delivering 100 GbE connectivity over a PCIe Gen4 x16 low-profile slot

  • Dual 100 GbE ports deliver massive bandwidth for data-intensive workloads
  • PCIe Gen4 x16 interface provides high-throughput connectivity to the host system
  • Low-profile form factor fits space-constrained servers and workstations
  • QSFP28 transceiver support enables flexible fibre or copper cabling choices
  • QNAP engineering ensures reliable performance in demanding network environments

Dual-port QSFP28 100 GbE adapter

The Qnap QXG100G2SFE810 is a low-profile PCIe Gen4 x16 network card with two QSFP28 ports. Each port delivers 100 Gb/s Ethernet connectivity for servers or workstations that need high-throughput links. The x16 interface supplies the lane bandwidth required for dual-port line-rate operation.

Suited for dual 100 GbE uplinks, not for more ports

This card suits administrators adding a pair of 100 GbE uplinks to a host with a free x16 slot. Buyers who need more than two ports, a different connector type, or a narrower slot profile should look at other models. The fixed two-port layout cannot be expanded on the board itself.

PCIe Gen4 x16 electrical interface

The card requires a PCIe Gen4 x16 slot to provide sufficient bandwidth for both 100 GbE ports simultaneously. Systems limited to x8 or Gen3 electricals will restrict total throughput. Verify the motherboard or riser can supply a full x16 Gen4 link before purchase.

Questions about this item

How does a 100GbE link behave once the card is installed in a server?

Each of the two QSFP28 ports can carry up to 100GbE of throughput, so the card delivers two independent 100GbE connections when cabled with compatible modules.

What does the PCIe Gen4 x16 interface limit in practice?

The x16 lane width provides enough bandwidth for both 100GbE ports to run at line rate simultaneously without host-bus saturation.

What slot and bracket size does the card need to fit?

It requires a full-length PCIe x16 slot and ships with a low-profile bracket for 2U or slimmer chassis.
