100GbE dual-port QSFP28 adapter
This ConnectX-5 Ex network card delivers 100GbE connectivity through two belly-to-belly QSFP28 ports. It is built for single-host servers and storage nodes that require high-throughput InfiniBand or Ethernet links in an OCP 2.0 Type 2 form factor. The PCIe 4.0 x16 interface provides the bandwidth needed for line-rate performance.
PCIe 4.0 x16 lane requirement
The card operates at PCIe Gen 4.0 x16 with SERDES at 16.0GT/s, falling back to Gen 3.0 x16 at 8.0GT/s. A slot with fewer than 16 lanes will limit throughput below the advertised 100GbE per port. The OCP 2.0 Type 2 stacking height also demands a compatible cage; standard PCIe brackets will not fit.
Verify OCP cage and QSFP28 cabling
Before ordering, confirm your chassis accepts an OCP 2.0 Type 2 card with 3.07in by 4.33in dimensions and the belly-to-belly QSFP28 connector orientation. Ensure you have suitable 100GbE QSFP28 transceivers or direct-attach cables for the chosen protocol. Buyers needing a standard PCIe bracket or single-port connectivity should consider other models.

Spørsmål om denne varen
Which ConnectX-5 Ex variant matches the MCX546A-EDAN part number?
This is the dual-port 100 GbE QSFP28 OCP 2.0 Type 2 card with PCIe 4.0 x16 SERDES at 16.0 GT/s.
What Ethernet speeds does the adapter actually deliver in a server?
The card supports 10, 25, 40, 50 and 100 Gb/s Ethernet per port, limited by the QSFP28 transceiver and switch you install.
What does the PCIe 4.0 x16 interface cap in practice?
The SERDES runs at 16.0 GT/s, giving a raw lane rate that supports the full dual-port 100 GbE bandwidth.
