HPE 200Gb 2 Port InfiniBand HDR/Ethernet PCIe4 OCP3 Adapter

The HPE P31348-B21 is a dual-port adapter that delivers 200Gb per second of throughput over InfiniBand HDR or Ethernet. It plugs into a PCIe 4.0 x16 slot and uses a QSFP56 connector, giving HPE ProLiant DL Gen10 Plus servers the bandwidth and sub-microsecond latency that demanding workloads require.

Each port can run at 100Gb per second, or you can combine them for 200Gb per second when your application and switch fabric support link aggregation. The adapter’s OCP 3.0 small form factor fits neatly into modern server trays, so you gain high-speed networking without sacrificing expansion space. Because it supports both direct-attach copper and active optical cables, you can choose the cabling that best matches your distance needs and budget.

In a high-performance computing cluster, this card helps researchers accelerate simulations, genomic analysis, and large-scale data analytics. It also benefits enterprise data centers that run real-time financial modeling, artificial intelligence training, or latency-sensitive virtualized workloads. By moving to 200Gb per second, many teams find they can shrink the number of switches that would otherwise be required in a 100Gb topology, which simplifies management and lowers power consumption.

Deployment is straightforward: slide the adapter into an OCP 3.0 slot, connect QSFP56 cables, and configure the ports for InfiniBand HDR or Ethernet based on your fabric design. With a three-year warranty from HPE, you gain confidence that the card will continue to perform under continuous, high-duty cycles.
