How many network ports are available on the HPE P65333-B21 adapter?

The adapter is specified as a 2-port QSFP112 model. This means it provides two QSFP112 network ports for connectivity. Each port is associated with InfiniBand NDR200 and Ethernet 200G capabilities based on the product name, enabling dual high-speed links from a single adapter card in a supported server.

Which network technologies are supported by the HPE P65333-B21 adapter?

According to the model description, the adapter supports InfiniBand NDR200 and Ethernet 200G. This indicates it is designed for use in both InfiniBand and Ethernet environments at a 200G-class speed. The dual-protocol nature allows the same hardware platform to participate in different fabric types, depending on system and network configuration.

What is the speed class of the HPE P65333-B21 network connections?

The adapter is identified as an InfiniBand NDR200 Ethernet 200G solution, indicating 200G-class networking. Its two QSFP112 ports are intended for 200G links in both InfiniBand NDR200 and Ethernet 200G contexts. This makes the card suitable for deployments that target 200Gb fabrics rather than lower-speed network infrastructures.

What type of transceivers or cables does the HPE P65333-B21 require?

The product name specifies QSFP112 for its two ports, which defines the mechanical interface for transceivers and cables. This means it is designed for QSFP112-form-factor modules and cabling. Procurement teams should select QSFP112-compatible optics or direct-attach cables that match the intended InfiniBand NDR200 or Ethernet 200G deployment.

Product overview

The HPE InfiniBand NDR200 Ethernet 200G 2-port QSFP112 PCIe5 x16 MCX755106AC-HEAT Adapter P65333-B21 is designed as a high-speed network adapter for demanding environments. It combines InfiniBand NDR200 and Ethernet 200G capabilities in a single solution, enabling flexible deployment in mixed-protocol infrastructures. Dual QSFP112 ports provide 200G connectivity per port, aligning with modern data center throughput requirements. The PCIe 5.0 x16 interface supports high-bandwidth host connectivity, suitable for dense server platforms and performance-sensitive workloads. As a 2-port adapter, it supports configurations requiring redundancy or link aggregation based solely on its two QSFP112 interfaces. This model is part of a 200Gb InfiniBand and Ethernet category, focusing on reliable, high-performance packet transport. All characteristics are derived from the known model designation and form factor, without additional undocumented features.
