How many network ports are available on the HPE InfiniBand NDR200 P45642-B21 adapter?

The adapter is specified as a 1-port OSFP device. This indicates it provides a single network port that uses the OSFP form factor. Such a configuration is appropriate when architectures prefer one dedicated connection per adapter, for example to separate traffic patterns, links, or roles within an InfiniBand fabric.

What host interface does the HPE P45642-B21 adapter require?

The product description places this adapter in the NDR200 1-port OSFP PCIe 5.0 x16 category. This means it is designed for systems that provide a PCIe 5.0 x16 slot for host connectivity. Ensuring that servers have available PCIe 5.0 x16 expansion capability is important for correct installation and integration.

Is the HPE P45642-B21 adapter suitable for enterprise environments?

Yes, the adapter is explicitly tagged with an enterprise product level. This classification aligns it with data center and professional IT environments where standardized InfiniBand and Ethernet adapters from HPE are deployed. For enterprise procurement teams, this designation helps confirm that the product targets managed, production-grade infrastructures.

What optical interface standard does the HPE P45642-B21 adapter use?

The HPE P45642-B21 is described as a 1-port OSFP adapter. OSFP refers to the form factor of the network port, which connects to OSFP-compatible modules or cabling. When planning deployments, it is important to match this OSFP interface with corresponding OSFP optics to ensure physical compatibility.
