What network speed and protocols are supported by this adapter?

This adapter is specified as an InfiniBand HDR and Ethernet adapter operating at 100Gb. It is designed for use in environments where 100Gb connectivity is required, and where both InfiniBand HDR fabrics and Ethernet networks are in use. This allows the adapter to participate in high bandwidth fabrics and IP-based Ethernet infrastructures.

How many ports does the HPE P08238-001 provide and what connector does it use?

The HPE P08238-001 is a 1-port adapter that uses a QSFP56 connector. This single port provides a 100Gb link over QSFP56, which is commonly used with compatible QSFP56 cables or transceivers. When planning connectivity, ensure the attached switches or other endpoints also support QSFP56 at 100Gb.

Is the HPE P08238-001 suitable for low profile server installations?

Yes, the adapter is described as a standup low profile card. This indicates it is intended to fit low profile expansion slots in compatible servers. When integrating into server designs, confirm that the chassis supports low profile standup adapters in the required PCIe 3.0 x16 slot locations.

What type of deployment scenarios is this 100Gb adapter intended for?

The adapter is intended for scenarios requiring 100Gb connectivity using InfiniBand HDR or Ethernet, such as data center networking or fabric connections. With a single 100Gb QSFP56 port and PCIe 3.0 x16 interface in a standup low profile form factor, it fits rack server environments that need high bandwidth links while observing low profile mechanical constraints.
