Which protocols or fabrics are supported by this adapter?

According to the product category description, this adapter supports InfiniBand EDR or Ethernet operation. This allows it to integrate into InfiniBand-based fabrics, Ethernet networks, or environments that use both technologies, while maintaining a single 100Gb QSFP28 port for connectivity.

What type of network connector does the P23832-001 use?

The adapter is identified as an 840QSFP28 100Gb 1-Port Adapter and is listed under a PCIe 3.0 x8 QSFP28 Adapter category. This indicates that its network connectivity uses a QSFP28 interface, which is commonly deployed for 100Gb links in data center and HPC networks.

How many ports are available on the HPE 840QSFP28 adapter?

The product is described as a 100Gb 1-Port InfiniBand EDR or Ethernet 840QSFP28 adapter, meaning it provides a single network port. This 1-port configuration is suitable for designs where each server or node is planned around one high-speed 100Gb connection instead of multiple lower-speed interfaces.

What is the full identification for this HPE network adapter?

The adapter is identified by the brand HPE, the model name 840QSFP28 100Gb 1-Port Adapter, and the SKU P23832-001. Together, these identifiers ensure precise product selection and make it easier for procurement and engineering teams to match specifications and documentation.

Product overview

The HPE 840QSFP28 100Gb 1-Port Adapter P23832-001 is designed for environments that require high bandwidth connectivity in a compact, single-port form factor. This adapter supports InfiniBand EDR or Ethernet operation, allowing flexible deployment in infrastructures that use either fabric type. The single network port uses a QSFP28 interface, delivering 100Gb connectivity for demanding data paths. As a 100Gb 1-port InfiniBand EDR or Ethernet 840QSFP28 adapter, it is suitable for data center, high performance computing, or other bandwidth-intensive workloads that benefit from high-throughput links. With its 100Gb capability and QSFP28 interface, IT teams can standardize on a widely adopted high-speed connector while maintaining protocol flexibility between InfiniBand EDR and Ethernet. This makes the P23832-001 a practical choice for consolidating network interfaces where both technologies are present.
