How many network ports are available on the HPE Apollo A10 InfiniBand adapter?

This adapter is identified as a 2-port design. The model name explicitly states it is a 2-port InfiniBand EDR 100Gb adapter, allowing two InfiniBand connections from a single mezzanine card in an HPE Apollo server. This dual-port configuration helps in building redundant or multi-path InfiniBand topologies.

For which platforms is the HPE 843400-B21 mezzanine adapter intended?

The adapter is described as an Apollo A10 InfiniBand EDR 100Gb 2-port 840z mezzanine FIO adapter for HPE Apollo servers. This indicates it is designed specifically for use within HPE Apollo platforms that accept 840z mezzanine FIO adapters, aligning the hardware closely with Apollo server configurations.

What is the data rate supported by this HPE Apollo InfiniBand adapter?

The adapter is specified as an InfiniBand EDR 100Gb adapter. The EDR designation and 100Gb notation indicate that it is aligned with enhanced data rate InfiniBand at a nominal 100Gb, which is relevant when planning link capacities and matching to existing InfiniBand EDR fabrics.

What is meant by the 840z mezzanine FIO description for this adapter?

The product is labeled as an 840z mezzanine FIO adapter, indicating that it uses the 840z mezzanine interface and is intended as a factory integrated option. This means the adapter is designed to install in the dedicated mezzanine area of compatible HPE Apollo servers when configured during system build.
