What bandwidth does the HPE 843420-001 adapter support?

The adapter supports InfiniBand EDR at 100Gb, as indicated by its description as an InfiniBand EDR 100Gb 2-Port 840Z Mezzanine FIO Adapter. This bandwidth level aligns with high-performance fabrics where fast data transfer between nodes is important for clustered, technical, or data-intensive workloads.

How many ports are available on the HPE 843420-001 adapter?

The HPE 843420-001 is described as a 2-Port 840Z Mezzanine FIO Adapter, meaning it provides two physical network ports. These dual ports allow for configurations that can use multiple links per server, such as for higher aggregate bandwidth or for separate fabric paths within InfiniBand EDR environments.

What form factor does the HPE 843420-001 use?

This adapter uses an 840Z Mezzanine FIO form factor, indicating it is designed as a mezzanine card rather than a standard PCI Express add-in card. The mezzanine design allows it to connect via dedicated mezzanine interfaces on supported servers, which is particularly useful in dense or specialized systems that require flexible I/O options.

For what type of environments is InfiniBand EDR 100Gb suitable on this adapter?

InfiniBand EDR 100Gb on this adapter is suitable for environments where high-bandwidth and low-latency interconnects are needed, such as clustered servers or technical computing workloads. The 2-port 100Gb capability allows systems to participate in InfiniBand fabrics that support demanding data movement and communication patterns.
