What networking class is specified?

The adapter is specified as InfiniBand EDR. The product data also places it in the 100Gb category, so the grounded networking description is an InfiniBand EDR adapter in the 100Gb class.

How many ports are listed?

The supplied product name and category both describe it as a 2-port adapter. No additional port details are provided, so the grounded answer is limited to two ports.

What form factor is listed?

The product is identified as a mezzanine adapter. The product name also includes the phrase Mezzanine FIO Adapter, which confirms that the grounded form factor description is mezzanine.

Does the provided data include interface details beyond the product category?

No. The only grounded networking descriptors are InfiniBand EDR, 100Gb, 2-port, and mezzanine adapter. The specification fields for Networking Ports and Interfaces are blank in the supplied source data.
