What protocols does this adapter support?

The provided specifications identify support for 40Gb/s QDR InfiniBand and 10Gb/s Ethernet. Those are the only protocol details included in the source data, so the confirmed capability set is limited to those two network modes.

The product data states that this is a dual-port adapter and also lists two QSFP dual-function ports. That means the verified port count is 2, with both ports identified in the supplied specifications.

What form factor is listed for this product?

The adapter is described as a FlexibleLOM QSFP product in the supplied data. That form factor is part of the product identity and is the only mechanical interface detail confirmed in the provided specifications.

Is this product for InfiniBand, Ethernet, or both?

The source data indicates both. It is listed as supporting 40Gb/s QDR InfiniBand and 10Gb/s Ethernet, so the adapter is defined as a dual-protocol network part in the supplied specifications.

What is the product identifier for procurement records?
