What type of network interface does this DPU adapter use?

This adapter uses a QSFP112 interface for its single network port. QSFP112 is a connector form factor associated with 400Gb connectivity. When planning deployment, it is important to match this interface with compatible QSFP112 based transceivers or cabling in top of rack and aggregation switches. This ensures end to end physical layer compatibility.

How many ports are available on the HPE NVIDIA BF3 3240 adapter?

The model description defines this product as a 400Gb 1 port QSFP112 HHHL B3140H DPU adapter. This indicates that there is one network port on the card, operating at a 400Gb rate. Capacity planners should treat each adapter as providing a single high speed link when designing server to switch or fabric connectivity.

What category does the P66584-001 adapter belong to?

The adapter is categorized as a PCIe 400Gb Ethernet and InfiniBand data processing unit, specifically a 1 port QSFP112 400Gb HHHL adapter. This classification helps buyers understand that it fits into PCIe server slots and is intended for high speed networking scenarios where a data processing unit is required rather than a basic NIC.

What is the form factor of this NVIDIA BF3 3240 DPU adapter?

The product name identifies it as an HHHL adapter, which stands for half height half length. This indicates that the card is designed to fit in PCIe slots that accommodate shorter and lower profile adapters. Infrastructure teams should confirm that their server platforms support HHHL cards when planning deployments of this DPU adapter.
