BlueField-3 AUX technical selection Q&A
Owner-confirmed and documentation-backed questions with explicit variant applicability and source boundaries.
These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.
The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.
Is this a NIC or a supporting component?
Applicable catalog candidates: 930-9DAX4-0035-000, 930-9DAX5-0015-000.
It is an auxiliary PCIe connection kit, not a standalone Ethernet or InfiniBand adapter.
