ConnectX-7 IC technical selection Q&A

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.
