FAQ
Ask a QuestionFind answers to common questions about our products.
Why is MCX623105AC-CDAT single-port even though other CDAT models are dual-port?
For this family, the port count is mainly reflected by the 105 versus 106 part of the OPN. MCX623105AC-CDAT is the single-port 100GbE QSFP56 version, while MCX623106AC-CDAT is the dual-port 100GbE QSFP56 version
How is MCX623105AC-CDAT different from MCX623105AN-CDAT and MCX623105AE-CDAT?
MCX623105AC-CDAT enables both Crypto and Secure Boot. MCX623105AE-CDAT enables Crypto but not Secure Boot, while MCX623105AN-CDAT disables both Crypto and Secure Boot.
What type of deployment benefits from the Crypto-enabled version?
It is useful for secure cloud, storage, and virtualized environments where inline security acceleration matters. NVIDIA lists IPsec, TLS, and AES-XTS encryption capabilities for ConnectX-6 Dx, along with hardware Root-of-Trust and secure firmware update features.
