FAQs

Q: What Cisco UCS servers support this network card?
A: The UCSC-P-N7Q25GF is qualified for Cisco UCS C220 M7 and C240 M7 rack servers. It can be installed in Riser 1, 2, or 3 PCIe slots that provide sufficient power and airflow for data center operation.

Q: What is the difference between the AS and AC variants of ConnectX-7?
A: The MCX713104AS-ADAT variant has cryptographic functions disabled, while the AC variant includes crypto capabilities. Both support secure boot. The AS variant is suitable for most general data center networking applications.

Q: Can I use this card for both 10GbE and 25GbE connections?
A: Yes, the card supports auto-negotiation and can operate at 10 Gb/s or 25 Gb/s per port, providing flexibility for mixed-speed network environments. Each SFP56 port adapts to the transceiver and link speed requirements.

Q: What are the key advantages of RDMA over Converged Ethernet on this card?
A: RoCE support enables direct memory access between servers without CPU involvement, drastically reducing latency and CPU overhead. This is ideal for storage replication, virtualization clusters, and high-performance computing workloads requiring microsecond-level response times.

Q: Does this card require special drivers or firmware for Cisco UCS servers?
A: The card is pre-qualified for Cisco UCS M7 servers and works with standard NVIDIA ConnectX-7 drivers. Always verify compatibility using the Cisco Hardware Compatibility List and ensure server firmware is up to date for optimal performance.
