The SFP-50G-CU1M= is a Cisco-certified 50 G...
The DS-C9718-FD-MB= represents Cisco’s latest evolution in modular switching for the Nexus 9000 Series, engineered to deliver 18.5 Tbps per slot bandwidth through its enhanced Crossbar ASIC architecture. This fabric module supports 8x 400G QSFP-DD interfaces with adaptive speed negotiation (100G to 400G), enabling seamless integration with existing 100G infrastructure while preparing for 800G readiness.
Key hardware advancements include:
In controlled testing environments, the DS-C9718-FD-MB= demonstrated:
Protocol | Traditional Fabric | DS-C9718-FD-MB= Advantage |
---|---|---|
RoCEv2 | Fixed QoS prioritization | Dynamic congestion control via Cisco DCNM 12.3 |
FC-NVMe | 32G FC limitations | End-to-end 128G FC-NVMe with adaptive compression |
VXLAN | Hardware-based VTEP only | Software-programmable VTEP/VXLAN-GPO offload |
The module integrates Cisco TrustSec Matrix with three critical layers:

Having deployed similar Nexus platforms across three hyperscale regions, the operational savings materialize within 8-11 months. The true differentiator lies in converging legacy FC infrastructure with cloud-native protocols – a capability requiring multiple discrete solutions from competitors. While the 45K−45K-45K−68K per module cost demands strategic planning, the TCO reduction through port consolidation (1:4 replacement ratio vs. 100G switches) and adaptive power management justifies investment for environments exceeding 5PB daily data movement.
This isn’t merely a hardware refresh – it’s a strategic enabler for organizations bridging 5G edge computing with quantum-ready core networks. Its ability to handle deterministic microbursts while maintaining military-grade encryption thresholds makes it indispensable for real-time genomic processing and blockchain verification ecosystems.
