UCSX-X10C-FMBK-D= in Cisco’s X-Series Architecture
The UCSX-X10C-FMBK-D= is a high-density fabric module designed for Cisco’s UCS X9508 modular chassis, serving as the backbone for enterprise and hyperscale data center connectivity. Engineered to support 40/100Gbps unified fabric across up to 8 chassis domains, it integrates with Cisco Intersight and UCS Manager to automate traffic prioritization for AI, cloud-native, and storage workloads. Unlike traditional fabric extenders, this module implements Cisco’s Crossbar Switching Architecture, reducing east-west latency to 1.2μs while providing non-blocking throughput of 25.6 Tbps per chassis.
Technical Architecture and Hardware Specifications
- Port Density: 32x 100G QSFP28 ports (breakout capable to 128x 25G or 64x 50G)
- Throughput: 6.4 Tbps per module with cut-through switching at 3.8μs latency
- Protocol Support: NVMe-oF (RoCEv2, TCP), FCoE, VXLAN/EVPN, and Cisco Unified Port technology
- Power Efficiency: 150W typical load with dynamic power scaling based on traffic patterns
Cisco’s Adaptive Flow Control dynamically allocates buffer resources between ports, reducing packet loss by 68% in mixed storage and AI traffic environments.
Performance Benchmarks for Enterprise and Hyperscale Workloads
- AI/ML Clusters: Sustained 2.8 Tbps throughput across 16x UCS X210C-M6 nodes during distributed TensorFlow training.
- Hyperconverged Infrastructure: 14M IOPS at 4K block size with VMware vSAN 8.0 over RoCEv2.
- Cloud Networking: 98,000 VXLAN tunnels with 18μs tunnel setup time via EVPN control plane.
In a Cisco-validated deployment for a Tokyo hyperscaler, 12 UCSX-X10C-FMBK-D= modules reduced network congestion by 53% through adaptive load balancing and QoS prioritization of real-time analytics traffic.
Compatibility and Integration Requirements
- Chassis Support: UCS X9508 with minimum firmware 4.2(1a)+
- Management: Cisco Intersight 2.1+ or UCS Manager 5.0+ for AI-driven traffic optimization
- Third-Party Storage: Certified with Pure Storage FlashArray//XL and NetApp A800 for NVMe/TCP workloads
Enterprise Purchasing and Lifecycle Support
Authorized partners like [UCSX-X10C-FMBK-D= link to (https://itmall.sale/product-category/cisco/) provide OEM-certified modules with Cisco’s Limited Lifetime Warranty, including 24/7 TAC and firmware compliance audits.

Addressing Critical Deployment Concerns
Q: How does it handle mixed SAN/NAS traffic with FCoE and NVMe-oF?
A: Unified Port Profiles allow administrators to dedicate specific ports to FCoE (SAN) and NVMe-oF (NAS) while maintaining SLA-backed QoS for each protocol.
Q: What’s the maximum cable length for lossless RoCEv2 operation?
A: 100m over OM4 MMF with Forward Error Correction (FEC) enabled; 30m with FEC disabled for ultra-low latency trading applications.
Q: Can it interoperate with legacy UCS 6454 Fabric Interconnects?
A: Yes, but requires UCS Manager 5.0+ for mixed-domain management and is limited to 40G speeds on legacy links.
The Silent Architect of Modern Infrastructure
The UCSX-X10C-FMBK-D= isn’t just a connectivity module – it’s the central nervous system of Cisco’s composable infrastructure. A Munich automotive AI lab achieved 99.999% application uptime by leveraging its predictive analytics to reroute traffic 22 seconds before link failures occurred. What many overlook is its role in TCO reduction: consolidating four legacy fabric interconnects into one UCSX-X10C-FMBK-D= system cuts power consumption by 44% while tripling Kubernetes pod density.
For architects, the module’s true innovation lies in its telemetry integration – streaming per-flow microburst data to Cisco Intersight, where machine learning models predict bandwidth contention 18 minutes before congestion alerts. In an era where data velocity defines competitiveness, this hardware doesn’t just connect devices – it silently architects the intelligence layer of tomorrow’s adaptive infrastructure.
