UCS-FI-6454-CH: Unified Fabric Interconnect for Hyperscale AI/ML and Enterprise Workloads

Core Architecture & Technical Specifications

The ​​UCS-FI-6454-CH​​ represents Cisco’s fourth-generation 1RU fabric interconnect optimized for hybrid cloud deployments and AI/ML infrastructure. Built on ​​Cisco Cloud Scale ASIC technology​​, this unified switch delivers ​​3.82 Tbps switching capacity​​ with 1.44 billion packets/sec forwarding rate across 54 ports. Key architectural advancements include:

• ​​Port flexibility​​: 28 native 10/25G SFP28 ports + 4 multi-rate 1/10/25G ports + 6 QSFP28 40/100G uplinks + 16 unified ports supporting 10/25G Ethernet or 8/16/32G Fibre Channel
• ​​Cut-through switching​​: Maintains deterministic latency below 2μs even at 100% load
• ​​TAA-compliant hardware​​: Implements FIPS 140-3 Level 2 encryption for management traffic

Certified for ​​NEBS Level 3+​​ and ​​MIL-STD-810G​​ compliance, the chassis integrates ​​Cisco Intersight management​​ with 99.999% control plane availability.

Unified Fabric Capabilities

​​Converged I/O architecture​​ enables simultaneous support for:

1. ​​NVMe-oF over RoCEv2​​: 16M IOPS at 4K block size with 25μs end-to-end latency
2. ​​FCoE consolidation​​: 256 virtual Fibre Channel interfaces per chassis
3. ​​VXLAN/NVGRE offload​​: 1.2M tunnels with hardware-based VTEP termination

Key performance benchmarks:

• ​​400GbE line-rate forwarding​​: Sustains 1.44B pps with 256B packets
• ​​Zero-packet loss failover​​: Achieves sub-50ms convergence during dual-FI outages
• ​​Energy efficiency​​: 0.8W per 10Gbps port under full load

Deployment Scenarios & Compatibility

Third-party integrations require:

• ​​NVIDIA ConnectX-7 adapters​​ for 200G RoCEv2 support
• ​​Pure Storage FlashArray//X​​ for 32G FC SAN boot

Management & Security Features

The chassis implements ​​Cisco TrustSec​​ with:

security-policy hyperscale  
  microsegmentation enable  
  flow-visibility full  
  encryption aes-256-gcm  

​​Key operational insights​​:

• ​​Dynamic power management​​: Automatically scales from 450W (idle) to 1,200W (peak)
• ​​Predictive analytics​​: Detects fan bearing wear 72hrs pre-failure via harmonic analysis
• ​​Firmware rollback​​: Maintains 3 generations of golden images for rapid recovery

Strategic Value in Modern Data Centers

In Tokyo’s 6G mobile core deployments, the chassis demonstrated 97.4% bisection bandwidth utilization during 5G UPF traffic bursts. Its ​​adaptive buffer management​​ dynamically allocated 58% of shared memory to RoCEv2 flows while maintaining 40G FC SAN performance – a 33% improvement over previous-gen FIs.

What truly differentiates this platform isn’t its raw throughput figures, but its ​​holistic approach to infrastructure convergence​​. While competitors struggle with separate management interfaces for LAN/SAN/ML workloads, the UCS-FI-6454-CH’s unified control plane enables true software-defined infrastructure. The ability to reconfigure unified ports from 32G FC to 25G Ethernet in 8 seconds – without physical recabling – redefines operational agility for enterprises navigating hybrid cloud transitions. For organizations prioritizing TCO reduction without compromising performance, this chassis represents the new gold standard in adaptive data center networking.
