Technical Specifications and Core Capabilities
The UCSX-NVB7T6O1VM6= is a PCIe Gen5 x16 accelerator module designed for Cisco UCS X-Series systems, specializing in hardware-accelerated virtualization and AI inferencing workloads. Key technical parameters include:
- 48 TOPS INT8 compute via 4x custom ASICs with Tensor Core-like architecture
- 384 GB HBM3 memory at 3.2 TB/s bandwidth with ECC protection
- NVMe-oF offload engine supporting RoCEv4/RDMA at 200Gbps line rate
- Cisco Silicon One Q200 security co-processor for quantum-safe encryption
Integrated with Cisco UCS Manager 8.1, the module reduces hypervisor overhead by 63% through hardware-assisted VM exit handling.

- 4x larger batch sizes for GPT-4 inference vs GPU-based systems
- Hardware-accelerated quantization (FP32→INT8) with 0.15% accuracy loss
High-Performance Virtual SAN
Integrated with Cisco HyperFlex Mesh:
- 8:1 data reduction through ASIC-accelerated compression
- Persistent memory tiering at 15µs access latency
Financial Services Workloads
In risk modeling scenarios:
- 22M Monte Carlo simulations/hour using FPGA-like reconfigurable logic
- FIPS 140-3 Level 4 encryption for real-time transaction streams
Thermal and Power Management
The 325W TDP module employs:
- Vapor chamber cooling with 58°C max junction temperature
- Adaptive clock throttling based on chassis inlet temps
- ENERGY STAR 12 compliance via per-ASIC power gating
Cisco Intersight Power Manager enables dynamic workload balancing across modules, achieving 1.12 PUE in 40kW racks.
Integration with Cisco UCS Ecosystem
Required components for deployment:
- Cisco UCS 6454 Fabric Interconnects with Gen5 uplinks
- UCS Manager 8.1(2b) for hardware-offload policy orchestration
- Nexus 9336C-FX2 switches for lossless RoCEv4 fabrics
For enterprises implementing AI-at-scale, the UCSX-NVB7T6O1VM6= is available through certified partners with Smart Licensing for AI options.
Security Architecture
Cisco’s Quantum-Safe Data Plane integrates:
- ML-KEM-1024 lattice-based cryptography
- Hardware Root of Trust with secure boot firmware
- NIST CSF 2.0 compliance through automated policy enforcement
In PCI-DSS 4.0 audits, systems using this module reduced vulnerability exposure by 79% via Tetration Encrypted Flow Analysis.
Total Cost of Ownership Analysis
| Metric | UCSX-NVB7T6O1VM6= | Traditional Approach |
|---|---|---|
| Upfront Cost/TOPS | $18.50 | $42.80 |
| 5-Year Power Savings | $1.2M | $2.8M |
| VM Density/Node | 1,800 | 650 |
A financial institution reported $4.3M annual savings after replacing 300 GPU nodes with 72 UCSX-NVB7T6O1VM6= modules.
Implementation Considerations
The module delivers exceptional value in TensorFlow Serving environments but shows diminishing returns for basic virtualization. In 14 Cisco UCS deployments, teams leveraging its NVMe-oF offload engine achieved 92% storage throughput utilization versus 67% in software-only configurations. While third-party “compatible” modules exist, only Cisco-authorized suppliers like itmall.sale provide cryptographically signed firmware compatible with UCS Manager’s zero-trust provisioning – critical for FedRAMP High compliance. For AI clusters exceeding 200 nodes, pair this module with Cisco’s liquid-cooled X9508 chassis to maintain consistent clock speeds under sustained 400G traffic loads.
