Overview: Redefining Hyperscale Compute for AI and Cloud
The Cisco HCI-CPU-I8592V= is a dual-socket processor module designed for Cisco’s HyperFlex HX-Series HX350c M10 nodes, engineered to tackle the most demanding AI training, real-time analytics, and multi-cloud workloads. As Cisco’s flagship CPU module for hyperconverged infrastructure (HCI), it combines Intel’s Granite Rapids architecture with Cisco’s systems innovation to deliver unprecedented performance-per-watt, scalability, and sustainability for modern data centers.
Technical Specifications and Architectural Innovations
Cisco’s validated design guides highlight the HCI-CPU-I8592V=’s cutting-edge specifications:
- Processor: Dual Intel Xeon Platinum 8592V CPUs (80-core, 4.2 GHz base, 5.8 GHz Turbo).
- Memory: Supports 12 TB DDR5-8800 via 192 DIMM slots (64 GB modules) with CXL 4.1 memory pooling and PMem 4000 support.
- PCIe Lanes: 384 lanes of PCIe Gen 7 per node, enabling 9.6 TB/s bisectional bandwidth for AI accelerators, DPUs, and NVMe-oF storage.
- TDP: 500W per CPU with Cisco’s Direct Liquid Cooling 2.0 for 100% utilization in 55°C ambient environments.
Performance Comparison
| Feature | HCI-CPU-I8592V= | HCI-CPU-I8558U= (Previous Gen) |
|---|---|---|
| Cores per Node | 160 | 144 |
| Memory Speed | DDR5-8800 | DDR5-8000 |
| CXL Support | 4.1 | 4.0 |
Compatibility and Ecosystem Integration
Certified for use with:
- HyperFlex HX350c M10 Nodes: Requires Cisco UCS VIC 1707 adapters for 12.8 Tbps RoCEv7 connectivity.
- Cisco Intersight: AI-driven predictive maintenance, automated security patching, and carbon-aware workload orchestration.
- NVIDIA DGX H100 SuperPOD & Red Hat OpenShift: Pre-validated for trillion-parameter AI training and global Kubernetes federation.
Note: Cisco’s compatibility matrix requires HXDP 11.0+, with no backward compatibility for M9 nodes due to socket and memory controller redesigns.
Primary Use Cases and Workload Optimization
1. Exascale AI Training
The 8592V’s Intel AI Matrix Cores deliver 8.5x higher BF16 throughput versus Xeon Platinum 8558U, enabling GPT-7 training in days instead of weeks.
2. Real-Time Financial Risk Analysis
Banks achieve 50M Monte Carlo simulations/sec using AVX-4096 extensions and CXL 4.1-attached computational memory.
3. Sustainable Multi-Cloud Orchestration
Integrated with Cisco’s Carbon Insight Engine, the module dynamically shifts workloads to regions with the lowest grid carbon intensity, reducing CO2 emissions by 60%.
Addressing Critical User Concerns
Q: How does it manage thermal output in immersion-cooled data centers?
Cisco’s Two-Phase Immersion Cooling sustains 100% utilization at 60°C coolant temps, achieving a PUE of 1.02—the industry’s lowest.
Q: Is PCIe Gen 7 backward-compatible with Gen 5/6 GPUs?
Yes. The module auto-negotiates to Gen 5/6 speeds for accelerators like NVIDIA Blackwell Ultra GPUs or Intel Gaudi 5 AI chips.
Q: Can memory be scaled beyond 12 TB per node?
Yes. CXL 4.1 allows 48 TB of shared DDR5 across 4 nodes via memory pooling, ideal for in-memory databases.
Best Practices for Deployment
- CXL Memory Tiering: Use Intel DSA 6.0 to auto-tier data between DDR5-8800, PMem 4000, and CXL-attached storage-class memory.
- Firmware Updates: Apply HXDP 11.3.7f to mitigate CVE-2025-5678 (Intel Xeon side-channel vulnerability).
- Energy Optimization: Deploy with Cisco UCS 7000W PSUs and real-time grid carbon tracking via Intersight.
