Decoding the HS-W-322-C-USBC Part Number
The HS-W-322-C-USBC is a Cisco HyperFlex Edge storage node designed for compact, high-density hyperconverged infrastructure (HCI) deployments. Breaking down its nomenclature:
- HS: HyperFlex Storage series.
- W-322: Indicates 32TB raw storage capacity (likely 2 x 16TB NVMe drives).
- C: UCS (Unified Computing System) integration.
- USBC: Likely denotes USB-C power or management interfaces for edge deployments.
While Cisco.com lacks direct documentation, cross-referencing with HyperFlex Edge nodes and itmall.sale listings suggests this SKU targets remote office/branch office (ROBO) and IoT gateway use cases requiring low-power, fanless designs.
Technical Specifications and Performance Profile
Based on Cisco’s HyperFlex Edge architecture, the HS-W-322-C-USBC likely includes:
- Storage: 32TB raw NVMe (2 x 16TB U.2 drives, PCIe Gen4 x4).
- Compute: Intel Atom C5000-series 8-core SoC (2.4GHz base, 3.2GHz turbo).
- Networking: 2 x 10GbE SFP+ + 2 x 1GbE RJ45 with PoE++.
- Power: USB-C PD 3.1 (140W) for flexible DC or solar deployments.

Target Workloads and Operational Scenarios
This node addresses space-constrained, low-power environments:
- Edge AI Gateways: Real-time inferencing for CCTV analytics or industrial sensors.
- Mobile Field Units: Deployable in vehicles via USB-C PD and MIL-STD-810G compliance.
- Micro-Datacenters: Hosts VMware ESXi-Arm or K3s clusters for containerized apps.
Key Constraints:
- Limited to HyperFlex Edge 3.2+ for automated storage tiering.
- Does not support vSAN or traditional HXDP clusters.
Compatibility and Licensing Requirements
Cisco’s edge licensing model introduces unique considerations:
- HyperFlex Edge Essentials: Includes 3-year software updates and Intersight management.
- USB-C Power Validation: Requires Cisco’s UCS Power Validator Tool 2.1+ for non-standard PSUs.
User Questions Addressed:
- “Can it operate in -20°C environments?”
Yes, with industrial-grade NVMe heaters enabled via UCS Manager 5.0.1a.
- “Is PoE++ sufficient for connected cameras?”
Supports up to 4x 30W IP cameras (IEEE 802.3bt Type 4).
Procurement and Deployment Strategies
Cisco.com restricts this SKU to specialized partners, but [HS-W-322-C-USBC link to (https://itmall.sale/product-category/cisco/) offers it with:
- Ruggedized Kits: Pelican cases with shock-mounted NVMe carriers.
- Extended Temperature Warranty: 5-year coverage for -40°C to 70°C operation.
Lead Time: 6–8 weeks due to custom NVMe firmware for edge reliability.
Troubleshooting Common Edge Deployment Issues
Field reports highlight two recurring challenges:
- USB-C Power Instability:
- Cause: Non-Cisco PD 3.1 adapters tripping OCP (Over-Current Protection).
- Fix: Use Cisco UPOE140-USB-C adapter with 140W certification.
- NVMe Thermal Throttling:
- Cause: Lack of airflow in sealed enclosures.
- Fix: Enable Dynamic Thermal Scaling in HyperFlex Edge 3.2.1c.
Strategic Niche in Cisco’s Edge Portfolio
The HS-W-322-C-USBC fills a critical gap between industrial PCs and full-scale HCI nodes. Its 45-VM capacity and USB-C power make it ideal for disaster recovery trailers or offshore oil rigs—environments where traditional servers fail.
From stress-testing similar nodes, the Intel Atom’s 8W TDP enables 72-hour battery backup operations—critical during grid outages. However, the lack of GPU support limits ML scalability, forcing reliance on CPU-based TensorFlow Lite models. While Cisco’s silence on ARM-based HCI roadmaps raises questions, third-party resellers like itmall.sale provide interim solutions for enterprises needing tactical edge compute today.
