What Is the Cisco RHEL-VDC-2SUV-1A=?
The Cisco RHEL-VDC-2SUV-1A= is a virtualization-optimized hardware and software bundle designed for enterprises deploying Red Hat Enterprise Linux (RHEL) workloads on Cisco UCS® platforms. This validated solution combines Cisco’s UCS C220 M6 rack server with pre-configured RHEL entitlements, providing a turnkey infrastructure for hybrid cloud, AI/ML, and enterprise application hosting.
Key components include:
- Cisco UCS C220 M6 Server: Dual Intel® Xeon® Scalable processors, 24x DDR4 DIMM slots, and 12x NVMe/SATA drive bays.
- Red Hat Enterprise Linux 8.5+: Pre-installed with Smart Virtualization (VIRT) and Smart Management entitlements.
- Cisco Intersight Integration: Enables centralized lifecycle management for distributed deployments.
Technical Specifications and Compatibility
The RHEL-VDC-2SUV-1A= is engineered for performance-intensive virtualized environments. Below are its critical specifications:
| Parameter | Value |
|---|---|

| Memory | 256GB DDR4-3200 (8x32GB) |
| Storage | 8x 1.92TB NVMe SSD (RAID 10) |
| Networking | 2x 25G SFP28 (Cisco VIC 1457) |
| Power Supply | 2x 500W Platinum (1+1 redundancy) |
| Supported Hypervisors | RHEL KVM, VMware vSphere 7.0+ |
Software Stack:
- Red Hat Ansible Automation Platform 2.2+
- Cisco UCS Manager 4.2+
- Red Hat OpenShift Container Platform 4.10+ (optional)
Primary Use Cases and Deployment Scenarios
1. Hybrid Cloud Workload Portability
The bundle supports seamless migration of RHEL VMs between on-prem UCS clusters and public clouds (AWS, Azure) via Red Hat Cloud Access. For example, a financial institution replicated its risk modeling VMs to Azure during peak loads, reducing on-prem CAPEX by 30%.
2. AI/ML Training Clusters
With NVIDIA A100 GPU passthrough (via Cisco UCS PCIe FlexStorage), the solution accelerates distributed training tasks like NLP model fine-tuning, achieving 90% GPU utilization.
3. Telco Edge Virtualization
Telecom operators deploy the RHEL-VDC-2SUV-1A= in 5G MEC (Multi-Access Edge Computing) sites to host virtualized RAN (vRAN) and network slicing controllers, achieving <10ms latency for URLLC services.
Installation and Configuration Best Practices
Hardware Provisioning
- RAID Configuration: Use Cisco UCS CIMC to set RAID 10 for NVMe SSDs, ensuring IOPS >500k for database workloads.
- GPU Installation: Mount GPUs in slots 3–4 to leverage direct CPU connectivity, avoiding PCIe switch latency.
Software Optimization
- KVM Tuning: Allocate CPU cores exclusively to VMs using

Troubleshooting Common Issues
- VM Boot Failure: Check for Secure Boot conflicts in UEFI settings.
- Storage Latency Spikes: Monitor NVMe wear levels with
smartctl -a /dev/nvme0n1.
Why Choose RHEL-VDC-2SUV-1A= Over DIY Solutions?
While assembling servers and licenses independently may save 10–15% upfront, Cisco’s validated solution offers:
- Single-Vendor Support: Joint TAC cases resolve cross-layer issues 50% faster.
- Cisco HyperFlex Integration: Extend storage clusters without reconfiguring RHEL LVM.
- FIPS 140-2 Compliance: Pre-hardened for government/defense workloads.

Lessons from Enterprise Deployments
During a global retail chain’s POS system upgrade, the RHEL-VDC-2SUV-1A= reduced VM provisioning time from 4 hours to 15 minutes via Ansible-driven automation. However, the deployment uncovered a critical oversight: the team initially under-provisioned RAM, forcing costly mid-project upgrades. Contrast this with a competitor’s DIY approach using white-box servers—they faced 3 weeks of downtime due to driver incompatibilities between RHEL 8.5 and older NICs. For architects, the choice is clear: validated stacks mitigate risks that DIY setups merely outsource to IT teams.
