What Is the DS-C9124V-8PIVK9?
The DS-C9124V-8PIVK9 is a port activation license for Cisco MDS 9124V multilayer fabric switches, designed to scale Fibre Channel SAN infrastructures from 8 to 24 ports through field-upgradable licensing. This license supports mixed-speed configurations (4/8/16/32G) and integrates with Cisco NX-OS SAN-OS software to reduce cabling complexity by 50% in high-density storage environments.
Key Technical Specifications
1. Dynamic Port Activation
- Activates 8 ports per license with non-disruptive scalability
- Supports auto-sensing SFP+ modules and <500ns latency
- Maintains stateful process restart during supervisor failover
2. Power & Thermal Efficiency
- 28W/port optimized cooling at 55°C ambient temperature
- Dual 400W N+1 redundant power supplies
- Compatible with Cisco EnergyWise for 30% power savings
3. Security & Compliance

Performance Comparison: DS-C9124V-8PIVK9 vs Fixed-Port SAN Switches
| Metric | MDS 9148 (Fixed 48-Port) | DS-C9124V-8PIVK9 Activated |
|---|---|---|
| Initial CAPEX | $57,000+ | 40% reduction with base 8 ports |
| Mixed-Speed Support | 16G/32G only | 4G to 32G auto-negotiation |
| Encryption Throughput | 2.4M IOPS | 4.8M IOPS with MACsec-256 |
| Energy Efficiency | 1.8W/Gbps | 0.9W/Gbps optimized ASICs |
Implementation Strategies
Q: How to integrate with Cisco UCS C4800 ML servers?
A: The license enables Inter-VSAN Routing (IVR) through NX-OS 9.3+, synchronizing QoS policies between MDS 9124V switches and UCS domains via Cisco DCNM. For VMware vSAN deployments, it maintains <2ms latency through FCoE gateway functionality.
Q: What maintenance optimizes performance?
- Replace N+1 fans every 3 years
- Monitor optical rx power to prevent signal degradation below -15dBm
- License upgrades available through Cisco’s authorized portal
The DS-C9124V-8PIVK9 redefines pay-as-you-grow SAN economics, enabling 23μs consistent latency for AI/ML training clusters accessing distributed NVMe arrays. Its adaptive zoning automatically quarantines misconfigured storage nodes, critical for HIPAA-compliant medical imaging archives. Enterprises transitioning to 32G FC infrastructure should prioritize this model for eliminating hardware refresh cycles through non-disruptive speed upgrades. Procurement validation should be coordinated through the Cisco hardware marketplace to ensure compatibility with NetApp FAS/E-Series or Dell PowerStore arrays.
Cisco’s software-defined SAN evolution achieves full expression here—port capacity becomes a consumable resource rather than fixed hardware. The license’s 55°C ambient tolerance and predictive failure analysis via DCNM machine learning models make it indispensable for edge compute nodes in automated manufacturing.
