DS-C9396V-48ITK9P: Cisco\’s Next-Gen 48-Port Storage Switch for AI-Driven SANs, How Does It Outperform MDS 9396S Series in Hyperscale Environments?



What Defines the DS-C9396V-48ITK9P?

The ​​DS-C9396V-48ITK9P​​ represents Cisco’s latest evolution of the ​​MDS 9000 Series​​, delivering ​​48 pre-activated 32G Fibre Channel ports​​ with ​​port-side exhaust design​​. This 2RU switch supports ​​auto-negotiated speeds from 8Gbps to 32Gbps​​, combining backward compatibility with next-gen protocols like ​​NVMe-oF/TCP​​. Unlike its predecessor DS-C9396S-48EK9 (16G FC), it ​​triples buffer credits to 4,096 per port​​ for long-distance FCIP connectivity and doubles VSAN capacity.


Breakthrough Features for Modern Storage Networks

  1. ​Unified Protocol Processing​

    • ​Simultaneous FC/NVMe-oF traffic handling​​ through hardware-accelerated QoS
    • ​Dual-mode SFP+ ports​​ supporting 16G/32G optics without transceiver swaps
    • ​AI-driven load balancing​​ via Cisco DCNM 12+ integration
  2. ​Performance Enhancements​

    • ​32Gbps line-rate throughput​​ with ​​380μs latency​​ (40% improvement over 16G models)
    • ​Dynamic VSAN allocation​​ across ​​8,192 virtual SANs​​ (8x legacy capacity)
    • ​0.08W per Gbps energy efficiency​​ (73% reduction vs 2015-era switches)
  3. ​Military-Grade Reliability​

    • ​Quad redundant 800W PSUs​​ with 94% efficiency
    • ​Sub-second ISSU​​ for zero-downtime upgrades
    • ​Predictive failure analytics​​ for fan/PSU health monitoring

DS-C9396V-48ITK9P vs Legacy Models

Parameter DS-C9396V-48ITK9P (2025) DS-C9396S-48EK9 (2015) Improvement
Base Port Speed ​32Gbps​ 16Gbps 2x Faster
Buffer Credits/Port ​4,096​ 1,248 3.3x Higher
VSAN Capacity ​8,192​ 1,024 8x Scalable
Energy Efficiency 0.08W/Gbps 0.3W/Gbps 73% Savings
Protocol Support ​FC+NVMe/TCP​ FC+FCoE Future-Proof

Strategic Deployment Scenarios

  1. ​AI Training Clusters​
    Sustains ​​250,000+ IOPS​​ per port for distributed NVMe arrays – ​​3x​​ traditional FC switches.

  2. ​Metropolitan SAN Extensions​
    Enables ​​300km FCIP links​​ without signal boosters via enhanced buffer credits.

  3. ​Hybrid Cloud Gateways​
    Provides ​​QoS-prioritized lanes​​ for AWS/Azure/GCP replication.


Procurement & Configuration

For authorized purchases in APAC markets, visit Cisco Certified Store. The DS-C9396V-48ITK9P requires:

  • ​MDS-9396V chassis​​ (included)
  • ​32G SFP56 transceivers​​ (sold separately)
  • ​DCNM Advanced License​​ for AIOps integration

While 64G FC adoption looms, the DS-C9396V-48ITK9P’s ​​mixed-speed port operation​​ and ​​NVMe/TCP convergence​​ make it indispensable for transitional infrastructures. Its true value emerges in environments running ​​legacy FC arrays alongside AI clusters​​ – a reality for 78% of enterprises according to Cisco’s 2025 storage survey. The 32G standard balances performance thresholds with backward compatibility, ensuring ROI protection for existing SAN investments. Organizations prioritizing ​​phased modernization​​ will appreciate its ​​workload-aware zoning​​ that automatically allocates buffer credits based on application criticality, delivering ​​30% CAPEX recovery through energy savings​​ within 24 months.
