What Is the DS-C9396V-48EK9?
The DS-C9396V-48EK9 represents Cisco’s evolution of the MDS 9396 Series, offering 48 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 NVMe-oF/TCP protocols. Unlike its predecessor DS-C9396S-48EK9 (16G FC), it delivers 3x higher buffer credits (4,096 vs 1,248) for long-distance FCIP connectivity.
