DS-C9148S-D12P8K9 Cisco MDS 9148S 16G Multilayer Fabric Switch
High-Density 16-Gbps Fibre Channel Switch with Advanced SAN Analytics and Scalability
The Cisco MDS 9148S 16Gb Fibre Channel Switch (DS-C9148S-D12P8K9) is a high-performance, enterprise-grade SAN switching solution designed for small to mid-sized data centers running mission-critical storage workloads. Combining high port density, ultra-low latency, and advanced SAN services, the MDS 9148S delivers reliable, scalable Fibre Channel connectivity in a compact 1RU form factor.
The switch supports up to 48 autosensing 16-Gbps Fibre Channel ports, with a pay-as-you-grow licensing model that activates 12 ports by default and allows seamless expansion as storage requirements grow. With 768 Gbps switching bandwidth, 384 Mpps forwarding rate, and sub-microsecond port-to-port latency, the Cisco MDS 9148S ensures predictable performance for latency-sensitive applications such as databases, virtualization, and enterprise storage arrays.
Built on Cisco NX-OS for SAN, the MDS 9148S provides advanced storage networking features including Virtual SANs (VSANs), Inter-VSAN Routing (IVR), and hardware-based intelligent zoning for secure traffic segmentation. Enhanced virtualization support - such as NPIV, NPV, and tight VMware vCenter integration - makes it ideal for modern virtualized data centers.
Enterprise-class reliability is delivered through redundant hot-swappable power supplies and fans, extensive buffer credits (up to 4096) for long-distance Fibre Channel links, and integrated analytics for real-time monitoring and telemetry. Strong security features, including RBAC, secure boot, digitally signed firmware, and FIPS 140-2 compliance (with appropriate modules), help meet regulatory and compliance requirements.
Compatible with Cisco MDS 9700, 9200, and 9100 series, as well as third-party Fibre Channel devices and Cisco UCS, the Cisco MDS 9148S is an ideal choice for organizations seeking a scalable, secure, and high-performance 16G Fibre Channel SAN switch.
