DS-C9148S-12PK9 Cisco MDS 9148S 16G Multilayer Fabric Switch
Cisco DS-C9148S-12PK9 MDS 9148S 16G Multilayer Fabric Switch
High-Performance Cisco MDS 9148S 16G Fibre Channel Switch for Storage Networking
The Cisco DS-C9148S-12PK9 MDS 9000 Series Fabric Switch is a high-performance 16G Fibre Channel SAN switch designed to deliver scalable, low-latency storage networking for enterprise data centers. With a 48-port architecture (12 ports activated by default), it offers a flexible, pay-as-you-grow model that allows organizations to expand port capacity as storage demands increase.
Engineered for reliability and performance, the DS-C9148S-12PK9 provides line-rate Fibre Channel switching with ultra-low latency, ensuring fast and efficient data transfer across storage networks. It supports 2/4/8/16 Gbps Fibre Channel speeds, making it compatible with both legacy and modern storage environments.
Running on Cisco NX-OS, this switch delivers advanced SAN features such as VSAN segmentation, Inter-VSAN Routing (IVR), zoning, and traffic management, enabling secure and optimized storage connectivity. Its credit-based flow control ensures lossless data transport, which is critical for high-performance storage applications.
Designed for high availability, the switch includes redundant hot-swappable power supplies and fan modules, along with support for non-disruptive software upgrades, ensuring continuous operation in mission-critical environments.
Ideal for storage area networks (SAN), data center storage connectivity, backup and disaster recovery systems, the Cisco DS-C9148S-12PK9 provides a scalable, secure, and high-performance foundation for modern storage infrastructures.
