Cisco MDS 9148S Series 48-Port 16 Gigabit (16G) Multilayer Fibre Channel Fabric Switch. Back-to-Front (Power-to-Port) Airflow. P/N: DS-C9148S-K9.

This is a genuine Cisco MDS 9148S Series 48-Port 16 Gigabit (16G) Multilayer Fibre Channel Fabric Switch (P/N: DS-C9148S-K9, 68-5131-02 A0+). Engineered for small to medium-sized data center Storage Area Networks (SANs), this high-performance Fibre Channel switch offers robust, scalable, and highly available connectivity. It provides 48 auto-sensing ports, capable of operating at 4, 8, or 16 Gbps Fibre Channel speeds, ensuring seamless integration with existing SAN infrastructure while supporting future growth. Crucially, the MDS 9148S features Back-to-Front (Power-to-Port) Airflow, meaning cool air is drawn in from the power supply side (typically the hot aisle) and exhausted out the port side (typically the cold aisle). This specific airflow design is critical for integration into data center environments that require this reverse cooling scheme. As a multilayer switch, it combines enterprise-class capabilities with simplified management and cost-effectiveness, delivering advanced features for efficient and secure storage networking.

Key Features 

• 48 x 16Gbps Fibre Channel Ports: Provides 48 high-performance, auto-sensing ports that support 4, 8, and 16 Gbps Fibre Channel speeds, offering flexibility and compatibility with various SAN devices.

• Multilayer Fabric Switch: Combines advanced Fibre Channel switching capabilities with intelligent network services, enabling features like virtual SANs (VSANs), Inter-VSAN Routing (IVR), and comprehensive security.

• Back-to-Front (Power-to-Port) Airflow: Features a reverse airflow design, drawing cool air from the power supply side (back) and exhausting warm air from the port side (front) of the switch. This is essential for specific data center cooling architectures.

• High Performance & Low Latency: Designed to deliver wire-speed performance across all ports with minimal latency, crucial for demanding storage applications.

• Virtual SAN (VSAN) Technology: Allows for the creation of isolated logical SANs over a single physical infrastructure, enhancing security and resource utilization.

• Comprehensive Security: Features include port security, role-based access control (RBAC), Fibre Channel Security Protocol (FC-SP) for authentication, and encryption capabilities.

• Simplified Management: Managed through Cisco Data Center Network Manager (DCNM) or standard command-line interface (CLI), providing intuitive control and automation.

• High Availability: Supports redundant, hot-swappable power supplies and fan trays (typically) to ensure continuous operation and minimize downtime.

• Power Efficient: Engineered with energy-efficient components to reduce operational costs and environmental footprint.

• Compact Form Factor: Typically a 1U rack-mountable design for efficient space utilization in data center racks.
