Overview:
48-port GbE switch with up to four modular 10 GbE ports or stacking interfaces in just 1-RU; non-blocking architecture supports line-rate, low-latency switching and routing; integrated network automation and virtualization technology with Networking’s Open Automation Framework; reliable, data center optimized design supports front-to-back airflow and redundant, hot-swappable power.
Data center optimized 1/10 GbE switch
The Dell Networking S-Series S55 1/10 GbE ToR (Top-of-Rack) switch is optimized for lowering operational costs while increasing scalability and improving manageability at the network edge. Optimized for high-performance data center applications, the S55 leverages a non-blocking architecture that delivers line-rate, low-latency L2 and L3 switching to eliminate network bottlenecks. The high-density S55 design provides 48 GbE access ports with up to four modular 10 GbE uplinks in just 1-RU to conserve valuable rack space. The S55 incorporates multiple architectural features that optimize data center network efficiency and reliability, including IO panel to PSU airflow or PSU to IO panel airflow for hot/cold aisle environments, and redundant, hot-swappable power supplies and fans. A “scale-as-you-grow” ToR solution that is simple to deploy and manage, up to 8 S55 switches can be stacked to create a a single logical switch by utilizing Dell Networking’s stacking technology and high-speed stacking modules.
The S55 provides support for Dell Networking’s Open Automation Framework, which leverages capabilities of the modular Dell Networking Operating System (FTOS) software to bring network automation into virtual data center environments, making them more responsive and able to adapt to changes in application requirements. The Open Automation Framework is comprised of a suite of inter-related network management tools that can be used together or independently to provide a network that is more flexible, available and manageable while reducing operational expenses.
