Dell introduced a new X-Series family of smart-managed 1GbE and 10GbE switches for small and medium-sized businesses. The new product provide work flow management, traffic visibility and real-time control to optimize cloud and onsite network applications. Dell is also expanding its N-Series family of fully managed 1GbE switches with Layer 2/3 capability designed for smaller networks. The switches utilize a comprehensive enterprise-class Layer 2/3 feature set, common command-line interface (CLI) for consistent management and standard 10GbE SFP+ transceivers and cables for stacking, providing up to 200 1GbE ports in a 4-unit stack.
