Description
The Dell EMC PowerSwitch S4048T-ON (identified by SKU S4048-ON-F2B) is a high-performance, low-latency network switch engineered for modern data center deployments. It is designed to serve as a Top-of-Rack (ToR) switch, providing high-density connectivity for servers and storage devices. The switch features 48 ports capable of 10 Gigabit Ethernet (10GbE) using SFP+ transceivers, and six ports capable of 40 Gigabit Ethernet (40GbE) using QSFP+ transceivers. This combination offers significant bandwidth and flexibility for demanding network environments. With a switching capacity of 1.28 Terabits per second (Tbps) and a forwarding rate of 960 million packets per second (Mpps), the S4048T-ON can handle large volumes of traffic efficiently. Its sub-microsecond latency makes it ideal for performance-sensitive applications such as high-frequency trading, big data analytics, and high-performance computing (HPC) clusters. The 'ON' (Open Networking) designation signifies its support for open network operating systems, allowing organizations to choose the software that best fits their operational needs and automation strategies, such as Dell's SmartFabric OS or other compatible NOS solutions. The S4048T-ON is built for reliability and scalability in data center environments. It typically supports features like redundant power supplies and fans, advanced Quality of Service (QoS) capabilities, and robust security features. Its high port density and performance characteristics make it a versatile solution for network aggregation, server access, and building scalable, high-performance data center fabrics.
