Specifications

Description:

Dell S4820T-RA is a high-performance Top-of-Rack (ToR) switch featuring 48x 10GBASE-T (RJ45 copper) ports and 4x 40GbE QSFP+ uplinks, designed for modern data center environments that need high-speed networking over traditional copper infrastructure. With a switching capacity of 1.28 Tbps and forwarding rate of 960 million packets per second (Mpps), it offers enterprise-class performance for demanding workloads. Its MAC address table supports up to 128,000 entries, making it well-suited for high-density virtualized and cloud environments. The switch comes with back-to-front airflow, aligning with hot/cold aisle cooling designs in rack deployments. It supports advanced Layer 2 and Layer 3 routing features, providing a robust and scalable foundation for evolving network architectures.

Features

High-Density Copper Ports: 48x 10GbE RJ45 ports using standard Cat6a/7 cabling — ideal for upgrading server infrastructure without optical transceivers.
Scalable Uplinks: 4x 40GbE QSFP+ ports support high-bandwidth uplinks to spine or aggregation layers.
Enterprise-Class Switching Performance: Up to 1.28 Tbps switching capacity and 960 Mpps throughput ensure smooth traffic flow in performance-sensitive environments.
Layer 2 and Layer 3 Support: Advanced switching and routing capabilities, including static routing, OSPF, BGP, VRF-lite, and multicast.
MAC Table Size: Supports up to 128,000 entries for large deployments and extensive device connectivity.
Optimized Airflow: Back-to-front airflow (PSU to I/O) supports data center thermal efficiency.
