4JT2K - Dell EMC PowerSwitch S6010-ON 32-Port 40GbE Switch

Dell EMC 4JT2K S6010-ON is a 1U, 32-port 40GbE QSFP+ Layer 2/3 open networking switch built for high-density, low-latency data center and ToR deployments.

The Dell EMC 4JT2K, also known by its model designation S6010-ON, is a 1U rack-mountable, open networking Ethernet switch belonging to Dell's PowerSwitch S6000 Series. It provides 32 fixed 40 Gigabit Ethernet QSFP+ ports supporting Layer 2 and Layer 3 switching, making it well suited for top-of-rack (ToR) deployment in modern data centers, cloud environments, and high-performance computing clusters. As part of Dell's disaggregated hardware-and-software networking strategy, the S6010-ON allows organizations to choose from multiple network operating systems, enabling flexible fabric orchestration and automation. It offers a 2.56Tbps full-duplex switching fabric, a forwarding rate up to 1462Mpps, and sub-600ns latency, along with a 160K MAC address table for large-scale environments. The switch is commonly used in virtualization, storage convergence (RoCE/iSCSI), and cloud computing infrastructures, and is typically sold as a refurbished unit through certified networking resellers.
