S25N and S50N Data Center Switches

S-Series S25N and S50N High Performance GbE/10 GbE Top-of-Rack Switches

The Dell Force10 S25N and S50N bring core-like resiliency in a compact form factor to the network edge, enabling cost-effective scalability. These high performance
and low latency Gigabit Ethernet switches deliver the critical functionality that advanced data center network edges demand.

Key Applications

Coupled with the Dell Force10 E-Series and C-Series, which deliver unmatched resiliency and performance, the S25N and S50N enable IT managers to deploy a reliable end-to-end 10 GbE solution thats spans from core to network edge.

• Line-rate GbE and 10 GbE rack switches for demanding data center, storage or compute facility
• Cost effective distribution layer into a 10 GbE LAN core or distributed data center deployments

Key Features
