High density 1000BASE-T switch 

The Dell PowerSwitch S3048-ON 1000BASE-T top-ofrack (ToR) switch is the industry’s first 1GbE enterprise switching platform to deliver both an industry hardened OS and support for open networking, providing freedom to run third-party operating systems (OS).

Key applications: 

• High-density 1000BASE-T ToR server aggregation in high-performance data centers environments

• Active Fabric™ designs with the S- or Z-Series core switch to create a two tier, 1/10/40GbE data center network architecture

• Enterprise, Web 2.0 and cloud service providers’ data center networks for ToR applications

• High-performance SDN/OpenFlow 1.3 enabled with ability to inter-operate with industry standard OpenFlow controllers

Key features:

• Scalable L2 and L3 Ethernet switching with QoS and a full complement of standards-based IPv4 and IPv6 features, including OSPF, BGP and PBR (Policy Based Routing) support

• Four SFP+ 10GbE ports for maximum flexibility and investment protection

• I/O panel to PSU airflow or PSU to I/O panel airflow

• Redundant, hot-swappable power supplies and fans

• Supports ONIE for zero-touch installation of alternate network operating systems

• Open Networking offers choice of OS, such as Dell SmartFabric OS10 and Dell OS9, for inherent stability and feature richness, or      the flexibility of a third-party OS

• VRF-lite enables sharing of networking infrastructure and provides L3 traffic isolation across tenants (including support for                
  multicast and IPv6 routing)

• Enhanced automation capabilities (puppet agent, REST API extensions)

• Supports jumbo frames for high-end performance in virtualized environments and IP storage/server communication

• Increase VM Mobility region by stretching L2 VLAN within or across two DCs with unique VLT capabilities like Routed VLT, VLT          Proxy Gateway

• User port stacking support for up to six units managed as one logical device

• Embedded Open Automation Framework adds VM awareness automated configuration and provisioning capabilities to simplify the    management of virtual network environments
