Dell Networking S3048-ON
1GbE top-of-rack open networking switch
High density 1000BASE-T switch
The Dell Networking S3048-ON 1000BASE-T Top-of-Rack
(ToR) switch is the industry’s rst 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), such as Cumulus Linux.
This open networking platform is built for highperformance, software-dened data centers and provides
the features to run traditional workloads and the exibility
to deploy new workloads such as Hadoop, SDS and
Big Data. The S3048-ON oers the exibility to run OS
options optimized for diverse deployment needs on a
common hardware platform and architecture.
The S3048-ON features a non-blocking switching
architecture coupled with OS9.X software, delivering
line-rate L2/L3 features for maximized network
performance. The S3048-ON design provides (48)
1000BASE-T ports that support 10MbE/100MbE/1GbE and
four 10GbE SFP+ uplinks. Each 10GbE interface can be
used as uplinks to the network spine/core, as stack ports
to connect up to six units in a stacked conguration, or a
combination of both, depending on network architecture
and uplink/stack bandwidth requirements.
The S3048-ON incorporates multiple architectural
features that optimize data center network exibility,
eciency and availability. including:
• I/O panel to PSU airow or PSU to I/O panel airow for
hot/cold aisle environments
• Redundant, hot-swappable power supplies and fans
with color coded touch points for ease of identication/
removal.
• Dell ReadyRails for ecient installation of the switch
into data center cabinets.
The S3048-ON also supports Dell Networking’s
Embedded Open Automation Framework, which
provides advanced network automation and virtualization
capabilities for virtual data center environments.
Embedded Open Automation Framework is a suite of
network management apps that can be used together
or independently to provide a network that is exible,
available and manageable while helping to reduce
operational expenses.
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
netw ork architecture
• Enterprise, Web 2.0 and cloud service providers’ data cen-
ter networks for ToR applications
• High-performance SDN/OpenFlow 1.3 enabled with
ability to inter-operate with industry standard OpenFlow
controllers
Key features
• Four SFP+ 10GbE ports for maximum flexibility and
invest ment protection
• I/O panel to PSU airow or PSU to I/O panel airow
• Redundant, hot-swappable power supplies and fans
• Supports ONIE for zero-touch installation of alternate
network operating systems
• Open Networking oers choice of OS, such as Dell
Networking OS9.X for inherent stability and feature
richness, or the exibility of a third-part OS (such as
Cumulus Linux)
• VRF-lite enables sharing of networking infrastructure and
provides L3 trac 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 conguration and provisioning
capabilities to simplify the management of virtual
network environments
