DELL EMC NETWORKING S4048ON SWITCH

10/40GbE top-of-rack open networking switch

The Dell EMC Networking S4048-ON switch empowers organizations to
deploy workloads and applications designed for the open networking era.

Businesses who have made the transition away from monolithic
proprietary mainframe systems to industry standard server platforms can
now enjoy even greater benets from Dell open networking platforms.
Using industry-leading hardware and a choice of leading network
operating systems to simplify data center fabric orchestration and
automation, organizations can accelerate innovation by tailoring their
network to their unique requirements.

These new oerings provide the needed exibility to transform data
centers. High-capacity network fabrics that are cost-eective and easy
to deploy provide a clear path to a software-dened data center of the
future, as well as freedom from vendor lock-in.

The Dell EMC S4048-ON supports the open source Open Network Install
Environment (ONIE) for zero-touch installation of alternate network
operating systems including feature-rich Dell Networking OS.

Ultra-low-latency, data center optimized

The Dell EMC Networking S-Series S4048-ON is an ultra-low-latency
10/40GbE top-of-rack (ToR) switch built for applications in high­performance data center and computing environments. Leveraging a
non-blocking switching architecture, the S4048-ON delivers line-rate L2
and L3 forwarding capacity with ultra-low-latency to maximize network
performance. The compact S4048-ON design provides industry-leading
density of 48 dual-speed 1/10GbE (SFP+) ports as well as six 40GbE
QSFP+ uplinks to conserve valuable rack space and simplify the migration
to 40Gbps in the data center core (each 40GbE QSFP+ uplink can also
support four 10GbE ports with a breakout cable). In addition, the S4048­ON incorporates multiple architectural features that optimize data center
network exibility, eciency and availability, including I/O panel to PSU
airow or PSU to I/O panel airow for hot/cold aisle environments, and
redundant, hot-swappable power supplies and fans.

S4048-ON supports feature-rich Dell Networking OS, VLT, network
virtualization features such as VRF-lite, VXLAN Gateway and support for
Dell Embedded Open Automation Framework.

• The S4048-ON is the only switch in the industry that provides
customers an unbiased approach to Network Virtualization by
supporting both network-centric virtualization method (VRF-lite)
and Hypervisor centric virtualization method (VXLAN).

• The S4048-ON also supports Dell Networking’s Embedded
Open Automation Framework, which provides enhanced network
automation and virtualization capabilities for virtual data center
environments.

• The Open Automation Framework comprises a suite of interrelated
network management tools that can be used together or
independently to provide a network that is exible, available and
manageable while helping to reduce operational expenses.
