High-performance open networking top-of-rack switches with multirate Gigabit Ethernet
and unied ports
The S4100-ON 10GbE switches comprise Dell EMC’s latest disaggregated hardware and software data center networking solutions,
providing state-of-the-art 100GbE uplinks, bre channel connectivity
and a broad range of functionality to meet the growing demands of
today’s data center environment. These innovative, next-generation
top-of-rack open networking switches oer optimum exibility and
cost-eectiveness for the enterprise, mid-market and Tier2 cloud
service provider with demanding compute and storage trac environments.
The compact S4100-ON models provide industry-leading density
with up to 48 ports of 10GbE or up to 48 ports of 10GBaseT ports,
2 ports of 40GbE and 4 ports of 100GbE in a 1RU form factor. The
S4148U-ON model can support up to 28 8/16G bre channel ports,
or 16 ports of 32G* bre channel ports. The S4112-ON is a halfrack width model that supports up to 12 ports of 10GbE or 12 ports
10GBaseT, and 3 ports of 100GbE.
Using industry-leading hardware and a choice of Dell EMC’s OS10 or
select 3rd party network operating systems and tools, the S4100-ON
Series oers exibility by provision of conguration proles and delivers non-blocking performance for workloads sensitive to packet loss.
The compact S4100-ON models provide multirate speed, enabling
denser footprints and simplifying migration to 100Gbps.
Also unique to the S4100-ON series is the ability to meet the
demands of converged and virtualized data centers by oering
unied ports (S4148U) and hardware support for L2 and L3 VXLAN
Gateway. Priority-based ow control (PFC), data center bridge
exchange (DCBX) and enhanced transmission selection (ETS) make
the S4100-ON ideally suited for DCB environments.
Dell Networking S4100-ON switches support the open source Open
Network Install Environment (ONIE) for zero touch installation of Dell
EMC’s OS10 networking operating system, as well as of alternative
network operating systems.
Maximum performance and functionality
The S4100-ON series are high-performance, multi-function,
1/10/25/40/50/100 GbE and 8/16/32G FC Top-of-Rack (ToR)
switches purpose-built for applications in high-performance data
center, cloud and computing environments.
Architectural features to optimize data center network exibility,
eciency and availability include IO panel to PSU airow or PSU
to IO panel airow for hot/cold aisle environments and redundant,
hot-swappable power supplies and fans.
