Dell Networking S55 Specifications

Dell Networking S Series
S55 high-performance 1/10GbE top-of-rack switch
48-port GbE switch with up to four modular 10GbE ports or stacking interfaces in just 1RU, non-blocking
architecture supports low-latency switching and routing, integrated network automation and
virtualization technology with Networking's Open Automation Framework, reliable, data center optimized
design supports I/O-to-PSU and PSU-to-I/O airflows and redundant, hot-swappable power.
Data center optimized 1/10GbE switch
The Dell Networking S Series S55 1/10GbE top-of-rack
(ToR) switch is optimized for lowering operational costs
while increasing scalability and improving manageability
at the network edge. Optimized for high-performance
data center applications, the S55 leverages a non-blocking
architecture that delivers low-latency L2 and L3 switching
to eliminate network bottlenecks. The high-density S55
design provides 48 GbE access ports with up to four
modular 10GbE uplinks in just 1RU to conserve valuable
rack space. The S55 incorporates multiple architectural
features that optimize data center network efficiency and
reliability, including I/O-to-PSU panel airflow or PSU-
to-I/O panel airflow for hot/cold aisle environments,
and redundant, hot-swappable power supplies and
fans. A "scale-as-you-grow" ToR solution that is simple
to deploy and manage, up to 12 S55 switches can be
stacked to create a a single logical switch by utilizing
Dell Networking's stacking technology and high-speed
stacking modules.
The S55 provides support for Dell Networking's Open
Automation Framework, which leverages capabilities
of the modular Dell FTOS software to bring network
automation into virtual data center environments, making
them more responsive and able to adapt to changes
in application requirements. The Open Automation
Framework is comprised of a suite of inter-related
network management tools that can be used together or
independently to provide a network that is more flexible,
available and manageable while reducing operational
expenses.
Applications
• 1/10GbE server aggregation at the ToR in high-
performance data center environments
