product information
Designed for virtualized data center and cloud environments, the Allied Telesis AT-DC2552XS
switch provides high density 10GbE and 40GbE connectivity, making it ideal for today’s mini and
small data centers, which use up to hundreds of server ports.
The Allied Telesis AT-DC2552XS is a 48
x 10GbE (SFP+) port high-bandwidth
and high-density switch designed for
data center applications. It also provides
four QSFP+ 40GbE slots for “fat-pipe”
high bandwidth uplinks. This switch
delivers 1280Gbps of switching fabric
with ultra low sub-μsec latency. Airow
has been optimized for front-to-back
cooling for data center environments.
The unit can also accommodate a 1+1
resilient power supply, along with these
specications, in a very compact 1RU
unit chassis.
A smarter data center can be achieved
by connecting servers and storage
facilities with a high-speed and low
latency network fabric that is faster,
greener, open, and easy to manage.
Advanced Energy Efciency
Energy efcient architecture and
front-to-back air-ow cooling of the
AT-DC2552XS are critical factors in
optimizing data center economics—as
companies must balance performance
with power consumption to meet
energy budgets.
High-bandwidth
As bandwidth-intensive applications—
such as Web 2.0, virtualization, High-
Performance Computing (HPC) and
Network Attached Storage (NAS)—
continue to proliferate within enterprise
data centers, 10 Gigabit Ethernet
(10GbE) provides a cost-effective way
to increase throughput and seamlessly
deliver customer Service Level
Agreements.
Future Proong
10GbE empowers companies to
expand application capabilities, reduce
time to solve complex nancial and
scientic applications, and quickly
respond to changing customer needs
and market conditions.
In combination with the AT-VNC10S
Network Interface Cards for servers, it
helps clients to reduce the use of I/O
adapters, reducing costs and complexity.
High Availability
The AT-DC2552XS has two slots for
hot-swappable PSUs (Power Supply
Unit) and fans. In addition, SFP+ and
QSFP modules can be easily removed
and replaced with no interruption to the
network. These hot-swappable modules
guarantee the continued delivery of
essential services.
Cut-through
Cut-through switching sends packets
to their destination as soon as the
rst part is ready. The delay is minimal
and the packet reaches its destination
in the shortest possible time. With
cut-through mode, the AT-DC2552XS
forwards packets with a latency of
505 nanoseconds with 40Gb / 800
nanoseconds with 10Gb and is ideal for
inter-server communication.
Air Flow
Cooling air ow has become a major
design concern in modern data centers.
The AT-DC2552XS utilizes front (PSU
and fan side) to back (ports side) airow,
which is suitable for rack mounting in
data centers.
Eco-friendly
In keeping with our commitment to
environmentally
friendly products, this
switch is designed
to reduce power consumption and
minimize hazardous waste.
