AT-DC2552XS

HIGH PERFORMANCE, LOW LATENCY

TOP-OF-RACK DATA CENTER SWITCH

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 big data, cloud
and optimized workloads.

This data center switch has been

designed with green functionality
in mind, resulting in lower power
consumption per port, which results in a
lower Total Cost of Ownership.

The 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, all of this in a very compact 1RU
unit chassis.

A smarter data center with improved

economics of IT can be achieved by
connecting servers and storage facilities
with a high-speed and low latency
network fabric that is smarter, faster,
greener, open and easy to manage.

Advanced Energy Efciency

The AT-DC2552XS provides more

than just speeds and feeds. 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 need

to balance performance with power

consumption to meet energy budgets.

High-bandwidth

As bandwidth-intensive applications

such as Web 2.0, virtualization, High­Performance 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 of I/O
adapters, reducing costs and complexity.

High Availability

The AT-DC2552XS has two slots for

hot-swappable PSU’s (Power Supply
Unit) and FANs. Also 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 the packet
to the destination as soon as the rst
packet 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 use
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.
