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 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, 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 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 shor test 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.

AT- DC2552 XS | High Performance, Low Latency Top-of-Rack Data Center Switch
Resilient Ethernet Fabric
Resilient Ethernet Fabric (REF)1 increases availability using a dedicated bypass link. If one of the links or units fails, the bypass link restores connectivity. By setting up the same L ACP trunk group over two AT-DC2552XS units, REF uses link aggregation to increase throughput beyond what a single connection could sustain, while providing link path redundancy.
» Master-less
» Layer 2 mesh on spine-leaf model
» Active-active, multi-path
» Easy setup
Master-less
» There is no “synchronize” process which the hardware
stacking feature usually requires. Instead of setting up “masters” and “members,” REF recognizes the other device just as a partner and eliminates the downtime of master fail-over.
Layer 2 M esh on Spine-Leaf
» One pair of AT-DC2552XS switches with aggregation
mode suppor ts up to five pair of AT-DC2552XS with ToR mode, which would connect a maximum of 40 servers per rack.
Active-Active, Multi-Path
» While Spanning Tree Protocol requires active-standby
configuration and switchover time for failure, REF supports active-active configuration, preventing any perceptible disruption in the case of a link failure. Even if one of the devices fails, an alternative path is secured and ensures absolute minimal network downtime.
Easy Setup
» REF is configured with QSFP modules between two
AT-DC2552XS units, and breakout cables between the ToR and the aggregation switch.
