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.
