Trend of Data Center
Virtualization
– Improve Cost-Efficiency, space utilization and agility.
– Reduce IT complexity.
Higher Bandwidth Requirement for Uplink
– 10G ToR(Top of Rack) switches to surge to $1B in sales in year 2011
– 40GbE will drive earlier demand for 100GbE uplinks
Consolidation & High Reliability
– Data Center Bridging (DCB) protocols to support Lossless Ethernet Links
 802.1Qbb PFC (Priority-based Flow Control)
 802.1Qaz ETS (Enhanced Transmission Selection)
 802.1Qau QCN (Congestion Notification)
– Consolidation of Fibre Channel & Ethernet
Energy Saving
– Lower power consumption
Target Application
Data Center Top-of-Rack (ToR) Switch:
– High performance & reliability, low latency, special cooling system design and Data
Center Bridging(DCB) features are required to Data Center
– Support up to 960G switching capacity, 714Mpps forwarding rate, less than 1.93 μs
latency(DXS-3600-32S)
– Virtual/Physical stacking ensures the reliability and enlarges the bandwidth; DXS-3600
supports 480G physical stacking bandwidth.
– 1+1 hot swappable, load sharing redundant PSU; 2+1 hot swappable fan try with
smart fan design.

Hardware Overview
– Version Notes
B1 R1.10 is not backward compatible with A1
A1 R1.00 will not be maintained after B1 release
A1 CPU works fine with L2 Data Center feature.
For L3 features, we suggest to replace to B1 version.
HQ will provide free CPU daughter board to upgrade the A1 devices to B1 in
the future*

Hardware Overview
– Cooling System
Optimized cooling system to fit the heat dissipation
design of data center:
– Customers can choose desired airflow by using different power and
fan module which support
 Front-to-Back
 Back-to-Front
Hot Aisle
Cold Aisle
Cold Aisle
Hot Aisle
P.S Different airflow modules cannot be mixed.
Hardware Overview
– Cooling System
Maintain the same airflow direction in a rack to avoid unexpected system
crash and extend the lifespan
Provide the flexibility to turn the switch front panel to the same side of
server ports for better cable management
TOP of Rack (ToR)
Back-to-front
air flow
Keep the same side for DXS3600’s front panel with server
ports to
-
reduce cable length
-
simplify cable management.
