3 3 Integrated Cabinet Overview The Integrated Cabinets Offering: Provides high level value to Panduit s integrated data centre strategy Facilitates the progression of offering passive components to fully integrated data centres Provides solutions and consultative services that support consolidation, virtualization, and environmental stewardship initiatives in the data centre. Reduces OpEx and risks to physical infrastructure availability while enabling agility today and in the future.

4 4 Top of Mind Issues Customers face challenges to: Effectively providing thermal management to ensure proper equipment operation and uptime Enabling scalability for data centre expansions and network upgrades Manage, protect and showcase cabling and equipment Allowing open-rack accessibility with the aesthetics and security of a cabinet Ensure correct cable bend radius resulting in greater network availability

5 5 Relevant Customer Business Trends Business Trends Include: Increasing power costs Government regulated power usage Increased pressure to reduce OPEX & CAPEX Speed to market Trends Within the Data Centre Include: Rise in the energy consumption curve Collapsing layers and network aggregation switches Rise in data centre construction cost Condensed implementation timelines Virtualization/consolidation Denser environments Higher bandwidth requirements

17 17 Summary and Analysis of Thermal Management Strategies A review and analysis suggests the following conclusions: Rack-oriented architecture is the: Most flexible Fastest to implement Achieves extreme density (additional expense) Room-oriented architecture is: Less flexible Time consuming to implement Less versatile at higher density, but has cost and simplicity advantages at lower density Row-oriented architecture provides: Flexibility, speed, and density advantages of the rack-oriented approach Cost similar to the room-oriented architecture

18 Data Centre Cabinet Systems

19 19 Net-Access Switch/Server Cabinet Overview Net-Access Switch /Server Cabinet features include: In-cabinet ducting solutions to enable optimized airflow of switches Large vertical pathways for high cable count applications Cable and thermal management are scalable to address future higher density applications Dual hinge door for maximum accessibility between adjacent cabinets StructuredGround Grounding System

20 20 Thermal Management Switch Cabinet The Switch Cabinet Thermal Management System: Uses ducting to adapt side-to-side airflow switches to hot aisle /cold aisle data centre layout Tested compatible with Cisco series switches Directs exhaust air to hot aisle Matches thermal performance of network switches in cabinets with ducting equal to open frame Utilizes front and rear perforated doors designed to maximize airflow Incorporates ventilation designs optimized with input from Cisco thermal engineers

22 22 Net-Access Server Cabinet Overview Net-Access Server Cabinet features and options include: Same platform as switch cabinet to enable maximum flexibility and deployment options Vertical exhaust duct for optimal thermal performance Maximum cable management area and thermal performance Vertical patch panel configuration provides up to eight additional rack units in the same footprint

23 23 Thermal and Superior Cable Management Server Cabinet Server Cabinet Thermal Management System Key Features Include: Superior management of cables allows server fans to more efficiently exhaust air from cabinet Vertical and horizontal blanking panels direct intake air to servers and prevent cold air bypass

24 Net-SERV Server Cabinet

25 25 Net-SERV Server Cabinet Overview Net-SERV Server Cabinet features and options include: High density data and power cables are organized in segregated channels away from server exhaust for unobstructed air flow POU mounting brackets accommodate a wide range of server applications Variety of cabinet widths Multiple openings in top with fittings and sealing system Electrically bonded for single point ground Vertical patch panels maximize rack space utilization for additional servers and other devices

26 Net-Access and Net-SERV Vertical Exhaust System

27 27 Vertical Exhaust System For Maximum Energy Efficiency The Vertical Exhaust System: Removes heated air without additional moving parts through a passive system Channels heat from cabinet directly to the above ceiling return plenum increasing cooling efficiency Enables increased server densities by preventing hot and cold air mixing and eliminating hot spots Dampens noise in data centre Can be applied as modular system at initial installation or added when required as heat densities increase

28 28 Primary Application Deployed On All Heat Generating Cabinets Above Ceiling Hot Air Return Plenum Vertical Exhaust Duct Vertical Exhaust Duct Cooling Air Directed to Entire Room Cooling Air Directed to Entire Room Slab Floor * Vertical Exhaust System is also compatible with raised floor cooling systems
