The Middle East

Introduction

What makes the Middle East different to the rest of the world?

• Booming development across the region

• Abundance of Energy

• An active awareness for the need of global environmental protection – The attempt at becoming a good corporate citizen on the Global scene.

Therefore creating the need for Energy Efficient Data Centers

Agenda

• What it means to be “Green”• Data Center Efficiency• Structured Cabling within DCs• Thermal Management and cooling• The role of Modularity within DC Designs• Environmental monitoring• Integrated Delivery / Supply services• Questions

What it Means to Be “Green”

• Materials Reduction

• Energy Efficiency

• Increased Recycling

• Packaging Reduction

• Reduction of Hazardous Material

Structured Cabling

• High density applications – • space in Data Centers are a premium• anything up from $460 to $1000 per sq ft• the more space, the more cooling

• Pre-terminated copper and fiber solutions• Lab manufactured – less wastage

• Buy-back and recycling of DC material

• Abatement – process of removal of old unused cabling. Studies have shown that airflow can be restricted up to 70% by unused cabling.

Structured Cabling

• Placement of cabling to not interfere with cooling – the need for effective cable management:

• Explore cable management options to maximize density and route cabling away from equipment cooling areas–

• Use angled patch panels and vertical patching channels - Angled panels reduce/eliminate need for horizontal cable management, saving rack/cabinet space

• RoHS compliant products

Thermal Management and Cooling

Typical Data Center Cooling Design:

Hot Aisle & Cold Aisle(Chaos Design)

• Mixture of Hot and Cold air

• Hot air recycles back into equipment – increasing heat

• More energy required to remove hot air and from cold air

Typical Data Center Cooling Design:

Effective Containment of Hot and Cold Air

(Prevention of hot and cold air mixing at any stage)

• Hot air containment via return air plenum (ceiling voids) – passive cooling

• Hot or Cold aisle containment made possible with mechanical construction (data cube)

• Cold air enters cabinet through front and / or bottom of cabinet

• Hot air escapes through top of cabinet into separate plenum (ceiling) where the air is moved back to the CRAC unit.

Containment of Hot / Cold airHot Air Return Plenum (chimney)

• No liquid / plumbing required – complete cabinet manufacturing• Effective 2kW to 30kW• Reduces operational costs by isolating hot exhaust air from cool supply air, maximizing cooling unit efficiencies• Reduces energy consumption by providing 100% HVAC utilization of cool supply air• Reduces cooling costs up to 40%• Allows for raised set points (thermostat setting) on cooling units, lowering energy consumption and costs• Permits for higher heat densities/power densities based on maximizing cooling efficiency • There are no moving parts that require redundant systems

Containment of Hot / Cold airAisle Containment

Aisle Containment

Aisle Containment of Hot / Cold airAdvantages

• Increased and Predictable Cooling capacity

• Better cooling performance

• Increased Cooling efficiency - Lower air flows required, extending the life and efficiency of the CRAC. When air-conditioning units are operated at full load, their efficiency decreases. At a speed of 50% or less, CRAC units can be operated more energy efficiently.

• Eliminates hot spots in the aisles

• Scalability with the aid of additional cooling components (eg in-row cooling units)

• Additional Security within contained environment

• A Design Philosophy – Modularity within all components – don’t over compensate

• Modularity has become the Building Blocks of a scalable, cost-effective and energy efficient Data Center

• Modular designs within:•Power supply and distribution•Cooling•Redundancy

• Fully loaded Modular Data Centers – plug and play containers – expand when require. Examples SUN, Microsoft, Google, IBM.

The role of Modularity within DC Designs

• Not just an alarm system

• Monitor and indicate on power utilisation

• Intelligent software monitors integration between power utilisation and controls CRAC units in accordance

• Can indicate placement of new equipment within under-utilised cabinets

Environmental Monitoring

Integrated Delivery / Supply Services

• Reduction of materials and wastage on site

• Recycling of materials plastics / paper etc

• Minimise freight packaging

• Quicker deployment on site – reduction of man hours and time wasted on site

• LEED credits

Integrated Supply Chain Services

• Efficient Materials and waste management
