DATA CENTER

Computer Room

Planning

Jeffrey Lam RCDD

What is a data center?

Data Centers

– “nerve centers” of the

organisation

– centralize & consolidate IT

resources

– support critical business

operations.

– provide uninterrupted service to

mission critical applications

• 7 x 24 x 365 availability

• Power & network redundancy

• Physical & network security

• Environmental monitoring

• Air-conditioning / thermal mgt

• Fire suppression systems

Different Tiers of data centers

Data center space is precious, use it wisely.

Hot & Cold aisles

•Cold air directed to

cold aisles through

raised floors.

•Hot air return through

ceiling space

•Computer Room Air

handling units (CRAU)

located along hot aisle.

•Under the raised floor,

cables are routed along

hot aisles to prevent

obstruction to

incoming cold air.
