Preparing Your Existing Data Centre for the Challenges Ahead Wui-Kiat Wong – Senior Associate
Challenges Ahead
Capital Constraints Just in Time Approach
Resilience Mul4-‐Tier
Requirements
Cloud Services
Dynamic Load Fast Deployment
Data Centre Use
Non-‐Uniform Power Densi4es
Enterprise vs Co-Location Co-‐Loca4on Data Centre Enterprise Data Centre
Physical Space
Power Density
Uniformity
Capacity U4lisa4on
Enterprise Cloud
Features Of Cloud – Load Migrates Between Physical Servers
Features Of Hybrid Cloud – Load Migrates Between Data Centres
Features Of Cloud – Load Can Change Quickly
Features Of Cloud – Quick To Scale
How Does A Typical Co-Location Data Centre Match Up To The Features Of Cloud?
Cloud Feature Co-‐Loca7on Data Centre
High Density Design to an average power density. Peak power densi4es not exhaus4vely modelled
Load Migra4on Final distribu4on typically designed around consistent load
Fast Load Growth Poten4ally long lead 4mes on equipment. Op4mised for efficiency based on steady load growth.
Server Applica4on Lifecycle – 3-‐5 years 20-‐25 year design life
What Do You Have Now ?
» Understanding of existing facility is vital. » Has a detailed site inspection been done? » Do we know the existing Facility Delivers
Existing Design Capacity? » Where documentation is not available –
contractor investigation or testing to verify configuration / performance.
» How is capacity distributed? » Is all capacity usable?

What Are The Business Needs ? Initial
upgrade to meet
immediate business
needs
Iterative planned upgrade
steps
Final planned
upgrade to deliver final
capacity
End of lease / New
DC available
Capacity Resilience Standards
Load Management
» Facilities provide more distribution capacity than upstream infrastructure capacity.
» No longer good enough to know capacity of the data centre.
» Need to know how much deliverable capacity to each rack.
» Need to know what load is dynamic and what is not.
» Need to Monitor Actual Loads (DCIM or branch circuit monitoring).

Impact Of Unmanaged Non-Uniform Loads
» Avoid the management derived SPOFs.
» Consider the cloud environment.

Use Of Modular Plant For Flexibility
» Provide capacity as required – delay capital spend.
» Higher efficiency due to higher plant loading – could delay upstream infrastructure upgrade.
» May reduce space requirements.

Capital Constraints – The Challenges
» Budgets baseline against: » Enterprise DC Compared OPEX for
Outsourced Cloud » Outsourced Cloud has economy of scale. » Drives higher efficiency
» Like for like lifecycle replacement won’t cut is anymore.
