IT Market Review
•
The demand for IT support continues to grow.
– Forecasts for 2012 from DatacenterDynamics (DCD)
• 7% growth in the number of data centers
• 15% growth in racks
• 19% growth in energy usage
• IT investment to increase by 17%
– DCD justification for growth
“[The] World is becoming more IT dependent. Even in ‘developed’
economies [there is] still considerable room for expansion of IT
functions within businesses, Government and society.”

Data Centers Today
•
Critical gear is more densely packed
– More cabinets in the DC
– More equipment in each cabinet
– Within the equipment itself, the internal
components are more tightly packed
– New equipment has better performance,
but often has “greater demands,” meaning
the need for more power and more cooling
• In the past, 3 to 5kW racks used to be
common
• Today, racks can demand up to 35 kW of
power

Risk in the Data Center
•
2010 survey of 453 DC management professionals about outages
in the prior 24 months
– 95% of the data centers experienced an unplanned outage
– 2.48 was the average number of outages during that 24-month period
– 107 minutes was the average outage duration
– Row- and rack-based outages were more common than complete outages,
– The causes of data center outages
29% UPS system failure
24% human error
12% weather-related
15% water, CRAC/H failure
10% generator failure
5% IT equipment failure
5% other
– Conclusion
“… need to implement power, cooling and monitoring systems ….”

DC Downtime: It’s Not Free
Expenses include:
cost per minute
• Detection
• Containment
• Recovery
• Equipment
• Productivity Loss
• Lost Revenues
• Business Disruption
A single downtime incident could easily
$5617cost per minute (average)
x 107minutes duration (average)
cost hundreds of thousands of dollars
$601,019 cost of an average outage
Based upon a survey of 41 data centers

Get the Data You Need
Begin at the PDU
• Racks already require
power distribution units
(PDUs), so choose PDUs
with intelligence and
features to protect your
data center
• Consider remote outlet control
features (switching PDUs)
– Power up or power down
equipment through the web
– Disable unused outlets
– Control the power-up sequence
• Ideally suited for isolated or
distant locations
– Power monitoring
– Environmental monitoring
– Security monitoring
– No need to roll a truck to fix a
stuck server at an unmanned or
remote site… just cycle the
server’s outlet to reboot
– Remote access and
alerting capability
– Expandable

Rack PDU Monitoring instead of
Branch Management Monitoring
Rack PDU Monitoring

Branch Management
Monitoring
preferred
A finer level of detail
• Monitoring within the rack
A coarser level of detail
• Power monitoring
• Monitoring before the rack
–
by PDU
–
by circuit
–
by outlet
• Power monitoring
–
• Rack PDU breakers not detected
• Rack PDU breakers are monitored
• Option of monitoring the rack
environment
–
by circuit only
• Most appropriate with a single
circuit of 20A or less, with no
further branching downline
temperature, humidity, airflow, etc.
• Appropriate at all times

Take Control: Airflow at the Rack
Cooling Improvements
•
•
Is a passive exhaust return system enough?
–
Is the hot air freely moving away from the servers?
–
Are server fans being overworked?
Manage the rack’s cooling with an intelligent, pressurecontrolled return air system
–
Fans in the chimney draw hot air from the rack
–
The airflow rate is tied to the rack’s cooling needs
–
Fans within the server only need to push hot air out of the
server chassis
•
A steady airflow through the rack minimizes the chance
of hot spots
•
Network switches – a special problem
–
•
Draws air from the side or rear and exhaust to the front
A special solution
–
Change the airflow to align with the rack cooling solution

Take Control of the Entire DC Network
DCiM
•
Implement a Data Center Infrastructure
Management (DCiM) solution
– Centrally or remotely manage the entire data center
infrastructure
• Facility power, chillers, water, security, fire suppression,
lighting, air conditioning, etc.
• Data center equipment and operations
• Manage multiple locations
– Get the full picture
• See the overall health and operation of your DC
• Know the operational and maintenance status of every
significant piece of DC hardware
• Use the DCiM solution as your touchstone to all alerts
and issues that can affect the operation of your data
center.

Even a basic hardware enhancement
can be significant
•
Locking Receptacles
– Simplify server deployment time by securely
locking power cables instantly
– Protect against vibration and external elements
that can dislodge external locking clips or guides
– Compatible with standard IEC C14 or C20 plugs
•
IEC C13 & C19 Plug Shields
– Secures extra outlets from unauthorized use
– Installs in seconds, and easily removed when
the special key is used

RCDs in the Data Centre
•
Are RCDs needed in the Data Centre?
– Get-out clause
– Nuisance tripping
•
Newer RCDs with Class A Type SI
– No longer a technical foundation for avoiding
– Opens the door for liabilities
•
How do we go about fitting a Data Centre
– Green field – easy
– Brown field – expensive
•
Solutions
– PDUs with RCDs
– Ability to test
– Monitoring Residual Current over time

Conclusion
•
Use the best tools to minimize risk
– Monitor to find problems before they become serious
– Improve your operations through consolidation and
equipment management
– Optimize your cooling solution for most effectiveness and
least expense
– Use remote capabilities to respond at any time from
anywhere
•
The best tools
– Intelligent PDUs
– Intelligent airflow management
– DCiM
