What drives data center costs?
• The concept of $/sqft is routinely used to describe
data center cost
• This suggests that area drives cost, which is false.

• $/Watt costs dominate TCO

Powering high density racks
• Voltage, power, and connector requirements strongly
suggest the use of 3-phase power distribution to the
rack
• A 3-phase 20A power whip can provide 7.2kW per
whip, with both 120V and 208V available at the same
time
• Two or more of these whips can support extreme
density

area savings available from compaction

Conclusion
• It is challenging to cool isolated racks >6kW or groups
>4kW in conventional data centers
• Compaction without corresponding reduction in power
consumption is ineffective and expensive
• A practical approach to density is to establish density
limits
• 7.2 and 14.4 kW are natural per-rack density limit values
due to branch circuit limits
• Where ultra high density is required, fully ducted cooling
systems provide highest performance and predictability

What if……
• The Design Concept is built on standardized
parts that can be scaled to meet the need?
• Construction Design incorporates a “Lego
Block” approach of pre-engineered
components?
• Construction is mainly done in a factory
instead of on-site?
• Commissioning tests pre-integrated
infrastructure systems.
A Quick Review: The Next Generation
Data Center Design is…
• Modular
• Plug and Play
• Scalable
• Fault tolerant
• Portable
• Pre-engineered
• Module-based mistake-proof servicing
• Has Built-in management based on TCP IP standards
• Does not require raised floor
Solutions: System Level Challenges
• Live system can be expanded at will.
• Drastically reduces one-time engineering.
• Collapses the Design-Specify-Purchase-Commission Cycle.
• Standardized, off-the-shelf, cost effective components.
• No services or integration “surprises.”
• Much of the field installation replaced by pre-assembly.
• Standardized documentation and operations.and operation

The cooling dilemma
• 15kW of blade servers can be purchased today and
installed into a single rack.
• 11kW of 1U servers can be purchased today and
installed into a single rack
• People will attempt to install this equipment
(600W/sqft) in data centers where the industry
average load is 1.4kW per rack (45W/sqft).
Don’t forget about availability
• Redundancy of cooling becomes more complex and
harder to predict at higher density
• The Air Conditioning System must be on UPS after
approximately 120W / sq ft (4kW/rack) because the IT
system will overheat during the generator startup delay
• These are difficult technical problems which make it very
difficult to reliably cross the 150W/sq ft barrier
More Problems: Dynamic Power
Variation
•
Most IT equipment draws virtually constant power independent of its
computational load
•
Early 1U servers were based on desktop technology and exhibited power
that varied with function. This was the first significant exposure of the
data center to dynamic power variation
•
P4 Xeon and near term processors do not support power management.
•
Enlightened customers and possibly public policy will dictate that
processors manage power.
•
Consequence: The data center of the future will need improved
management tools to manage dynamic power variations without overload
or malfunction.
High density answers that do
work
• Careful hot-isle-cold-isle design
– Properly laid out racks
– Properly located returns over hot isles
– Eliminating raised floor bypass leakage
• Blanking panels
– Can reduce hotspot server intake air by up to 15
degrees F (see APC white paper #44)
• Limit: 3-4 kW per rack
