"The fatal conceit with managers is that tomorrow will look like today..."Peter Druker


Are we designing towards, or away from future problems?

High Density – today’s problem

High Density Requirements Increasing power Increasing need for cooling Increasing runtime Increase need for

redundancyBlade Servers


High-density is going to bite your customer

It’s not if, it’s when!


“Catch 22” for IT managers

Excessive heat

Insufficient power

Insufficient raised floor

Excessive facility cost

Poor location

None of the above

What is the greatest facility problem with your primary data center? (Source: Gartner, 2006)


IT Facilities


How will it be solved

With a Clear and Concise language on Scalable, Modular datacenter design.

Rack, Power, and Cooling Infrastructure will be designed using pre-engineered modular components and configuration tools


Traditional Design

Unable to Respond adequately to today’s growing power and

heat loads


We must re-tool the design process

IDC: Time to push ‘reboot’ button…

“…it appears that it will be cheaper to build new

datacenters to accommodate blades than to attempt to retrofit

the existing ones…”


It is getting to the CEO’s plate…

“Power will be #1 design issue for many IT shops over next two to three years…”

“RFG predicts that power and cooling costs will increase to more than one-third of the total IT budget. This will elevate this cost element into a priority position for CFOs, facilities managers, and IT executives.”

“Coordination with facilities management is crucial to successful power and cooling planning”

-Robert Frances Group, January 06


We must all pay close attention…


Density is driving an unprecedented collision between IT, Facilities and vendors

We have a shared problem

The traditional solutions won’t work, and the typical solution providers are either focused on making the problem worse or hoping it goes away

The shared problem is getting bigger and hairier by the minute

We need a shared language to promote learning

Learning offers an opportunity for standardization, leading to lower costs, higher availability, and much greater productivity

Everyone has to decide if they are part of the problem or part of the solution


Network-Critical Physical Infrastructure (NCPI)

Essential foundation of

reliability


Rack Power

Implement designs with a completely scalable and modular approach at the rack level Rack Power delivery must be scalable in response to

density variation Rack Power must be redundant (UPS N+1 or greater) Rack Power design must be completely flexible in

configuration and voltage

The Rack is the Basic Building Block of any IT deployment.


Design the rack accordingly

Rack Cooling

Eliminate the unpredictable nature of traditional cooling architectures in dense environments

Closely couple the IT load with cooling capacity Increase Capacity per rack Increase Cooling Efficiency

Model the cooling requirements from day 1 and be prepared to adapt to change

Power In equals Heat Out design in accordance with the dynamic nature of the load

Summary

“Man must sit in chair for very long time before roast duck fly in mouth…” Chinese Proverb

Take Action …understand the Rack Level challenges and design accordingly!
