THE EVOLUTION OF TECHNOLOGY SPACES

Dave McGrath Director Business Development Construction, Facilities and Engineering Division

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

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 redundancy

Blade Servers

High-density is going to bite your customer

It’s not if, it’s when!

“Catch 22” for IT managers None of the above Poor location Excessive facility cost Insufficient raised floor Insufficient power Excessive heat 0% 5% 10% 15% 20% 25% 30% 35%

 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

Power Cooling Service Engineering Space Improvements Racks

Thinking about Data Centers “by the square foot”

is obsolete

Traditional Configuration

Room-oriented cooling airflow patterns

In Row Configuration (Coupled Cooling)

Row-oriented cooling airflow patterns Predictable Performance

Alternative cooling architectures Method Traditional room oriented raised floor cooling In-row In-row with hot aisle containment Application Low density Very flexible Medium density General use Very high density Targeted zones Assured redundancy Rack-coupled Density 1-5kW per rack 3-15kW per rack 10-25kW per rack Very high density specific racks Mix of very high and low density 20-45kW per rack

Why is it so critical to address during design?

In-row rack-coupled architecture

  

“Coupled” to adjacent IT racks



Up to 40kW rating today with efficient designs



Higher availability via N+1 standards Predictable performance Mix into existing legacy data center

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

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 Configuration:

 

Select rack IT actual loads reflected in design



Simulate 3 rd equipment party

 

Model power Model airflow

Scale & Manage Power at the Rack

1.4 kW - 12.5 kW, 15A - 50A, Horizontal or Vertical Mount



Control individual outlets



Turn unused outlets off



Recycle power to locked-up equipment



Monitor current

 

Avoid overloads Balance loads across phases



Sequence power-on



Avoid in-rush current

Switched Rack PDU



Power high density racks



Multi-branch units supports 12.5kW



Fit up to 4 units in one rack



42 outlets on one strip

Manage at the Row / Room

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


