As AI and cloud computing reshape expertise calls for, information heart designers grapple with creating infrastructure that may adapt to unknown necessities a long time into the long run.
How do you construct a facility at this time that can stay viable and environment friendly 20 years from now? Uptime Institute specialists Madeleine Kudritzki and Chris Brown explored this problem in a latest webinar on constructing resilient information heart infrastructure.
“As a lot as we might all wish to have a crystal ball and know precisely what’s coming by way of each expertise and laws, we do not, and the adjustments are occurring a lot quicker than building can,” Kudritzki stated.
Flexibility, Not Prediction
The standard information heart planning method – forecasting particular future necessities and constructing accordingly – is proving insufficient in at this time’s quickly altering atmosphere. As an alternative, designers should embrace what Brown calls “future-proofing”: creating adaptable infrastructure that permits operators to answer evolving calls for whereas sustaining operational continuity.
The philosophy prioritizes flexibility over prediction, making certain that amenities can accommodate unknown future calls for whereas sustaining the 2 non-negotiable necessities of any information heart: uptime and reliability.
Area and Useful resource Availability
Operational calls for, equivalent to elevated energy and cooling necessities, are just about assured to accentuate. As such, information heart designers should guarantee amenities possess ample growth capability throughout a number of dimensions.
In keeping with Brown, this consists of:
-
Exterior Growth: Area for extra buildings, supplementary infrastructure parts, and future utility connections and distribution.
-
Inside Flexibility: Area for extra gear installations, enhanced cooling and energy distribution programs, and numerous gear configurations.
Bodily house represents essentially the most important and irreversible choice in information heart growth. In contrast to electrical programs and cooling infrastructure, which may usually be modified or upgraded inside current footprints, bodily expansions turn out to be unattainable with out ample room for development.
This constraint turns into notably acute in densely populated areas the place horizontal growth is restricted or unattainable, Brown famous. Many designers at the moment are pressured to think about vertical growth as their main development technique, which introduces a posh set of engineering and operational challenges.
The shortage extends past ground house to important assets. Entry to enough electrical energy and water have to be secured throughout the preliminary planning part. “If you are going to improve your capability, you are going to must have these assets accessible for doing that,” Brown stated.
With out these assets, even essentially the most versatile designs turn out to be unworkable.
Capability Growth Methods: Phased vs. Modular Approaches
Brown outlined two main methods for constructing expandable information facilities, every with distinct benefits and vital trade-offs.
The Phased Strategy: Gradual Capability Addition
The phased method includes putting in full distribution programs throughout the preliminary building, then progressively including capability parts, equivalent to chillers, pumps, mills, and UPS programs, as demand grows. The tactic provides cost-efficiency by spreading capital expenditure over time and avoiding over-provisioning.
Nevertheless, this method carries a hidden hazard: commissioning limitations. When including capability to programs already supporting important masses, operators can not totally take a look at new installations with out risking disruption to current providers.
Brown illustrated this problem with a cooling system state of affairs: An operator may add a chiller that will increase their capability from 1,000 kW to 1,500 kW. The whole lot works tremendous till operations method 1,300 kW, at which level issues emerge that correct commissioning would have caught. At that important second, the operator should diagnose and repair points whereas sustaining help for current important masses – a precarious scenario that may result in catastrophic failures.
The Modular Strategy: Discrete Capability Blocks
The modular method takes a basically completely different path, utilizing full, self-contained capability blocks moderately than particular person parts.
Every module capabilities as a discrete unit, consists of all needed infrastructure, and might be totally commissioned individually from current programs. This separation permits thorough efficiency validation, troubleshooting, and optimization earlier than integration, considerably decreasing the chance of surprising failure.
Nevertheless, the method requires excessive upfront capital funding that have to be rigorously weighed towards operational advantages. Set up prices end result from duplicated distribution programs throughout modules, redundant management programs for every capability block, and extra infrastructure required for module independence.
Making the Strategic Selection
The selection between approaches relies upon closely on particular circumstances, together with load traits and organizational threat tolerance.
There isn’t any single right reply, Brown stated. “These are the issues that one has to consider when making an attempt to design a facility at this time for the unknown masses that now we have sooner or later.”
