FOCUS 2010 REVIEW


US data center industry in 2010 was the proliferation of the modular design-build


data approach beyond


center containers


and into larger-scale facilities of the bricks- and-mortar variety.


more conscious of reduction in cost - Dr Bob Sullivan


Not only have a number of smaller niche players sprouted, promoting proprietary modular design-build methodologies, but the entry into the segment by IT industry powerhouses such as HP and IBM validates the


trend as more logical passing fad.


What single advance will most positively impact the data center sector in 2011? The advance that will most positively impact the data center industry in 2011 will be the same modular design-build approach to data center development, through wider application, its promise of shorter time to market and lower cost per MW while retaining the flexibility to deliver any-tier or even multi-tier facilities.

What was the most important data center development of 2010? The realization of what the worst-case practices are in the data center and the number of people now advocating the best- case practices (such as airflow, eliminating bypass airflow, eliminating recirculation, isolating hot air from cold air).


What single advance will most positively impact the data center sector in 2011? What is coming up now is a realization that total isolation of hot and cold air is necessary to take the next step in both cooling high- density loads and doing it efficiently. The

other is the focus on efficiency in IT and in infrastructure – efficiency being factors in the identification and purchase of computing equipment and infrastructure equipment (power and cooling equipment). There is a negative though – I don’t think the vocabulary in the data center has grown from reducing cost. If it helps the environment it is fine, but I am more conscious of the reduction of cost in the data center. As someone once said, “the green kW per hour is the one not used”.

What was the most important data center development of 2010? The acceptance of modular (but not containerized) data centers has changed the economic model of data center construction and operation. The days of building a monolithic data center with fixed power, space and cooling has now faded into history. The ability to build numerous phases of space and power in a shell offers data center providers a far more capital- efficient model, not to mention greater operational efficiencies around staffing and cooling.


What single advance will most positively impact the data center sector in 2011? The rapid growth of the wholesale data center provider sector in 2010 will be the end of the enterprise-built data center. For most enterprises, SMBs and other organizations, the data center solutions provided by retail colocation and wholesale data center providers will meet their requirements with minimal capital, lower operational costs and far more reliability.

What was the most important data center development of 2010? The increased use of non-compressorized cooling solutions. End users realize you don’t need 60-degree supply air to operate efficiently. Raising the supply temperature


increases the window for free cooling options such as airside economizers and evaporative cooling. The Yahoo! Coop (which follows the design of a chicken coop for cooling purposes) was the ultimate non-compressorized design. While most enterprise and colocation data centers can’t go to that extreme, it’s possible to deploy both airside economizers and evaporative cooling in a system that delivers 73-degree air, while only running compressors 15% of the time.


What single advance will most positively impact the data center sector in 2011? Green initiatives are no longer optional and LEED for data centers is going to be harder to attain due to the fact that 2010 ASHRAE 90.1


and California’s tougher Title 24


requirements are making energy-efficient data centers part of code compliance. The baseline energy model for large data centers will be centrifugal chillers, cooling towers and waterside economizers. The bottom line is we are going to be forced to go green. Uptime at any cost was formerly the mantra but those days are gone.


Enterprises will differentiate the use of the data center by deciding what computing functions are critical to the business

What was the most important data center development of 2010? Probably the most important development, was IBM’s introduction of the z196 – it will keep banks on mainframes for years to come.


What single advance will most positively impact the data center sector in 2011? For 2011, I think cloud computing, multi-tenant


and compliance issues will


predominate. Technically, I’m hoping that Synchronous and Asynchronous replication will help break many out of the 100km limit for transaction workloads. 
