Three Characteristics to Look for in a White Space-Ready UPS

Data centerCloud computer vendors and colocation data center managers make every effort to maximize the scalability, efficiency, and agility of their facilities. As a result, more and more organizations are considering replacing older, transformer-based centralized power protection schemes with distributed architectures with uninterruptible power systems (UPSs) residing in the white space, or data hall.

More efficient, compact, and adaptable technologies have revolutionized both centralized and distributed UPS applications. Modularity, inherent redundancy, and ultra-high efficiency now characterize the best large UPS systems. These same attributes have migrated into smaller, even more compact systems, making distributed power protection platforms with white space UPS deployment a practical option for companies large and small.

Capitalizing on the benefits of distributed power protection schemes takes UPS hardware with an extensive and rigorous set of capabilities that fall within three categories: low total cost of ownership (TCO), high deployment flexibility, and strong manageability.


Cloud service providers, colocation data centers, and other businesses that emphasize efficient operating standards should ensure that any UPS deployed in the white space offers modular architecture - featuring multiple modular power units that share common electrical feeds, power supplies, and cabling.

Power is a major operating expense for most cloud and colocation data centers, so companies should pay close attention to energy efficiency when selecting UPSs.

Flexible Deployment

Cloud computing and colocation vendors employ a variety of hardware deployment schemes and reposition hardware frequently. When choosing a white space UPS, seek out products that support multiple configurations such as multiple thermal management options, line and match accessories, detachable maintenance bypass, and a top and bottom cable entry.

Superior Manageability

To honor demanding service level agreement commitments, cloud and colocation vendors need white space hardware that is easy to repair and maintain. For providers with distributed power architecture, that means selecting UPSs with front serviceability, seamless integration with power management software, and 24x7 remote monitoring and notification capabilities.

Distributed power architecture that places UPSs in the white space can increase the scalability, availability and flexibility of cloud computing and colocation data centers while lowering capital expenditures. To reap these benefits, however, companies must choose UPSs that reduce TCO, boost deployment flexibility and streamline management. Cloud and colocation vendors with centralized power schemes should consider switching to distributed power, while providers already using distributed power should consider implementing newer, more efficient white space UPSs.
