It’s crucial to understand other business drivers in making decision in terms of modular data centers. This report analyses the capital costs of two data centers whose capacity, cooling architecture, power architecture, level of redundancy, density, and the number of racks are the same. Learn more about the key considerations to deploy the right modular ...

There is an increasing trend towards N+1 UPS architectures – rather than 2N – as IT fault tolerance through software continues to improve. There are two common ways N+1 can be achieved: paralleling multiple unitary UPSs together or deploying a single UPS frame with multiple internal modules configured for N+1 redundancy. In this paper, we ...

Data center operations and maintenance teams should always be prepared to act swiftly and surely without warning. Unforeseen problems, failures, and dangers can lead to injury or downtime. Good preparation and process, however, can quickly and safely mitigate the impact of emergencies, and help prevent them from happening again. This paper describes a framework for ...

Today’s data center power and cooling infrastructure has roughly 3 times more data points / notifications than it did 10 years ago. Traditional data center remote monitoring services have been available for over 10 years but were not designed to support this amount of data monitoring and the associated alarms, let alone extract value from ...

Lithium-ion battery prices have decreased over the years and are now becoming a viable option for data center UPS. This paper provides a brief overview of li-ion batteries in comparison to VRLA batteries for static UPS applications, including optimal chemistries and technologies. A 10-year total cost of ownership (TCO) analysis is provided showing li-ion is ...

There is much confusion in the marketplace about the different types of UPS systems and their characteristics. Each of these UPS types is defined and the practical applications of each are discussed with advantages and disadvantages listed. With this information, an educated decision can be made as to the appropriate UPS topology for a given ...

IT virtualization, the engine behind cloud computing, can have significant consequences on the data center physical infrastructure (DCPI). Higher power densities that often result can challenge the cooling capabilities of an existing system. Reduced overall energy consumption that typically results from physical server consolidation may actually worsen the data center’s power usage effectiveness (PUE). Dynamic ...

Data centers today lack a formal system for classifying infrastructure management tools. As a result, confusion exists regarding which management systems are necessary and which are optional for secure and efficient data center operation. This paper divides the realm of data center management tools into four distinct subsets and compares the primary and secondary functions ...
