Increasing Your Power System Efficiency


The power system is considered the most critical element of the data center. Effectively it is a chain of key electrical sub-systems and components that are the essential elements for delivering uninterrupted, conditioned power to the IT equipment. This article is an part of the DCK Executive Guide to Energy Efficiency and the fourth article in a 5-part executive series on Energy Efficiency. Read More

Energy Efficiency: Measuring A Facility’s Power Use

While there continues to be a bit of difficulty in trying to quantify the energy efficiency of a data center’s IT systems, the efficiency measurement of the data center facility infrastructure is now is a well-defined metric. This article, which examines energy efficiency in the facility, is third article in a series on energy efficiency. Read More

IT System Efficiency in the Data Center

In the past, IT equipment manufacturers and their data center operators were focused more on maximum performance, not energy efficiency. While the newest generations of computing hardware have continued to increase in performance, they have also become highly focused on energy efficiency. This article is the second installment in a five-part series on energy efficiency. Read More

Key Factors Impacting Total Cost of Ownership

There are many factors that go into a data center’s total cost of ownership (TCO) besides site selection. As part of the Data Center Knowledge Executive Guide Series on Total Cost of Ownership we will look at other factors that impacts a data center build or buy TCO analysis.

Impact of a Data Center’s Energy Cost on TCO

Like fuel cost to an airline, the cost of energy represents one of the most significant Total Cost of Ownership (TCO) components in the data center. Over the long term it is one of the most variable costs, and based on current and foreseeable trends, it will continue to rise over time. Read More

Total Cost of Ownership: An Executive Overview

Total Cost of Ownership “TCO” is basic and easy to calculate; just ask any first year economics or business major. Nonetheless, the true TCO of the data center is somewhat more elusive to project accurately. There are many subtleties which can be overlooked or are simply unaccounted for (or perhaps underestimated), over the operational life of a data center. Read More

Data Center Build or Buy: Factors to Consider

Decisions made in the design and build stages will not only affect the total CapEx of the data center, but forever impact its energy efficiency and long term operating costs, as well as limiting the functional life of the data center. Here are a few questions to ask when deciding to build or buy your next data center. Read More
