Data center power and cooling services companyAPC is offering a number of free online tools, called APC TradeOff Tools, that give IT pros a way to view how infrastructure changes effect costs and performance in the data center.

“The tools answer questions like, ‘what will the ROI be if I increase the water chiller temperatures?’ or ‘what do I need to do to hit my energy efficiency or carbon footprint target’?,” said Neil Rasmussen, senior vice president of innovation for APC.

The West Kingston, RI-based company’s new tools include the power efficiency calculator that allows IT managers to generate “what if” scenarios regarding virtualization, power sizing, efficiency, power density, and cooling decisions.

Another new tool is the Data Center Carbon Calculator, which allows users to input data about their infrastructure and see the impact any changes would have on data center efficiency, energy costs and carbon footprint.

“If a company makes a carbon efficiency pledge, they can use this tool to drill down into different ways to achieve that goal,” Rasmussen said.

The Data Center Capital Cost Calculator details the impact of physical infrastructure design changes on capital costs; the Virtualization Energy Cost Calculator shows the impact of server virtualization and data center design choices on energy and space savings; and the Data Center Power Sizing Calculator gives details about the impact of server and storage configurations on IT load capacity and required utility input power.

There is also the Data Center AC vs. DC Calculator, which compares the efficiency of each, and the Data Center InRow Containment Selector, which recommends cooling options based on the data center infrastructure.

All of the tools can be accessed here on APC’s website.
