Blade Server Myth #2 – Power and Cooling

In my last post about blade servers, we focused on price, and the TCO savings blades can provide. The E-Guide on Blade Server Trends also tackles the myth that blades require too much power and cooling. Here’s a snippet from that guide:

[It’s true that] early blade systems generally used more power and cooling, even with lower speed processors and less memory. Today’s blades have more efficient power supplies and improved overall thermal design. Many also have sophisticated software to help in managing heat and automating certain actions to address problems, including powering down components as needed when the temperature gets too high.

There is, however, a power and cooling issue with blades in terms of density. Even though one blade uses less than one rack server, since blade systems are designed for high density, the number of blades per footprint can be substantially higher than rack servers. (This is fact is one of their biggest advantages in space savings.) So it’s important to pay attention to power and cooling issues from an overall data center planning perspective, and to ensure that you plan appropriately.

So, the benefits of blades won’t go against your business’ green goals. When planning your data center, how do you factor power and cooling factor into the discussion?
