Got any Smart Ideas?

I just received the check from our major project at the CH2 data center in downtown Chicago. A $544,000 rebate for validating our energy savings is a pretty impressive feat. The projects included VFDs on DX Cracs, modifying the BMS and economizer, installing hot aisle containment, installing lighting occupancy sensors, and upgrading the cooling towers with new fans and new evaporative media. They tell me this is the biggest check they have ever issued and we are doing a big presentation ceremony in a few days to celebrate this projects successes. Big congratulations to the team I worked with that made this all a reality, Dan Fargano, Travis Nelson, and Jason Brick.

 

The Raised Floor Perspective-Utilizing Raised Floor Space

Space, Power density and redundancy are three highly important facets of any successful data center. Today I will turn my focus toward space. Data center raised floor space can be very hard to come by. Whether you are designing the most efficient layout for an enterprise center, allocating cage space for a colocation center or arranging an environment with in a cage, space is important. Most often more space cannot be added and when it can the cost will generally be substantial. Therefore it is paramount to effectively use all the space available at a given center. This is not always easy. Equipment on the floor such as PDUs, RPPs, CRACs and CRAHs can get in the way. Access clearances need to be provided and take up additional space beyond the footprint of the equipment itself. Structural pillars can present an obstacle to the overall space layout. Also cages that separate environments at colocation sites need to be taken into account. For various reasons data center floor layouts can change over time. Replacing old equipment with newer equipment that has a smaller foot print or customer turnover are just a few examples. Changes on the raised floor can leave equipment in the way of utilizing raised floor space most efficiently over time. Most people would not think to move critical IT infrastructure, however doing so can lead to more usable and revenue generating space.

PUE 1.0: Mission Impossible. But how low can you go?

Everyone knows how hard it is to continue to improve PUE. I’ve even included a graphic representation of how spending can influence your PUE:spendvspueSo we all know our struggles, and as the industry matures it becomes easier to increase efficiency under a given budget constraint. But the general idea, that every dollar spent has less impact than the dollar before it (save for some hurtle points) in general will hold true.
