Adding Cooling
There are a number of ways to effectively and efficiently cool a data center. Below are some considerations when looking to add cooling to your critical space. Strategy: Understand the cooling methodology for your data center: air and/or water; raised floor; hot/cold aisle; containment; perimeter cooling; localized cooling; liquid cooling; etc. Establishing a new cooling […]

3+ Billion Users, 30+ Billion Connected Devices
Sometime in the next year the world will have about 3 billion users of the internet. This expansion will continue to increase to about 3.5 billion or more by 2018 as access to new markets continues. India and southeast Asia will see double-digit growth, assisted by Google, Facebook and others as they create new ways […]

Tin Whiskers
Tin whiskers form when tin plating on component leads is under pressure. The tin squeezes out to form filaments as thin as a human hair. The whiskers grow long enough to potentially cause a short circuit. This concern has come about since the European Union adopted restricition of hazardous substances, which has led manufacturers to […]

CRAC vs. CRAH
I had this come up recently… what is a CRAC (pronounced ‘crack’)? What is different from it than a CRAH (pronounced ‘craw’ or ‘cray’)? CRAC = Computer Room Air Conditioner A CRAC is often thought of as having an internal compressor, thus not needing the support of a centralized chilled water system. But this also […]

What do we want from CFD?
Computational Fluid Dynamics (CFD) analysis of data centers has been going on for some time, but how does it help us? For an existing data center, do you want a CFD model to show you things you already know, such as hot or cold spots? 90% of the time we are using a CFD report […]

Cooling Tower Water Storage
When operating your data center, often there are backup measures to keep things running during a power outage. Generators may be the first thing that comes to mind, as they bring power back during an outage, but along with that the cooling systems also need operate. As the heat is rejected through the mechanical systems, […]

Energy Management Systems
Have you heard the phrase ‘you can’t manage what you can’t measure?’ This is true for your data center, and having an energy management system in place with your hands on the reigns gives you a good means to measure and manage. An energy management system (EMS) is to let you see where your energy […]

Warmer Chilled Water on Existing Systems
So we are looking to save energy, and one of those ways is increasing the chilled water temperature. But how does that save anything? Increasing the chilled water temperature brings it closer to the condenser water temperature and thereby reduces the amount of work (lift) a chiller has to perform. Since the chiller usually has […]
