Better Modeling, Better Results

By John Peterson | Sep 05, 2017

Modeling your data center using Computational Fluid Dynamics (CFD) can help get a better picture of the data center performance, hot spots, air flows, pressures and more.  There are natural concerns about the cost, complexity, and how a CFD can compliment your floor design and work with your Data Center Information Management (DCIM) tools. CFD […]

Lights Out

By John Peterson | Aug 05, 2017

Lighting in the data center has been a target in data centers for a while, as they can have upwards of 1.5 watts per square foot of white space.  While this power density may seem small by comparison with the computing loads, any lighting with over 1.0 watts per square foot is likely higher than […]

Adding Cooling

By John Peterson | Jul 07, 2017

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

By John Peterson | Jun 06, 2017

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

By John Peterson | Apr 06, 2017

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 […]

Data Center Infrastructure Management (DCIM) Tools

By John Peterson | Mar 06, 2017

DCIM: What used to be a much simpler subject a few years ago has blossomed into a fast-developing part of the data center industry.  Today it seems like there are many qualified tools and packages on the market to help with managing your white space, but also much beyond.  This has mainly come from the […]

CRAC vs. CRAH

By John Peterson | Feb 06, 2017

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?

By John Peterson | Jan 06, 2017

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

By John Peterson | Dec 06, 2016

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, […]
