To HAC or CAC? That is the Question
Blog Category: Data Centers

Posted by: Mike Peterson on February 19, 2015

In today’s high-density virtualized data centers, keeping equipment cool is one of the topmost concerns among data center managers. And the problem is two-fold—not only does cooling represent about 30% of operational costs, but not having uninterrupted proper intake temperatures for equipment can result in overheating and failures that lead to even higher operating costs.

Consequently, many data centers oversupply cold air, placing undue financial strain on data center operations as CRAC units require more power to provide more cool air. And despite the oversupply of cold air, many data centers still experience hot spots.

Fire Suppression for Aisle Containment
Blog Category: Data Centers

Posted by: Mike Peterson on March 05, 2015

In my last blog, we talked about hot-aisle and cold-aisle containment as an ideal solution for keeping equipment cool and saving energy in today’s high-density virtualized data centers.

Depending on the location of the data center and location of the containment system within the data center, some form of fire detection and/or fire suppression is required inside the enclosed aisle.

Let’s take a closer look at fire detection and suppression in the data center and how aisle containment systems can impact the requirements.

Better Data Center Performance Comes Down to Thermal Management
Blog Category: Data Centers

Posted by: Mike Peterson on May 21, 2015

To achieve impressive thermal management efficiency levels, data center administrators can select from a range of options – from simple first steps to more complex measures. How do you know where to start, and what will provide the most efficient, reliable, and cost-effective thermal management strategy?

Let’s first define “thermal management.” You may hear the word “cooling” in thermal management conversations, but it doesn’t mean just supplying cold air (although that is one element of thermal management) it also includes rejecting the heat that is being created by the IT load – in fact, air-conditioning in a data center typically accounts for 35% of total operations costs. The goal is to ensure that hot and cold air don’t mix, and to reject hot air inside the data center by taking the hot exhaust from equipment and moving it outside the space.

10 Terms to Know About High Speed Assemblies
Blog Category: Data Centers

Posted by: Mike Peterson on June 04, 2015

As the need for speed in the data center continues to grow, you’ve probably been bombarded with high speed assembly terms like SFP+, QSFP+, interoperability, DAC, AOC, EEPROM … and the list goes on! High speed assemblies are ideal for a number of different data center deployments, such as top of rack (ToR) and middle of row (MoR).

With new products and technologies being introduced at what feels like a daily rate, we thought a quick guide to various high speed assembly terms and acronyms would be useful. Here are some of the most commonly used phrases used when discussing high speed assemblies.

Environmental Monitoring: Crucial to Data Center Success
Blog Category: Data Centers

Posted by: Mike Peterson on July 30, 2015

Data centers make up a unique eco-system of their very own. Keeping equipment cool is a necessity – but too much cooling can lead to excessive energy costs. Properly separating hot exhaust air and cold supply air is also a must to prevent hot air from cycling back to the IT equipment intake, and cool air from returning to the cooling unit. The best way to determine the effectiveness of your CRAC is to constantly monitor three crucial areas. Here they are...

Achieving Five Nines of Availability
Blog Category: Data Centers

Posted by: Mike Peterson on November 12, 2015

When talking about availability, the term “five nines” refers to 99.999% (count the nines – it’s where “five nines” comes from). That percentage is often referred to as “reliability” in the data center world, but five nines actually refers to the percentage of time that a device or network is available for use. So how do you get more “nines” into your data center uptime?
