Don't Let Cooling Costs Burn Your Dollars

Posted by RJ Tee on May 17, 2017 1:05:36 PM


Server Technology product manager Robert Faulkner knows a thing or two about data center power. With nine years at the company under his belt, Faulkner is keenly aware of the problems presented when you’re trying to walk that fine line between properly cooling your data center floor and keeping your costs low.

The problem, as he explains it, is like this:

“As temperatures rise, the life of your equipment drops. Most of your money is in servers, network gear and storage, so you want to make sure these elements have proper cooling,” Faulkner says.  (You can learn about top tools used for environmental montoring here)

Faulkner explains that with power strips residing in the back of the rack, the heat produced by servers is not always accounted for. One solution, he says, is proper cable routing.

“If you have a lot of cordage in the back, that’s a horrible situation,” he says. “The fan can’t cool the server. It’s just spinning, it’s really hot and it’s damaging your equipment.”

As a result, many data center managers assume their cooling is working efficiently, when it’s really burning up dollars by the minute.

The answer, Faulkner says, is to adopt smart rack PDU technology, such as the Alt-Phase HDOT PDU from Server Technology.

The benefits are many:

  • HDOT PDUs allow for shorter, more simplified cable runs
  • Increased airflow through the equipment
  • Intelligent rack PDUs report on current draws
  • Complete compatibility with Sentry Power Manager

Server Technology’s High Density Outlet Technology PDUs simultaneously monitor both power consumption and temperature within cabinets. Built-in alerts and reporting functions transmit data to HVAC systems, DCIM tools and key personnel. And in keeping with current trends, HDOT PDUs are built to operate at full power load in a 65 ̊C (149 ̊ F) environment, allowing you to run your data center at a warmer ambient temperature.

When combined with SPM, Server Technology’s smart rack PDUs become exponentially more powerful. SPM allows you to see in real-time what’s going on with your data center equipment. With optional temperature and humidity probes, you can maintain the proper cooling and heating mix on your floor 24/7. Customizable reports let you regularly see temperature data, allowing you even predict when equipment may be about to fail.

Downtime Is a Big Problem, According to Fed IT Workers

A total of 300 federal IT workers recently took the time to grade their departments’ downtime management strategies in a survey conducted by Meritalk, as was reported in a Financial Times article.

The results of the survey were not pretty, indicating that downtime is one of the biggest cyber issues facing the federal government in 2015.

Some 36 percent of federal IT professionals gave their IT departments a grade of “C,” meaning average to below average, for downtime management performance. Additionally, just 29 percent of federal IT professionals believe that their IT department is fully aware of the impact that downtime can have on their agency’s overall performance.

Furthermore, about half of those surveyed indicated that their data center lacks the necessary computational power, data storage and personnel needed to ensure optimal efficiency.

This study is alarming given the fact that the transmission of real-time information is critical for facilitating a wide range of important federal tasks. These tasks range from safety inspections to healthcare. Without the help of a reliable network and a fully optimized data center, many workers are finding it difficult to complete important tasks.

What can be done to rectify the federal government’s data center woes? Real-time data center power monitoring, as well as environmental monitoring, is an essential technology that would help ensure the safety and stability of core government networks, in regard to power. Federal IT professionals require real-time access to energy consumption metrics provided by this technology in order to prevent system overloading, network crashes and capacity shortages. With such a technology, the federal government could gain critical oversight into real-time power consumption as well as environmental data.

Recently, a lot of customers have been asking us here at Server Technology about maximizing uptime.

Customers want to know: With the multitude of power-related challenges facing data centers today, like unplanned outages; increasing security threats; new, relatively untested technologies such as SDN; and the ongoing threat of natural disasters, is striving for constant uptime a realistic goal or a pipe dream? Many feel that they are fighting a losing battle against this slew of challenges.

Our response is that it’s easy to get frustrated with the increasing number of demands facing your data center. But it’s also easy to manage power effectively when you have access to a reliable data center power management solution that can provide the following features:

  • Real-time environmental alerts: Stay on top of environmental challenges like heat spikes and condensation with advanced temperature and humidity monitoring.
  • Capacity planning: See exactly how new infrastructure and technologies fit in with your existing equipment. Capacity planning tools will let you see how much power your equipment is using, and how much room you have left before reaching your ceiling.
  • Power draw data: When downtime occurs, you need to be aware of it. Don’t let servers and switches fail for extended periods of time without being noticed. Gain advanced power draw information so that you can keep a close watch on your facility at all times.
  • Remote management: Make critical power adjustments from any location with remote management. You don’t have to be physically present in your data center to oversee your equipment and make key changes.

So, don’t get overwhelmed trying to maintain uptime. Get the right technology to ensure it. Server Technology, a leading provider of data center power management software, can help you ensure uptime in an unpredictable environment. Click here to request a demo today.

Putting Your Excess Data Center Heat to Use

Posted by Eric Giacomini on Jan 26, 2015 9:48:50 AM



Your servers generate a ton of heat over the course of a single day. So, why not take this excess heat and pump it back into your office building during cold winter months? It’s a great way to save money and reduce waste at the same time. 

Think about it: A typical server running at 400 watts will generate almost 1,400 British thermal unit (Btu) per hour. A standard 20-by-20 room with a 10-foot ceiling only needs about 35,000 Btu per hour to maintain a 72 degree temperature. Since a large enterprise will run several thousand servers at a given time, it will generate more than enough energy to keep an entire building heated for an extended duration.

In fact, as Amazon is proving, it could be enough energy to heat a whole skyscraper.

Amazon is in the process of constructing a system that will take waste heat from one of its data centers and transfer it to the company’s nearby high-rise office building. The project is expected to save Amazon about three-quarters of the electricity that it would have otherwise had to purchase to heat the facility. Additionally, by removing the heat from its main data center, Amazon will reduce the amount of water and air needed to keep its infrastructure cool.

If you’re thinking of implementing this strategy in your facility, don’t move forward without a reliable environmental monitoring solution that will give you real-time information about the temperature in your data center. After all, when transferring large amounts of heat, it’s critical that you maintain a close watch on your equipment to ensure safe temperature levels.
