Data Room Temperature and Data Room Security
Google says that when it comes to data room temperature we can raise the temperature to 80 degrees!
Most data rooms are kept between 68-72. Did you know that data center managers could save 4 percent in energy costs for every degree of upward change in the set point? This is according to Mark Monroe of Sun Microsystems.

Server Room Environment Moderated by Mother Nature
Filed under: airflow monitoring, Data Center, environmental monitoring, humidity monitoring, temperature monitoring
Recently, I saw a interesting post on Life Hacker about how to moderate PC temperature. It reminded me of a blog that I wrote a while back that talked about recycling expelled heat from the server room and using it to heat the office. The Life Hacker blog post demonstrated a method of cooling an over-clocked PC with fresh air from outside.
Although I think there are a few engineering flaws in the post, the design and concept are stable.
Using natural resources to cool your server room is clearly the next logical step in making server rooms green. Read more
SNMP Temperature Monitoring
Filed under: airflow monitoring, Data Center, environmental monitoring, SensorProbes, temperature monitoring
Whenever we buy anything for the company, I always ask if it can be connected to the network and monitored with SNMP. For example, when a new HVAC system was installed in our building, I asked if it was going to be SNMP manageable. The contractor looked at me like I was speaking Greek. Out of curiosity, I decided to search on the idea and found this company called Chipkin that makes an SNMP gateway, as does the s4group.
Why do I care about SNMP?
I care about SNMP because I want to manage everything from a central location. We use MyView in Scrutinizer. From a central location, we can monitor the network, the call center and, if we wanted to, the coffee pot.
BTW: Fugoo is considering a marketing plan for their network connected coffee maker, however, it lacks support for SNMP and the Hyper Text Coffee Pot Control Protocol.
Complete Environment Monitoring

A soup to nuts environmental monitoring solution includes more than just temperature readings, humidity monitoring and smoke detection. If electronic equipment is in the area, it is often a good idea to monitor for other environmental conditions:
- Monitoring for water leaks
- Voltage monitoring for electrical brownouts or complete electrical loss
- Motion detection and automated photo delivery
- Airflow monitoring

When it comes to monitoring the data center environmental conditions, we receive questions which pretty much cover the gamut. From staples, such as monitoring temperature or humidity, to measuring more difficult ambient conditions, such as airflow.
We also receive calls about security. This is something we can cover in a few different ways:
- Using a contact security sensor on all doors or windows.
- Motion detectors have been the topic of a few blogs.
- We can install strobe lights that can indicate security breaches.
- We can also install security cameras, which take pictures based on movement.
The importance of monitoring airflow in the office
In a previous blog, Mike mentioned the importance of monitoring the airflow in your data center, but recently we were reminded of just how important airflow is in the work environment. Normally, our office is quite chilly. However, yesterday, the employees of Ravica were treated to nice a nice toasty office to work in. It was certainly a welcome change.
The reason for our cubicles being so nice and warm was because the air conditioning (which is normally blasting non-stop) was not turning on. After several hours, the nice toasty office become a stagnant bog of stale air. Breathing nothing but other people’s CO2 was getting my coworkers and I very sluggish and lethargic – not to mention hot and sweaty.
Luckily, we had a couple of airflow sensors placed in front of the air conditioning vents. As I mentioned, the air conditioning in our work area is typically blowing all day, and quite hard, so to have it shut off for a while and let the office temperature rise a bit, is actually a good thing. However, we can now see that if it does not start back up in a reasonable time frame, things can go too far in the other direction.
To alleviate the issue of getting email alerts from the airflow sensor every time the air conditioning unit shut off, we tweaked the “Continuous time to report” field, under that sensor’s setup screen. Now we can occasionally get a reprieve from our normally frigid conditions, but if the air conditioner stays off for more than a couple of hours, the building manager and our office manager get an email alert. Of course, since we have the airflow sensor connected to a SecurityProbe, we can use escalated notifications. So if for any reason the building manager does not acknowledge the alert within an hour, then he gets a text message sent directly to his phone.
So it is certainly important to keep your expensive data room equipment from overheating, but it is just as important to keep your employees from overheating as well.

Ravica’s Sensor Controlled Relay – The Rosetta Stone?
Filed under: airflow monitoring, Data Center, environmental monitoring
A few weeks ago I talked about using the sensor controlled relay to turn on lights once an alarm had been triggered. In this blog I wanted to give another example of how versatile these units can be.
Solutions . . .
A great example is the solution that I found for a local amusement park. One of their outdoor venues was having an 
issue with their digital photography equipment overheating. It wasn’t economical to add air condition to the unit, so they needed to find a way to turn on multiple overhead fans automatically.
The management of this unit fell under the IT department, and the admin wanted to remotely monitor the data from his office (or any other portable device). The end solution was to monitor multiple environmental variables with the Ravica Sensor Probe and use the Sensor Controlled Relay to switch on the fan when the room temperature rises beyond the threshold level.
Since the sensor control unit has a user friendly web interface and an autosense feature, setting up the Sensor Controlled Relay is easy. The Sensor Controlled Relay can also be controlled via external computers, using the included SNMP command line utilities either interactively or programmatically.
From the unit itself, you can monitor the status of the Sensor Controlled Relay by four LEDs on the board. You can also monitor the unit remotely by using SNMP traps or the web interface, as well as e-mail and SMS alerts.
Implementation . . .
“The Sensor Controlled Relay provides 1 high-power SPDT 5V relay, with the maximum load up to 15A at 220 VAC. It includes Metal Oxide Varistors (MOVs) and Snubber circuits to protect the open contacts of the relays from high voltage spikes or noise transients. It monitors the power and load, and accepts a control signal, which is sent from the SensorProbe.”
We outsourced a local contractor to do the electrical work and the end result was better then we expected. Not only did we eliminate the equipment from overheating, but we are also able to trend the temp of the units over a given amount of time. This gave the admin a better picture of demand and heat generation.
Another thing to remember is the inlaid protection of this sensor. The Sensor Controlled Relay, it has a built in 16Amp circuit breaker and a 15Amp fuse (380 VAC, 125 VDC) giving it double protection for the external devices and possible damages by electrical fault. This assures protection for your sensor and your investment.
Conclusion . . .
As you can see, the Ravica Sensor Controlled Relay has many uses. It’s ability to control an array of analog devices makes it a versatile solution. It’s ability to monitor and protect itself make it a smart investment. That is why I recommend it every chance that I get.

Airflow in data centers requires careful monitoring
Monitoring the temperature of a room from a single location sometimes does not provide a good overall representation of the ambient environmental conditions. I asked around and found out about Computational Fluid Dynamics (CFD). CFD can provide 3-D analysis of how air is moving through a data center and identify potential warm areas where equipment is likely suffering from too little airflow.
I think it would be cool if our solution could provide a diagram as shown below:
I found the above image from a company called inres.com. They make a product called TileFlow. TileFlow is a powerful three-dimensional software tool for simulating cooling performance of data centers. It uses the state-of-the-art computational fluid dynamics (CFD) techniques, and is applicable to both raised-floor and non-raised-floor data centers.
If you don’t have unlimited resources, you could use our gear to create a map that looks like this:
The above is web based and the LEDs representing temperature, humidity and airflow change color based on thresholds. Notifications can be sent, and visual trends are provided, as well. It is a low cost solution, starting at $325.00 for temperature and humidity monitoring, and an airflow sensor can be added for another $125.00. That is tough to beat.
