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

Avoid Damage Caused by Data Center Humidity
Filed under: Data Center, environmental monitoring, humidity monitoring
Agricultural experts in my hometown regularly uttered the phrase, “It’s not the heat, it’s the humidity.” In the data center environment, humidity can be an overlooked hazard. Both heat and humidity are threats that require attention in data centers.
Understanding how humidity in data centers affects electronics is an obvious requirement for Data Center Managers because it has a direct effect on a company’s bottom line. Ensuring that your business has ideal data center humidity levels impacts the lifespan of equipment and can decrease utility costs. Read more
Kansas Department of Health & Environment’s IT Infrastructure Failure is Recovering
Filed under: Data Center, environmental monitoring, Notifications, SensorProbes
A recent news article reported on an IT infrastructure failure at Kansas Department of Health and Environment (KDHE). The issue was compounded by the fact that it occurred as students were preparing to enter school and needed birth certificates, immunization
records, and other state documents. Because they were no longer electronically accessible, approximately 120,000 of these records had to be retrieved from storage in a central Kansas salt mine, no doubt adding significant man-hours to workers across Kansas.
According to the Healthcare IT News article, the technical problems stemmed from a storage area network (SAN) failure, the hardware which stored agency records. Read more
Is an environmentally sustainable data center possible?
One of the biggest concerns for IT facility managers is monitoring the temperature in data centers and server rooms to make sure that the excessive heat produced by hardware is not accumulating to dangerous levels that can overheat the servers. This is an important task for the obvious reason that overheated equipment can lead to expensive hardware damage and loss of data. However, conventional HVAC systems that use chilled forced air to cool data centers are highly inefficient with regards to energy consumption and therefore indirectly effect CO2 emissions. Being a bit of a green building geek, I looked up some examples of data centers that are using new (and old) technology for lower impact cooling. Read more

Physical Security for Data Centers
Data centers house some of the most valuable and irreplaceable assets for any organization. For this reason, physical security is of the utmost importance when designing a data center. Depending on the size and budget of the organization, physical security measures can include everything from solid floor-to-deck concrete partitions to biometrics screening.
There should also be a number of sensors in place that can detect when anyone, authorized or unauthorized, accesses the data center. The following 5 tips show how Ravica can offer effective solutions for that final line of defense. Read more

Data center in hot water
Filed under: environmental monitoring, temperature monitoring, water leak monitoring
So here I was, thinking about what today’s blog would be, and my buddy Mitch gave me today’s title. Although a corny title, it describes an issue that happened with a customer of mine. The good news is that Ravica’s probes helped save the day.
Joe, the Admin for an ISP, had purchased multiple water sensors and temperature sensors for his six data rooms. Around 3:20am on a Sunday he got an alert from his SensorProbe. Apparently, the temp in one of the server rooms was rising. Since he was on call, he decided to get into his truck and see what was going on. On his way to the building, he received another page. The water sensor had triggered. He was now very concerned.
Once he reached the data center, it was obvious to him what had happened. One of the valves of the heating system started to reached its limit. This quickly caused the temp of the pipes to rise, which is what triggered the temperature sensor.
The relief vales reached their breaking point and started to spray water all over the first data room. He was quick to let me know that he shut down the water and saved the other data rooms from being soaked, since they were in line and showed signs of having the same behavior.
That means the investment in the temperature monitoring probes saved them thousands of dollars. If that isn’t the best reason to buy then I don’t know one that is!

Mount Wilson Observatory In Danger From L.A. Fire
I just read this post on Slashdot:
“Mount Wilson is in danger from the Station fire burning near L.A. Their servers have gone offline, but there’s a temporary mirror cam. It doesn’t look good. Picture twenty-four on the L.A. Times photo gallery shows the observatory from the air. If anyone has any inside news on the condition of the facility, I’m sure there are lots of people on Slashdot that would love to hear it.”
It got me wondering about what type of SensorProbes they have. Most companies will never see this size of fire, but even a tiny fire can put a server room out of commission. That is why it is so important to use sensor probe technology to monitor our environment and alert us when something is wrong.
Anyway, I don’t want to use this as a sales pitch. So, let’s use the fire in California to remind us to check our home and office fire detection systems.
My prayers go out to all of the fire fighters, the people who have lost their homes and the people who’s homes are in danger.

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.
