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

Security monitoring – camera applications
Our customers that are looking to take environmental monitoring to another level often ask about our camera monitoring support. I thought a short article on the applications would be useful to some of our regular readers.
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!

Securing your data center with Ravica equipment
Filed under: Data Center, Intelligent Sensors, Security Monitoring, SensorProbes
I started working with an interesting client today.
The company is a small hosting service provider with approximately 100 clients. What made this company different was that their clients would come on site quite often. Each client would has a key card; this identifies who is coming in and out of the server room. The problem is that the cards were being handed off to other employees. Since the company promised the utmost in security, this started to become a concern.
The goal of my client was to provide a video record of each entry. To accomplish this, I suggested that we add security sensors to each door. This would tell us when each and every person went through the door. Next, we added multiple security cameras, to record who was in the server room. The dry contact sensors would also give us a good idea of when the person left. The next hurdle was the lights, since they are off most of the time.
We used the Sensor Controlled Relay to turn the lights on and off in the room. This gave the security cameras more then enough light for recording. This was implemented via the alert from the trigger of the security sensor.
The Sensor Controlled Relay is easily controlled by any of Ravica’s extensive selection of sensors. The relay can provide automatic responses to sensor alerts. This made it easy to configure a scenario where the security sensor on the door was tripped and the lights were turned on.
In the end, the process worked perfectly. When a customer entered the server room, not only was their entry logged via the keypad, but they were also getting video record of that visit. We are currently working on providing a common interface between all of the data sources.

Five major data center outages reported last week
Filed under: Data Center, SensorProbes, power monitoring, smoke detector
The website Data Center Knowledge recently published an alarming report about five major data center outages that occurred in the past week. Here is a brief breakdown from the article.
- “On Monday June 29, Rackspace Hosting (RAX) experienced a power outage at its Dallas data center that left several areas of the facility without power for about 45 minutes, knocking many popular customer web sites offline.
- “Early Thursday Equinix Inc. (EQIX) data centers in Sydney, Australia and Paris each experienced power failures. While the power outages were brief – Equinix said the Sydney event lasted 12 minutes while power was restored in Paris in just one minute – many key customer sites took considerably longer to recover their systems. The Sydney event led to disruptions for VoIP service in parts of Australia, while the Paris outage caused downtime for the popular video site DailyMotion and the French portal for hosting firm ClaraNet.
- “Google App Engine, the company’s cloud computing platform, had lengthy performance problems on Thursday, experiencing high latency and data loss.
- “A fire at Fisher Plaza in Seattle late Thursday night left many of the building’s data centers without power. The fire in an basement-level electrical room triggered sprinklers and caused extensive damage to generators and electrical equipment. The damage left tenants with backup plans offline for hours, and those without backup sites down until temporary generators restored power early Saturday morning. The biggest impact was at payment gateway Authorize.net, which was offline for more than 12 hours, leaving its merchant customers unable to process credit card sales. Other sites experiencing lengthy downtime included AdHost, GeoCaching and Microsoft’s Bing Travel.
- “Early Sunday, July 5, a fire at 151 Front Street, the major carrier hotel in Toronto, knocked out power on several floors of the facility used by Peer 1 networks. Power was restored in about 3 hours, after a damaged UPS unit was bypassed.”
The author, Rich Miller then goes on to point out some tough questions and the lessons learned from these outages.
Although it is surprising that data centers of this size can experience an outage like this, what is even more surprising is that it all happened in a week’s span. I wonder, is the National Security Agency going to look into this?
The equipment used to monitor this size data center is monumental, but even the smallest IT department can obtain economically priced sensor equipment, like the Bitsight8, combined with Intelligent Sensors, like the AC Voltage Detector and the Digital Voltometer.
The future of data center design
Filed under: Data Center, environmental monitoring, humidity monitoring, temperature monitoring, water leak monitoring
I just read that the NSA is going to build a 20 acre data center in Utah. This one million square foot center will allow the NSA to decentralize its efforts and provide better security. Just imagine the amount of power it will take to operate a data center of this size? This Slashdot article points out that one of the biggest reasons why the 
government is building this compound is due to its power consumption and the current location’s inability to provide the needed electricity. The government estimates that it will use at least 65 megawatts of power or about the same amount that Salt Lake City consumes.
“The agency got a taste of the potential for trouble January 24, 2000, when an information overload, rather than a power shortage, caused the NSA‘s first-ever network crash, taking the agency 3 1/2 days to resume operations. The new data center in Utah will require at least 65 megawatts of power” - Salt Lake Tribune
Another cool data center design is the one that Google is planning to build. The entire center will be built on a floating barge, and will use the waves of the ocean to help power the facility. It will also use ocean water to cool the equipment.
Last, but not least, is the underground data center in Sweden. This has to be the coolest data center ever! It is located underground, can withstand a hydrogen attack, has a waterfall and a greenhouse. It can generate its own power, and is equipped with triple redundancy Internet backbone access.
I wonder, what type of environmental monitoring sensors do they have? What type of redundancy and fail-safes? Designing a data center like these is a monumental task. I can’t wait to see what the future holds for Data Center Design.

Make environmental alarming more obvious
Filed under: Data Center, Intelligent Sensors, SensorProbes, environmental monitoring
Many times we see the monitoring equipment placed into a data center, where it does its job and becomes lost in the sea of electronic gear. It sends out alerts for temperature, humidity, smoke, gas, water etc., via email or syslogs and that is fine and good.
I have a suggestion. For $125.00 we can add a strobe light and audible alarm device to your BitSight or SecurityProbe.
If you leave it in the data room, no one will see or possible hear it. If you put it in the hallway like we did, it will catch everyone’s attention when something goes on.
If something goes wrong in our data room. Everyone will know!

3 Tips for Data Center Security
We put a high focus on protecting the data center from environmental disasters, like extreme temperature and humidity, as well as water leaks and poor air circulation. However, there are other considerations to be made in keeping the data center safe, like physical security conditions. Is all of the sensitive equipment being protected from unauthorized personnel?
Of course the first order of business is to set standards and procedures that make those in charge of data center security aware of exactly what is acceptable clearance and what is not. However, as is true for almost any kind gateway, mote, or minefield, people will find their way around. So there must be systems in place that keep us alerted to situations that are potentially hazardous.
The Ravica SecurityProbe can increase the level of data center security by providing insight in the following three areas.
Keep an eye on your data center
As the saying goes, “Seeing is believing.” We need to be able to see with our own eyes that everything is truly alright before we can really breath easy. Nothing beats being there, but if you can’t be there, then a video camera presence is the next best thing. With the pan-tilt dome camera, your SecurityProbe can watch up to four separate locations. It can even be programmed to move to a specific location when an event is triggered from any type of sensor. It will also take a series of snapshots and include them with email alerts when triggered by any sensor.
Batten down the hatches
It seems obvious, but the most important places to monitor in secure areas is the entrances and exits. That means, tighten up the doors and windows. Ravica security sensors are contact sensors that are perfect for letting you know when a door or window has been opened. The idea is relatively simple. There are two contact plates. When they are separated, like when the door edge moves away from the frame as it is opened, the sensor switches to an alarm status.
What’s in motion?
A great fail safe, in addition to watching the doors and windows with sensors and cameras, is monitoring for motion. Motion sensors can also sense for unauthorized access, or can simply be the trigger for telling a camera to pay attention to a certain zone. Make sure that the right amount of movement sets off the sensor in a sensitive area and it can mean the difference between knowing during or after a security breach has occurred.
Whether you are guarding Fort Knox or your small corporate data center, putting a SecurityProbe and the appropriate sensors in place can go a long way towards keeping unauthorized personnel away from your sensitive equipment and information.
