I just checked all my fire alarm batteries for the winter period, we do a lot of wood fires so i always make sure there safe before going to bed.

Well written post. It should be noted that the Exinda x60 next generation WAN Optimization appliances do allow for export of URL information within our Netflow v9 flow export records and we can define dynamic control policies to limit access to certain domains if desired.

It's amazing how much power just a few servers can consume. Waste not, want not. Great post!

While tech companies are trying to outdo each other in data center design and energy efficiency, small businesses still can find choosing a data center a tough proposition.

Great idea. I'm currently also freezing in my cubicle. At my old place of work, people used to have space heaters under their desks - talk about a double waste of energy.

Amazing! Such a wonderful post. I never knew that. I believe that I'll be waiting for your next posts.

To avoid destroying your smoke detector and not waste your batteries, turn it off and check if all its parts are
functional.

There are those who hire a professional installer while there are those who attempt to do it themselves to be more independent or to save money. Either way, the important thing is that you are showing how much you value your family and home's safety by adding a protective measure against potential danger.

Re: Help desk: How sensitive is your motion detector sensor?

OLIVER HOWARD — Fri, 10 Dec 2010 13:36:40 -0000

I have an older model motion detector that was installed before I came to work in this office building. It is a ceiling mount that is square with one light sensor, how can I find the model and manufacturer.
Thanks.

Re: Five major data center outages reported last week

anevermind - You are correct, more then likely these larger centers had other signs of an issue. My point was that other small to medium size networks who are connected or related to the larger scale providers could be alerted in a shorter period of time.

Thank you for sharing in detail about Ravica smoke detector.Smoke detectors is must to secure us during hazardous situation.Providing emergency call is an added advantage of it.Motion detectors can also be used to secure our home.

That's cute and all, but detecting an outage is not the problem; i suspect very strongly that folks knew about the failures. Sometimes major power infrastructure fails, and cheap monitoring is not going to stop that..

Mike,

Just wanted to let you know that our site has been updated. You can find information on our SNMP solutions here:

Chipkin is actually one of our partners.

Let's see if S4 and Ravica can find some synergies!

Re: Should we Recycle Server Room Heat?

David O'Coimin — Wed, 14 Apr 2010 09:10:52 -0000

Hey Jimmy. You guys should consider putting your gear into a Kell PSE (Portable Server Environment). We're working hard to get the world to understand that you don't need to build Server Rooms anymore. The heat from the equipment can be used in winter to reduce your heating bill (on top of having already removed the cost to cool your server room). Makes too much sense to ignore, right?

Re: Data center power outage alerting

Mike Hamershock — Mon, 01 Jun 2009 13:46:00 -0000

Thanks. I'm not too concerned about my servers - all our gear is dual-sourced for power, and each cord is off of a different UPS feed. Going on UPS or even loosing an entire UPS feed "should" have little to no impact due to our design, and so far in practice this has proven true.

My concern is that I have experienced (more than once) a complete loss of UPS feed when a UPS goes to bypass due to an internal fault and the STS does not fall over to the reserve (secondary) UPS. This is mostly an issue at colos since I don't control the design - some don't use an STS and rely on gens for feed when a UPS goes to bypass. When this occurs and the BitSight is powered by that string, I will lose all data from the sensors on that Bitsight. We used to have this issue with Cyclades remote console systems - they've addressed the problem by having dual power inputs on their gear now. If I am to rely on Ravica units as a part of my enterprise monitoring system, and if they are to be considered critical systems, they need similar redundancy. I'm just sayin..... ;)

Re: Data center power outage alerting

Jon Mills — Sat, 30 May 2009 10:29:44 -0000

Hi Mike,

Really, you can have the BitSight getting power from anywhere you want. It can be the same UPS the sensors are monitoring or a different one all together. If there is an emergency life line string then throw it on that. The point of having a BitSight in place to monitor your UPS is more to know when you are using battery backup vs. line voltage, not when your UPS is failing. Ideally the Ravica systems in place have already notified you that you are running on limited battery life well before the UPS is drained.

The fact of the matter is, if your BitSight is on an emergency life line string and the UPS supplying its power goes down, then any systems that it would use to alert you (e.g. web servers, mail servers, VoIP servers, etc.) are going to be without power as well. Which would make keeping the BitSight online a moot point.

But like I said, the real idea here is to be proactive and get the alerts well in advance that say, "Hey, your power went out and you are on battery backup. Time to shut non essential systems down and keep business critical apps running for as long as possible."

Hope that offers some additional insight.

Re: Data center power outage alerting

Mike Hamershock — Fri, 29 May 2009 16:29:59 -0000

Since the Ravica BitSight units are single corded for power, what do I plug it into? The same UPS string as the sensors are on? A different UPS string? What happens when the UPS powering the BitSight drops? Then I lose all visability to the sensors. The Bitsight heads really need to have dual corded design so that they can stand on 2 separate UPS strings.
