A movie that makes server switching successful before the server rack dropped from the roof of the building wrecks

A virtual data center is dropped from a high-rise building with each rack, and during that time, a virtual data centerFailoverSymantec releases it as a promotion video. The details of the preparations were introduced in detail, so I decided to check it.

Data Center Down! Behind the Scenes (High Availability & Disaster Recovery) - YouTube


I am trying to drop a server rack from the roof of a building in San Jose, USA.


It will fall at tremendous speed.


Server rack is fine leaf. It falls over and fails over to a virtual data center prepared separately until it breaks.


So, first of all, we will look at how much preparation was done for this experiment. First of all from the first day.


Place where the foundation for dropping the server rack is installed on the roof of the building.


Looking from above it looks like this.


Scenery from the place where server rack is installed. It is understood that it is quite a high place, and if it falls from here, it is convinced that the server rack will also wreck.


I am configuring software to be used for failover.


Using this software, this experiment is to fail over from "DATA CENTER 1" to drop to "DATA CENTER 2" prepared separately.


This time,SolarisupperOracle databaseYaRed Hat Enterprise LinuxIt seems that applications that work on above, presentation layer, etc. were used.


Clustered applicationsVeritas Cluster Serveruse. As data duplication software,Symantec Volume ReplicatorIt is used.


In addition, the set of hardware such as foundation was carefully done.


I was in charge of "32 TEN STUDIOSThe studio called.


In the studio which worked on "Star Wars" "Star Trek" "Die Hard", a full-fledged setting as if to film shooting was done.


I am adjusting the server rack.


The part that operates when dropping the server rack is adjusted to move slowly.


Actually put a server rack, simulation.


The height is 250 feet (about 76 meters)


The speed is 140 fps (about 153 kilometers per hour)


The impact to the falling point is large, so there is a risk of scratching the concrete, so there is only an iron plate.


And the second day.


On this day we actually drop the server rack.


Move to the point of slowly dropping the server rack using the rail.


And at last it is ready for the fall ... ...


It falls in a blink of an eye. The gallery is also "oh" and the expression of surprise.


Parts of the server rack are scattered extensively from the falling point, which indicates that it was a considerable shock.


Looking at slow motion, it sounds like a movie.


It seems that the critical failover was a great success.


Failover seems to have succeeded in a very short time of 5 seconds from the start of the fall. Members exchange high-touch, and we share happiness.


With this, even if the server is destroyed in the event of a disaster, it can fail over to a server located elsewhere in a short period of time before being destroyed.
