Are your server racks prepared for aftershocks?
Numerous aftershocks occur after a major earthquake. With Yacmo's “Server Utena”, an automatic homing function protects your valuable servers even after a large aftershock.
issue
Aftershocks are a common occurrence after major earthquakes, and in many cases, the seismic isolation equipment that withstood the first earthquake has shifted from its home position (original stage position). If left in place, the motion range of the seismic isolation stage cannot be maintained, and several aftershocks can cause a server rack weighing over 1 ton to tip over. If aftershocks occur when workers are on their way to the site to restore the origin, the safety of workers, which is the most important aspect of earthquake countermeasures, is threatened. On the other hand, if the server rack is equipped with a mechanism that automatically returns to the origin position under its own weight when the shaking subsides, the server can continue to operate without human intervention, thereby reducing the risk of aftershocks.
counter-measure
Yacmo's seismic isolator “Server Utena” uses circular arc rails, which automatically return to the original position when the earthquake shaking subsides (automatic origin return function). After an earthquake, there is no need to return to the origin, and the server rack is always in its full operating range of seismic isolation performance, so it continues to protect the server rack from earthquake shaking regardless of whether it is a main or aftershock.
result
In the Kumamoto earthquake that occurred on April 14, 2016, there were several large aftershocks after the main quake, but the servers of our customers with our seismic isolation system “Server Utena” were able to continue to operate without collapsing under such circumstances.
