Earthquake-proof storage of seismic data
The seismic data of the Austrian Central Institute for Meteorology and Geodynamics (ZAMG) need to be stored earthquake-proof. A DRBD+ cluster with three-way mirroring was the solution to this challenge. With this solution, data volumes in the range of terabyte are stored in a secure and permanent manner.
The Austrian Central Institute for Meteorology and Geodynamics can thus again observe its duty of providing access any time to seismic data in case of international requests.
Nikolaus Horn is responsible for storing the data and had to face the truly historic challenge of transferring old data that were partly saved on magnetic bands to modern data media. In order to win the race against time, Horn has consulted LINBIT’s open source experts, who managed to solve the issues related to security and data transfer on a lasting basis. The digital data were already transferred to the huge servers with 16 hard disk units each and eight TB storage capacity; the old magnetic bands could thus already be disposed of.
"The main reason to use DRBD has been the fact that we could integrate a technology that is understandable and transparent to me. This guarantees that we are not too dependent on a certain vendor and that we are not helpless if a company loses interest in this kind of product”, Horn explains the decision to use LINBIT’s open source software solution.
