In computing, any case of electric power loss, while computers are working, can cause a data loss.
Data loss might be minimal but all data that is buffered and still not written to the disk, in the moment
of a power loss, could be lost.


Power supply at the storage servers should be provided from the two different sources (dual site
power supply) or at least uninterruptible power supply (UPS) for short term power loss. Dual power
supply units (PSUs) inside the servers should be connected to the power supply at all times.
