Obviously, the most sophisticated system is pretty useless if it doesn't work. In addition to our regular benchmark suite we simulated a broken hard drive by removing the SATA cable.
This screenshot shows the disk management window after detaching a hard drive and re-plugging the data cable after only some seconds. For safety reasons, Windows does not assimilate the drive into the array automatically. The other array members are indicated as 'failed redundancy'.
Clicking on 'repair volume' will start the rebuilding process.
Of course we need to chose a spare drive before.
