I was reading through the FAQ and followed a lot of links, but I can't find a simple explanation how to add a Cache drive.

Or do I need a different type of drive, if I would like to run VBox, having the OS on a drive not belonging to the Array?

 

I just added a new 500G Drive to the server:

 

1.Stop the array.

2.Power down the server.

3.Install your new hard drive.

4.Power up the unit.

5.Start the array.

 

Now it is clearing the disk, but I dont want this disk to be a part of the array. Could you please give me a hint?

Hint...

Do not add the disk to the array, if you do not want it to be part of the protected array.

 

You can partition it, format it, and use it as you like otherwise.  It will not impact the starting or stopping of the protected array.
