DO Block Storage



As my database space runs low, I’m thinking about to attach some block storage on Digital Ocean. As I’ve read in the block storage announcement this should be possible:

“Once Block Storage has been attached, all the application web files and databases will be stored on the Block Storage.”

Is it possible to extend database space afterwards a second and third time by attaching even more block storage? Or is this just possible once?

What about CPU. Is it possible to increase CPU regardless of the attached block storage as often as needed?
