Abstract:
A first physical capacity of a first physical storage device is determined. A second physical capacity of a second physical storage device that has a physical capacity greater than the first physical capacity is determined. A storage space pool comprising at least a first logical drive, a second logical drive, and a third logical drive is created. The first logical drive corresponds to the first storage device and has the same capacity as the first physical capacity. The second logical drive corresponds to a first portion of the second storage device. The third logical drive corresponds to a second portion of the second storage device. The first portion and the second portion having at least the first physical capacity. Thus, two portions having at least the first physical capacity are utilized on the second physical drive instead of just one portion.
