Abstract: The present technology provides a two step process for providing a linearized dynamic storage pool. First, physical storage devices are abstracted. The physical storage devices used for the pool are divided into extents, grouped by storage class, and stripes are created from data chunks of similar classified devices. A virtual volume is then provisioned from and the virtual volume is divided into virtual stripes. A volume map is created to map the virtual stripes with data to the physical stripes, linearly mapping the virtual layout to the physical capacity to maintain optimal performance.
