Abstract
The present disclosure includes apparatus, systems, computer readable storage media and techniques relating to virtualization of data storage space. In one aspect, a system includes: solid-state drive (SSD) devices, wherein each of the SSD devices includes contiguous portions; and a data storage controller configured to assign a priority value to each of available ones of the contiguous portions of the respective SSD devices, based on weighted criteria, and choose a subset of the available ones of the contiguous portions of the respective SSD devices, in accordance with the assigned priority values, to form a logical disk; wherein the logical disk includes at least one available portion from each of two or more of the SSD devices.
