ABSTRACT:
Provided are techniques for processing read and write request operations. Regions of a first storage device and a second storage device are designated as primary regions and secondary regions for read request operations and write request operations falling within the regions. At least one write request operation is processed. Upon determining that a write threshold has been reached, the designations of regions of the first storage device and the second storage device are switched.
