Abstract

Space allocation for non-volatile memory is shown. A controller establish a first namespace set by allocating the non-volatile memory in units of a first storage unit, and establishes a second namespace set by allocating the non-volatile memory in units of a second storage unit. The first storage unit is bigger than or equal to the second storage unit, and the first storage unit has better input and output isolation than the second storage unit. The first namespace set and the second namespace set are in the different tiers in a hierarchical storage architecture.
