Abstract
A processing device identifies a file (or data block) and selects a storage location for the file based on a plurality of data distribution policies. To select the storage location, the processing device applies, at a top distribution layer, a first data distribution policy to select a first storage pool from a plurality of storage pools based on a first storage criterion. The processing device then applies, at a bottom distribution layer, a second data distribution policy associated with the first storage pool to select a first storage node from a plurality of storage nodes in the first storage pool based on a second storage criterion. The processing device stores at least a portion of the file in the first storage node of the first storage pool.
