1. A multi-tier storage system, comprising:

  • at least first and second storage tiers comprising respective disjoint subsets of storage for storing data from at least one compute cluster comprised of a plurality of compute nodes, wherein said first storage tier comprises at least one burst buffer appliance, wherein said at least one burst buffer appliance comprises a memory for storing data and at least one processing device to transform at least a portion of said data for storage on said second storage tier based on a mapping of a plurality of said burst buffer appliances to at least one corresponding stripe on said second storage tier, wherein the transformation of the data by the at least one processing device of the at least one burst buffer reorganizes an input-output workload into a network stream having an improved alignment, relative to an alignment prior to said transformation, for transferring said data in parallel from said first storage tier to corresponding objects in said second storage tier.
