Abstract
A cluster file system comprises a burst buffer appliance coupled to a plurality of object storage servers via a network. The burst buffer appliance comprises a controller configured to implement storage tiering control functionality for at least first and second storage tiers comprising respective disjoint subsets of the plurality of object storage servers. The burst buffer appliance is thereby configured to control movement of data between the first and second storage tiers. The object storage servers in the first storage tier may be configured to interface with object storage targets of a first type and the object storage servers in the second storage tier may be configured to interface with object storage targets of a second type different than the first type. For example, the object storage targets of the first type may comprise non-volatile electronic storage devices such as flash storage devices, and the object storage targets of the second type may comprise disk storage devices.
