SELECTING DATA NODES FOR WAN CACHING IN A HYBRID CLOUD ENVIRONMENT

Abstract:

A computer-implemented method for storing blocks of a file in a heterogeneous environment. The method may comprise receiving a command header for an operation associated with a file from a first data node, matching the enhanced metadata with capabilities of a second data node, and generating a block layout map for the file based at least in part on the enhanced metadata and the capabilities of the second data node. The command header may include enhanced metadata associated with a file, and the enhanced metadata may comprise a type of workload that generated the file and a data access pattern.
