Abstract
A method implements a hierarchical cache system with a parallel Network File System (pNFS) configuration for a storage system. Upon receiving a request by the hierarchical cache system to access data stored in the storage system, the method divides the data into a plurality of data segments and distributes the plurality of data segments to a plurality of cache servers of the cache system. The method responds to the request a metadata layout for the plurality of data segments distributed among the plurality of cache servers. Based on the metadata layout, the plurality of data segments can be concurrently retrieved from the plurality of cache servers.
