摘要
A cluster file system comprises storage server units each configured for communication with a plurality of clients over a network. At least one of the storage server units comprises an object storage server, an object storage target associated with the object storage server, a metadata server, a metadata target associated with the metadata server, and a scale-out network attached storage cluster. The scale-out network attached storage cluster comprises storage directories corresponding to respective ones of the object storage and metadata targets. The object storage server and its associated object storage target may form part of a first storage tier of the storage server unit, and a plurality of nodes of the scale-out network attached storage cluster may form part of a second storage tier of the storage server unit. Parallel log-structured file system (PLFS) middleware may be used to control movement of data between the first and second storage tiers.
