Title: Distributed metadata servers in a file system with separate metadata servers for file metadata and directory metadata

Abstract

A file system is provided having a plurality of distributed metadata servers with separate metadata servers for file metadata and directory metadata. An exemplary distributed metadata storage system comprises a plurality of compute nodes, wherein at least one compute node comprises a file system client that generates a directory metadata request and/or a file metadata request; a plurality of directory metadata servers to serve directory metadata in response to a given directory metadata request; and a plurality of file metadata servers to serve file metadata in response to a given file metadata request. The plurality of directory metadata servers are distinct from the plurality of file metadata servers. The compute nodes optionally comprise an object client that requests object data from an object store system. The number of directory metadata servers and the number of file metadata servers are optionally determined independently to balance for different workloads, and can be dynamically readjusted for evolving workloads.
