GlusterFS GlusterFS is a free software clustered file system capable - PowerPoint PPT Presentation

GlusterFS ➔ GlusterFS is a free software clustered file system capable of scaling to several petabytes. ➔ GlusterFS aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. ➔ Storage servers (bricks) can be made of any commodity hardware. ➔ Theoretical peak performance is the aggregated performance of all the units. ➔ Advantage – easy to deploy and maintain ➔ GlusterFS is implemented as a FUSE file system for GNU/Linux, and relies on the underlying file systems that already have received a lot of attention to detail. ➔ GlusterFS stores files and folders as it is on the back-end disk (like NFS). Even striped or mirrored files will look like regular files on disk. User can recover the files and folders even without GlusterFS ➔ GlusterFS is fully POSIX compliant
