Using Samba with a Commercial Clustered File System: Using Samba with a Commercial Clustered File System


Agenda: Agenda Isilon Clustered Storage Overview Developing OneFS Samba and OneFS Clustering Samba Future Requirements


Isilon OneFS Cluster: 3 Isilon OneFS Cluster Vertical-Specific Imagery for this sequence Work Vert-Specific Single file system (1.6 PB) Fully symmetric peers 3 to 96+ nodes Fast intra-cluster network InfiniBand Multi-protocol access CIFS NFS FTP HTTP/WebDAV Local userspace


What Makes Isilon OneFS Special?: 4 What Makes Isilon OneFS Special? Single pool of storage Granular data protection Down to the file level 8x mirroring or +4 recovery Easy to manage and grow Add additional nodes in 60 seconds Automated data balancing Extreme performance for concurrent access POSIX and Windows semantics supported

CTDB on Clustered File Systems: 16 CTDB on Clustered File Systems Leverage Existing Technology CTDB is a promising solution for POSIX clustered file systems Some file systems extend capabilities Native distributed locking mechanism Native cluster membership tracking Native ACLs and other feature obviate need for specific TDBs Native solutions benefit from Performance tuning Build on existing testing and deployment Samba should benefit from these capabilities when available


Samba 3 Wish List: 17 Samba 3 Wish List Abstract interface for TDB based solutions Kernel based solutions and CTDB coexisting Existing examples iNotify for Linux NTFS VFS layer in Samba 4 Beneficial to other vendors Moving forward…


Samba 3 Wish List: 18 Samba 3 Wish List Increase communication Share our features and bug fixes Minimize parallel development Vendor specific branches? Ease merge burden Moving forward…
