OpenSSI allows a cluster of individual computers (nodes) to be treated as one large system. Processes run on any node have full access to the resources of all nodes. Processes can be migrated from node to node automatically to balance system utilization. Inbound network connections can be directed to the least loaded node available.
The compression algorithm and cluster size is specified on a per-file basis. Directories can also be marked for compression, in which case every newly created file in the directory will be automatically compressed with the same cluster size and the same algorithm that was specified for the directory. e2compr is not a new file system.
The most common type of clustered file system, the shared-disk file system – by adding mechanisms for concurrency control – provides a consistent and serializable view of the file system, avoiding corruption and unintended data loss even when multiple clients try to access the same files at the same time.
Linux The Oracle Cluster File System ( OCFS , in its second version OCFS2 ) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License . The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
The Veritas Cluster File System (or VxCFS) is a cache coherent POSIX compliant shared file system built based upon VERITAS File System. It is distributed with a built-in Cluster Volume Manager (VxCVM) and components of other VERITAS Storage Foundation products - particularly VERITAS Cluster Server , VERITAS File System, and VERITAS Volume Manager .
In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories. To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
IBM OS/360 and successors allocate files in multiples of disk tracks or cylinders. Files could originally have up to 16 extents, but this restriction has since been lifted. The initial allocation size, and the size of additional extents to be allocated if required, are specified by the user via Job Control Language. The system attempts to ...
GNOME Disks is a graphical front-end for udisks. [3] It can be used for partition management, S.M.A.R.T. monitoring, benchmarking, and software RAID (until v. 3.12). [4] An introduction is included in the GNOME Documentation Project.
