Cluster Shared Volumes (CSV) is a feature of Failover Clustering first introduced in Windows Server 2008 R2 for use with the Hyper-V role. A Cluster Shared Volume is a shared disk containing an NTFS or ReFS (ReFS: Windows Server 2012 R2 or newer) volume that is made accessible for read and write operations by all nodes within a Windows Server Failover Cluster.
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
Category for shared disk file systems. Shared disk file systems (also cluster file systems or SAN file systems) are file systems that can concurrently share access to a single block device from multiple computers.
A shared-disk file system uses a storage area network (SAN) to allow multiple computers to gain direct disk access at the block level. Access control and translation from file-level operations that applications use to block-level operations used by the SAN must take place on the client node.
Like typical cluster filesystems, GPFS provides concurrent high-speed file access to applications executing on multiple nodes of clusters. It can be used with AIX clusters, Linux clusters, [6] on Microsoft Windows Server, or a heterogeneous cluster of AIX, Linux and Windows nodes running on x86, Power or IBM Z processor architectures.
The server component of Distributed File System was first introduced as an add-on to Windows NT 4.0 Server, called "DFS 4.1", [5] and was later included as a standard component of all editions of Windows 2000 Server. Client-side support is included in Windows NT 4.0 and later versions of Windows.
Note that in addition to the below table, block capabilities can be implemented below the file system layer in Linux (LVM, integritysetup, cryptsetup) or Windows (Volume Shadow Copy Service, SECURITY), etc.
The collection of computer hosts that comprise a OneFS System is referred to as a "cluster". A computer host that is a member of a OneFS cluster is referred to as a "node" (plural "nodes"). The nodes that comprise a OneFS System must be connected by a high performance, low-latency back-end network for optimal performance.
