Line 1: A '''Diskless Shared-root Cluster''' is a platform for [[High Availability]] Infrastructures. A Linux cluster filesystem, e.g. [[Global File System\|GFS]] or [[OCFS2]], is the basis to form a [[single-system image]] (SSI) on filesystem level with any attached [[Storage Area Network]] (SAN). But also a NFS server on the network may be configurated to host the generic boot image for the SSI cluster nodes. Although such NFS based Diskless Shared-root Cluster are not recommended for productive environments, NFS still could be used to build cheap cluster infrastructures for less important tasks. The architecture of a [[diskless]] [[computer cluster]] makes it possible to separate servers and storage array. The operating system as well as the actual reference data (userfiles, databases or websites) are stored competitively on the attached storage system in a centralized manner. Any server that acts as a cluster node can be easily exchanged by demand.
