GPFS is a cluster file system that allows multiple nodes to access a single file system or set of file systems simultaneously. The nodes can be SAN-attached, network-attached, a combination of the two, or in a shared-nothing cluster configuration. This enables high-performance access to this common data set, which can support a scale-out answer or…
What exactly is a GPFS cluster? All backed node types, which include Linux, AIX®, and Windows Server, can be used in GPFS clusters. These nodes can all be connected to a single set of SAN storage or via a combination of SAN and network-connected nodes. Nodes can be in a single cluster, or information can…
Components of the GPFS The following components comprise GPFS: A kernel enhancement The GPFS daemon Daemons for RSCT Module for portability GPFS is a kernel module extension (mmfs) The kernel extension interfaces to the simulated file system (VFS) for file system access. Applications make file system calls to the operating system, then route them to…
What exactly is GPFS? IBM Spectrum Scale, formerly known as the General Parallel File System (GPFS), is a high-performance clustered file system software that IBM evolved in 1998. It was initially intended to support high-streaming media as well as entertainment applications. It can be used in shared-disk, shared-nothing, or a correlation between the two distributed…
