Open-Sharedroot
Encyclopedia
Open-Sharedroot is a single-system image
clustering solution for Linux
.
The Open-Sharedroot Project is based on a clustered filesystem like the Red Hat Global File System
(GFS) or Oracle Cluster Filesystem 2 (OCFS2) to build a Shared Root Cluster.
All nodes possess concurrent read/write access to the root filesystem.
Based upon this technology it is possible to boot a cluster directly out of a SAN
. This Shared Root variant is known as Diskless Shared Root Cluster
.
Single-system image
In distributed computing, a single system image cluster is a cluster of machines that appears to be one single system. The concept is often considered synonymous with that of a distributed operating system, but a single image may be presented for more limited purposes, just job scheduling for...
clustering solution for Linux
Linux
Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The defining component of any Linux system is the Linux kernel, an operating system kernel first released October 5, 1991 by Linus Torvalds...

Global File System
In computing, the Global File System is a shared disk file system for Linux computer clusters. This is not to be confused with the Google File System, a proprietary distributed filesystem developed by Google....

Storage area network
A storage area network is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to make storage devices, such as disk arrays, tape libraries, and optical jukeboxes, accessible to servers so that the devices appear like locally attached devices...

Diskless Shared Root Cluster
A diskless shared-root cluster is a way to manage several machines at the same time. Instead of each having its own operating system on its local disk, there is only one image of the OS available on a server, and all the nodes use the same image...
