A '''diskless shared-root cluster''' is a way to manage several machines at the same time. Instead of each having its own [[operating system]] (OS) on its local disk, there is only one image of the OS available on a server, and all the nodes use the same image. (SSI cluster = [[single-system image]])

Line 9 ⟶ 10:

The additional abstraction layer between storage system and computing power eases the scale out of the infrastructure. Most notably the storage capacity, the computing power and the network bandwidth can be scaled independent from one another.

A similar technology can be found in [[VMScluster]] ([[OpenVMS]]) and [[TruCluster]] ([[Tru64 UNIX]]-UNIX).

The [[open-source license|open-source]] implementation of a diskless shared-root cluster is known as [[Open-Sharedroot]].
