Because the node-based architecture of OneFS allows near-instantaneous, downtime-free file system expansion, Helix depots that are stored on a PowerScale OneFS system can take advantage of the OneFS architecture and increase the capacity of all depots stored on them without system outage or downtime.
The OneFS operating system provides the intelligence behind PowerScale scale-out storage systems. It combines the three layers of traditional storage architectures—file system, volume manager, and data protection—into one unified software layer, creating an intelligent file system that spans every node within a cluster. OneFS is a single-file-system, single-namespace architecture, which makes it easy to manage at any scale. The storage systems powered by OneFS are simple to install, manage, and scale.
Adding capacity and performance capabilities to a cluster is significantly easier than with other storage systems—requiring only three simple steps for the storage administrator:
The new node provides additional capacity and performance because it includes CPU, memory, and network. The OneFS AutoBalance feature automatically moves data across the back-end network in a coherent manner, so that existing data residing on the cluster moves onto the new storage node.
