OneFS is a fundamental component for Dell PowerScale storage. It is used to power all Dell PowerScale NAS storage solutions and offers the following key advantages:
- Scale-out architecture: OneFS is designed to scale in terms of machine, by adding more PowerScale nodes to a cluster, both performance and capacity is scaled. It enables PowerScale scale to a multi-petabyte large cluster which contains a maximum of 252 nodes.
- Single file system and namespace: Traditional storage model contains file system, volume manager, and data protection. OneFS combines all of them into a single intelligent distributed file system, and provides a single namespace that is accessible through multi-protocol (NFS, SMB, HDFS, S3, HTTP, and FTP) simultaneously.
- Efficiency and ease of management: OneFS provides unique features to improve PowerScale NAS storage system efficiency and ease of management. For example, with OneFS SmartPools, you can tier your cold data to lower-cost PowerScale nodes automatically.
OneFS is not only the operating system but also the underlying file system that drives and stores data in the PowerScale scale-out NAS cluster.
