As a VAST Universal Storage system, VAST Cluster stores data neither in a traditional file system nor in an object store, but using an abstraction called the Element Store which serves to present data to traditional file storage protocols (NFS, SMB) as well as presenting data, which can be the same data, to the S3 object storage protocol.
The Element Store is the cluster's namespace for data. It is shared by both file and object storage protocols. The Element Store can simultaneously present data as objects in a flat hierarchy and as files in a hierarchy of directories.
The Element Store can contain a hierarchy of directories, any of which can be exposed to NFS clients as mountable exports, to SMB clients as shares that can be mapped as drives, and to S3 users as buckets for storing objects.
Configuration of NFS exports, SMB shares and S3 buckets is done through the configuration of views. A view creates an Element Store path and exposes it to one or more client protocols.
Permission checking on VAST Cluster is consistent in authorizing permissions to users with multiple sets of user attributes used by different client protocols. Several providers are supported for user authorization.
