Abstract
A system in which a file system may operate on a volume in which the logical address extent of the volume is divided into multiple tiers, each tier providing storage having a distinct trait set by mapping the logical addresses of the volume to appropriate underlying storage systems. A volume system exposes the volume to the file system in a manner that the file system itself has awareness of the tiers, and is aware of the trait sets of each tier. The file system may thus store file system namespaces (such as directories and files) into the tiers as appropriate for the file system namespace. A provisioning system may also be provided and be configured to provision the volume to include such tiers, and if desired, to extend the tiers.
