Abstract
A volume system that presents a volume having an extent of logical addresses to a file system. A volume exposure system exposes the volume to the file system in a manner that the volume has multiple tiers, each offering storage of different traits. This is performed using multiple heterogenic underlying storage systems, each having different storage system-specific traits. Each underlying storage system may be hardware, software, or a combination thereof that permits each storage system to expose storage having the particular storage system-specific traits to the file system. The volume system supports each tier by mapping logical addresses of the tier to portions of underling storage systems that are consistent with the tier traits.
