Abstract
At least certain embodiments include a method, system and apparatus for relocating data between tiers of storage media in a hybrid storage aggregate encompassing multiple tiers of heterogeneous physical storage media including a file system to automatically relocate the data between tiers. The hybrid storage aggregate includes one or more volumes, each volume including a volume block number space spanning at least a first-tier of storage media and a second tier of storage media of the multiple tiers of heterogeneous physical storage media and the hybrid storage aggregate further includes a control module to cooperatively manage the tiers of the multiple tiers of heterogeneous physical storage media and a file system coupled with the control module, the file system including a policy module configured to make policy decisions based on a set of one or more policies and configured to automatically relocate data between different tiers of the multiple tiers of heterogeneous physical storage media based on the set of policies.
